Pressure Washing Concrete Driveways

How to pressure wash concrete driveways. MORE INFO → www.howtowithd...
The girls drop by and help Doc pressure wash his concrete driveway using two pressure washers and various surface cleaners. Concrete driveways are easy to clean as long as you have the right equipment and that equipment is properly matched.
When you clean your concrete driveway the use of chemicals is not needed. Just the power of water via these powerwashers is really all you need. The surface cleaners reduce labor time by up to 50% and reduce over-spray.

I'm not going to lie, your grass is in amazingly good shape! I've never seen something so green!

[@keyeskennard]

To fix the K.A.RCHER Head, run a 1” sheetrock screw through the plastic nut all the way through the other side. It will not come loose after that. Hands down the best surface cleaner! Purchased last year with pressure washer upon your recommendation. Amazing!

[@russb5234]

As a pressure cleaning contractor I just want to point out that when you do a very inconsistent job with a surface cleaner and you overlap a lot on one area of concrete and don’t overlap the same amount on the entire driveway you will get a very streaky and patchy driveway in a couple of months maybe less. Some overlap is necessary on every job and you will get some striping no matter what but keeping it to a minimum and doing the same amount of passes on all the concrete will minimize the striping.

[@davidragusa2200]

After watching this video, I took Doc's advice and bought a surface cleaner, and the Simpson machine. Everything works great. Thank you for the informative video and the solid advice.

[@diamond6256]

DUDE You got some really pretty helpers. I am also a woman (65) and doing mine this next week. I have already done my back patio and sidewalk area. I do have red spots on my patio and will try the 30 second cleaner. THANKS.

[@rudolphgutierrez5323]

Thanks Doc! I just purchased the Simpson 4200 , paired with the Ridged 18” surface cleaner, can’t wait to fire it up!

[@jonifejes6815]

Great Doc....found these videos for Father’s Day 2022

[@Irwhodunit]

Thanks for the tip on the pump saver. I've got a can but didn't know when to use it. Can I find the hose extension at Home Depot or Lowe's?

[@j.a.r.family2576]

I really appreciate your opinion. And the fact that you love your yard and still walk on it and use it. Also. Props to the ladies for being such great helpers.

[@Hugo_Furst]

Thank you.. I have the Karcher 15" too. Excellent performer. I'm glad you mentioned the center item comes loose and can be re-tightened because that just happened to my cleaner.

[@musicfan6575]

Karcher Surface Cleaners are Great!! I use the same one you showed along with a Excell 3100 psi and it has made me a few bucks for a side Gig. Thanks for the Awesome review!!

[@johnbustos3033]

Recommendation on removing mold from concrete; additional pressure or cleaning solultion? What type of concrete sealer do you recommend? Would like to see your fence project once completed. Thanks

[@bodocki1155]

Glad I stumbled across your site. Quick question on the karcher surface cleaner.. I have the Simpson 3300 PSI/2.4gph with a Honda motor.. You said you had a 3300 also. Do you use the Karcher on that also even though it's rated for 3200 psi?

[@robertscarpetti4656]

Dear Doc; Many thanks for your wisdom and valuable insights and knowledge. I am very very grateful to you and your efforts!!! Do you have any recommendation for the power washers gun's hose, the one I use is very difficult to use and is very rigid? Also, any recommendations for quick connects for the hoses? Many thanks again, you are a great man!

[@needinfo2614]

I purchased(online)the Simpson 3125 MegaShot, extended 31" wand and the Karcher surface cleaner and received them from Home Depot 4/21/21, used them on 4/22/21 for several hours and returned the Karcher to HD 4/23/21. The unit basically became unusable due to the 2 large plastic nuts on each side of the unit. They constantly came loose resulting in a useless vibrating disk unpleasant to use, finally the nuts could not be tightened any further and the spinning of the unit rendered it as useless and annoying. Bad experience, will research other surface cleaners for possible purchase. Very disappointed with Karcher but like the Simpson 3125.

[@patrickcarver3607]

Thank you! I have been researching surface cleaners for a few days now and I have the same PSI and GPM pump that you have in the video.

[@enriquepazwebdevelopment]

Just started my pressure washer adventure and want to add comments about chemicals. I had a driveway that was sitting under a large tree had lots of deep mold and algae and I had very good results using vinegar and lemon juice as the agents instead of man made chemicals, works like a charm try it first before buying. Also dawn dish soap and borax made in to a paste is very effective for oil stain removal. Great channel hope to see more. Any experience with pohl brand pressure washers or accessories? I have their surface cleaner and it seems very durable caneceith extension etc.

[@moahs5682]

Yet another great and informative one, Doc! Lots of well thought out info to put in the mental vault and then pull out as needed. Joe S

[@user-jx9qo9lf3t]

If you can't find those short hose connectors I use copper quick-connects. The male on both hoses and on my pressure washer and all of my sprayers and nozzles I have a female. So easy cause you are right about hot exhaust.

[@simaovissi8085]

Hello Doc. Do I need to seal my driveway after pressure washing?

[@slimdawgwoof]

How nice that your children help you! Can you do a video on how you accomplished that? Mine seems to flee if I ask them to please hand me the hose. :)

[@nahnisjourney1406]

Do you recommend a pump saver in the Greenworks 2000 PSI electric power washer?

[@littlefinkle7757]

Got a Stihl surface cleaner. Using a Simpson 4000PSI washer. If you dont really hold on, or adjust the pressure down, the surface cleaner will get air born!

[@frankiii5823]

I pressed the like button just off the intro before I even got to the content. nicely done!

[@alvekovius361]

Doc, thanks for the advice. Where, exactly, is the list of recommended equipment? All I see are viewer comments...

[@jenwilliams2714]

Super great videos! :) I just purchased a Simpson PS-3228-S. I unpacked it, set it up and started washing my backyard. Question: The Simpson PS-3228-S as you know has an adjustable throttle. When I push it to full the engine starts to pulsate, speeds up and bogs down over and over very fast, and the unit starts to bounce and thinks about walking. If I ease off the throttle by 20% it smooths out. I allow it to warm up at a lower RPM, then speed it up to start power washing. What do you think is causing this and how can I fix it so I can run the PS-3228-S at full throttle? I'm using Shell unleaded 91 Octane, and Sta-Bil 360 fuel stabilizer. Thank you! :)

[@wklemp57]

Had the same problem as you had with the KARCHER cleaner, as far as nut coming loose. Simple solution loosen nut add a drop or two of permatex ( I used red) loctite, re-tighten, problem solved.

[@ac7384]

Can you use the pressure washer with the surface cleaner to wash wood deck. If so wbat psi ?

[@haroldlawson3567]

Ehhh… what’s up doc??? (In my Bugs Bunny voice) I just wanted to say thanks for the time and effort you put into your content for us. I came to learn about cleaning driveways and I also learned about algae and mold which brought me to leaving this comment. Thanks for that. I wasn’t expecting it. So again. Thank you and a big 👍🏾 for the girls. They’ve earned it.

[@curtislewis5437]

Very informative, Thanks from Mississippi.

[@DiggingRob]

Just bought a surface cleaner for my power washer.......I recently purchased a (clog hog) jet drain for my power washer...... totally cleans all my slow drains in my house

[@lisaboyd2773]

Love the girl's !!!! Thank you so much for the video. Alpharetta, Georgia.

[@luvinmysailor]

Hey neighborhood!! Gwinnett county here😍

[@CJ-Rexng]

Will the “Karcher” surface cleaner attachment work with the larger 3300 Pressure washer ?

[@b.b.5048]

So, basically what I'm taking away from this is the biggest advantage to surface cleaner is I can make my kids do it. SOLD.

[@eveoliver6846]

Thanks Doc! Great literature. I am working my lawn also.

[@rejeanpaquet4375]

Thanks for sharing your expertise. Kudos to the girls, good job 👍like the drone shot.

[@dirkayala5812]

Glad I just stumbled onto this vid, My new Washer just delivered last weekend and so far just put it together, been on the fence about which surface cleaner to buy so IO have held off last 2-weeks, did however order up a cheap extension to try out off Amazon though. Looking forward to this now!:)...

[@Thewaldo12345]

So still doing the curb sump pump or no? Still the only person I’ve ever seen do this.

[@AerialLensVideo]

FANTASTIC and so very helpful - Thanks!

[@purplefreaks74]

Doc, can you make a video on pressure washing your car and brick patio? Thanks. Love your videos!

[@sebastianshaw5534]

I'm willing to bet the people in your neighborhood feel some type of way... because your driveway and yard is always looking great. It forces everybody to keep up.

[@gabbyleiba3866]

Sebastian Shaw nah he look like he lives in HOA Neighborhood

[@marmstrong2981]

You can also try the Ryobi Water broom which do a very good job.

[@jack765ful]

I noticed they're washing right over the expansion joints. Would this damage the existing caulking in the joint?

[@keitha.9788]

Your recommended "beefier" pressure washer is nearly identical to my DeWalt pressure washer (same Honda engine, slightly different AAA pump). On your Simpson surface washer, it can be disassembled and a steel or brass flat washer added to make it rotate smoother. Good Review. Thanks.....

[@carlhall2563]

Did I miss where you talked about which pressure washer to get?

[@gmo709]

Cool. I just bought a Karcher power washer. Didnt get the disk/hovercraft thing yet. Lotta,birds there. Peaceful.

[@aa0517748]

Sweet clean team.

[@c.n.h4841]

Thank you for the time and doing this video to help ppl

[@definitelyduse]

Lol that intro definitely earned u a subscriber 💪🏾👌🏾👌🏾👌🏾

[@beretiatabenteti28]

Are those surface cleaners fit in any pressure washers regardless of brand? I have a homelite 2700 psi.

[@CheranePefley]

Great demonstration. "thank you LADIES"

[@michaelmijatovich8983]

Ok my question is there are so many surface cleaners out there but how do you decide on one. My pressure washer is old but wasnt used much and I fried the pump awhile back and getting a new pump until I get my dream machine it's a troy bilt 5 hp not tons of pressure. So what surface washer is good with out costing me alot

[@jaredreyes2811]

Hey Doc, quick question. What do you recommend to remove rust stains on driveways?

[@gingerwood1969]

Jared Reyes I’m not the “Doc”.....but the best product to remove rust stains from almost anything is “GOOF OFF RustAid outdoor Rust Stain Remover”. It will impress you! One gallon costs about $9 from Menards or Lowe’s. Or just buy online.

[@guttercleaning2115]

I have a Greenworks 2300 PSI electric pressure washer. It works well. Should use pressure washer saver in it?

[@JoeJoe-wp1vv]

Smashing Pumpkins fan in da house, lol. Good Vid. Thanks for the tips, I'll definitely check out the link.

[@Chefvatche]

Do you have any tips and tricks to clean pavers that are sealed. I am OK if the sealant comes Off because the contractor did not do it right it’s all milky

[@weldchip]

i have the Karcher, little tip on the nuts, dump a bunch of loctite/thread locker on the threads and do it up, let it dry for a day or two and it wont work loose anymore.

[@fitzfitz2801]

i have several power washers im getting older and like the electric ones better i recently bought a 3800 psi electric and now want a different surface cleaner but im finding all the high pressure rated ones are saying gas powered only ??? whats the difference ?

[@pmr413]

Thanks for the video and all of the tips. I just ordered the items you have linked on your website. Thanks again!!! ~Pat

[@chuckadeuce1]

Great vid doc! What kind of fence are you putting up? Does the lattice count against 6ft code? Sorry looking forward to ur status update.

[@brianelsner4175]

So it was going to be a side-by-side comparison but after the first shot they both had the same unit?!🤷‍♂️ Did the all black one suck that much that it was swapped out after 6ft?

[@user-qs8lv7wp2c]

I bought a 2700 pressure washer with the attachment you recommended for concrete. My question is I have fertilizer rust throughout the whole slab. it was there when we bought the house. However even after pressure washing it the walkway which is about 14 feet by 4 is still Orange could this be that that's just the color of the concrete they used for the walkway I can't get it to turn white at all, only gets little better, Even though you said not to use any type of chemicals I've tried pool chlorine, Ox White, even muriatic acid and still it's orange any help would be great

[@michaelwilliams2954]

Hey Doc. I cleaned my job driveway with a BE warlaway 20 inch surface cleaner with bleach and a little dish detergent and the water ran onto the New asphalt they just got done. How do i get the stains off the asphalt

[@davidjanzen8519]

Hey Doc. I'm interested in getting a GC190. Love the videos. I have an older honda pressure washer that has had some neglect. When you start it it moves arround on the concrete. And leaves marks from the rubber o n the unit.? Is it ready for sick bay? It's about 10 years old. Thanks

[@MrDBonilla062]

Thumbs up to the girls. Great job. I just a pressure washer and I had to buy the surface cleaner after I saw your video lol!! Just bought that today and about to clean my backyard the ground. Thanks for your tips. Very helpful

Hi, i am in 61 now and was thinking about maybe starting a little pressure washing business... i don't need to make a ton just a couple of hundred per week...do you have videos on this topic?... i would like to do mostly pool decks and driveways... can i get by with out bringing my own water tank??? thanks for all your help.

[@daveborchard2019]

Do you have a video about power washing paver driveways? I've searched for a video by you about power washing paver driveways, and haven't found it. Thanks for your recommended power washer and accessories to buy. I'm going to order them soon, so I can clean my paver driveway, before the HOA sends me a notice that I have to power wash my driveway.

[@johntamulonis4626]

Great stuff, I have a question about how long I can pause my pressure washer, I have a brand new Generac 3200 PSI and it works great. My question is when I am working along and I need to pause and I release the trigger to say move something my engine starts to struggle so I immediately squeeze the trigger and do my chore with the triggered squeezed worrying about the engine. I have great pressure but when that trigger is not squeezed it runs rough. How long can I not be pulling the trigger and what the engine is doing when water is on at the faucet but not coming out of the wand. Thanks.

[@HowTowithDoc]

While they have a temp relief valve... any pause longer than say... 30 seconds should be a shut down. Moving the unit is fine..changing tips is fine... but don't let it sit and run for extended periods.

[@johntamulonis4626]

How To with Doc thank you for the wick response

[@thomassylvestro9041]

I have a Simpson PW 3000 PSI and 2.4GPM the unit comes with a morflex 1/4 x 25. I want a 50" hose morflex has a 5/15 x 50 option. Are there any issues with the larger diameter hose or should I stay with a 1/4" diameter hose?

[@amywjn]

Thanks for the good info. That was one loud bird, thought it may attack.🤣

[@dmd.damien]

Hello! I was wondering about the SIMPSON MegaShot 3000 PSI at 2.4 GPM HONDA GCV160 . Is that a good power washer to start a small business? Where I live I will be doing small bits of area not really full drive ways but it may come to that eventually.

[@godblessthelessfortunate3175]

Hmmm. The first surface cleaner you discussed in the video, a no name brand, which you didn't like looks identical to your favorite, the KARCHER. Why don't you show both side by side and compare the differences?

[@michaelsera746]

Wish you did a review as well on SurfaceMaxx Pro 4500-PSI Rotating Surface Cleaner purchases in lowes. All metal, wheels and ball bearing rotating wand. My experience with 2550 psi washer is average and needed to use turbo nozel on a few spots. Is the product fancier than it looks or is my PW just to weak? Thx

[@bsce100]

So what chemical should I pre-treat my driveway with? I don't understand. How about post treatment?

[@kapilkirpekar3433]

Hey doc, will the pressure washer cleaners like zepp or bleach or “30second” cleaner harm the grass if the water runs off into the grass ? Also the soaps used to clean cars I. The driveway. Will that soap runoff harm the grass ? Thanks

God bless, Barb!

[@damianyoung2751]

Love the video doc very helpful info 2 questions 1. what camera are you using to shoot the footage facing the girls pressure washing the driveway and 2. When you take the Ariel shot what camera are you to get that full view . Thanks

[@sumitgoswami3626]

Did really great job girls. 👍😎

[@spear-it]

Great video! I use a Dwalt 4000PSI on my channel

[@Igor-q3f]

How do you apply the 30 seconds cleaner? The instructions says 1:1 ratio, then you need a pump sprayer going on the ladder. If you use the soap Injection hose on power washer, that’s about 10:1 and it’s too weak.

[@JR007x]

great vid, thank you! i always appreciate the links as well. regards to the last step with the spray cleaner, it wasn't in any of your links. can you share?

[@mrtonestar1]

Hello Doc love the video awesome very intuitive, Sorry slightly off-topic what camera did you use for this video?

[@juansebastianlopez8828]

Hey Doc quick question, my pressure washer is 3600 PSI, came with a 1/4 in × 25 ft pressure hose, can I use a 5/16 in × 40 ft 3700 PSI hose with it? Also, can those 2 be connected to work together? Obviously with the right quick connect adaptor.

[@210psychoholik]

3200 psi surface cleaner ,Can these be compatible with a 2300 psi pressure washer!?

[@mobetterg]

Hello from 🇺🇸Harrisburg Pennsylvania 🇺🇸 Thanks for providing us DIY PEOPLE these kinds of videos 😎 They are Very useful, My Question to you is there a alternative pressure washer hose that you recommend ? Cause the SIMPSON MorFlex that comes with this Pressure Washer is very hard to work with 😟. Also what is the largest pressure hose can you use with this machine 50 feet ? 100 feet ? 200 feet ? ? ? ? 🥳 Thanks So much for your help 🥳 Enjoy your weekend 😷🦠😷

[@williamcroom4482]

I have a Homelite 2800/2.5 system with a 15 inch Karcher surface washer. I just finished a tennis court and driveway. I can see patterns where the washer traveled after the surface is rinsed and dried. How can I avoid this? Should I repeat the wash at 90 degrees? Thanks.

[@jonathana7019]

Post treat the surfaces with SH. The streaks will be gone.

[@Habitarse]

I saw your video about protecting the water system, when cleaning driveways and paths when water plus chemicals would get in the drainage system. In continental Europe we have a strict law, about the materials of your driveway. It must let water get through to the ground to avoid erosion and floods. As well we cannot use detergents or chemical of any kind to clean it, just water, cold or hot. I know that in the US build concrete driveways are cheap but it comes to a huge costs for nature. The new laws here have change the tax system, because too many people would almost close the entire garten with concrete or asphalt. Now you pay more taxes on your property if you don’t use materials, that allows water to get through. It means that you have to use permeable materials or leave large cracks between tiles.

[@williamwoodham687]

Awesome video Doc. Question? Have you ever tried the tennis ball gimmick in the handle at start up and shut down just to keep the water running through and avoiding back pressure build? This is also very important when using diesel fired heaters on big time pressure washers. When I do stadiums I also use the tennis ball when in constant use as in many hours . This helps with muscle ache from constant squeezing. Just my dime Doc. You taught your girls well. Have you ever also wanted to show the wrong way in regards to injury management. Twisting back muscles and the such. Thanks Boss man.

[@JJYSGYAJY]

Tennis ball method? I am guessing placing a tennis ball between trigger and trigger guard during start to relieve back pressure. Correct? Good idea!
