HOW TO: Clean Underside of a Deck

[@fullmylegroundsllcmyles970]

Great information 👍

[@OutsideCleaners]

Glad you liked it

[@jamelgrooms1849]

Can I use a normal pump sprayer for the hydrogen peroxide? Followed by a low pressure wash?

[@OutsideCleaners]

Yes 👍🏼

[@thefabulousfox2287]

Thank you so much for taking the time to make these videos! Each summer, my husband and I stare at the underside of our deck in dread and promise ourselves "next year," and now it's time to pay the piper. What is the hydrogen peroxide to water ratio?

[@OutsideCleaners]

3% hydrogen peroxide as applied

[@steveabsalonson931]

So are you using only a straight 3% hydrogen peroxide solution with no water; or are you mixing 3% hydrogen peroxide with water at what ratio per gallon? Have you used other alternatives like Vineger w/ water or Borax w/ water. If so, why do you think Hydrogen Peroxide is more effective ​@OutsideCleaners

[@OutsideCleaners]

@@steveabsalonson931 again, it’s 3% hydrogen peroxide as applied. I use this for this application because it’s easy and it doesn’t bother my skin or nose and people are happy with the results. I have never met any homeowner who is happy with their home smelling like vinegar, and I’ve never met any proponent of vinegar gets the results I get with hydrogen peroxide.

[@steveabsalonson931]

Nathan​@@OutsideCleaners. I like your informative and honest approach in you videos. Thanks for your quick reply to my question. I have a 12 yr old cedar deck w/ some significant black mold growth on most of the underside of the boards. So a bit distressed in how I'm going to address the problem.....when I thought I was ready to stain after cleaning the topside. Whatever method I use, need to limit overspray on an already cleaned/sanded topside. Seattle/PNW is terrible climate that facilitates mold, mildew issues. Thanks and I do appreciate your helpful video.

So what should an owner do with that wood? Can it be covered or sealed in some way to prevent this in future?

[@OutsideCleaners]

I'm not a fan or advocate of trying to "seal" wood especially in this upward-facing situation. If somebody wanted to do something to help keep this clean, I'd recommend a spray application of something like Zep "Clear Shell" Mold and Mildew Inhibitor. It's non-toxic and made of chitosan... basically derived from the shells of crustaceans such as shrimp, crabs, and lobsters. Follow the directions, it'll make a profound difference in keeping this mold and algae from returning.

[@GooogleGoglee]

@@OutsideCleaners interesting thank you. Mostly I was curious because to me it looks like that wood will get old and break apart without proper sealing. But it is just me thinking and wondering. I know nothing about that's why I was asking. Thank you in advance ☺️

[@charliefoxtrot7219]

Hello, I'm in Seattle so we may have some similar wet weather to your location. My mother - in -law, 83 yrs old, has a deck in a deck similar build and condition to the one in your video. But the decking is a Trex type material. Would you still use only Hydrogen Per Oxide or a combo of Per Oxide and Bleach? I've heard to use Bleach mix on Trex type materials. The concrete pavers below the deck are covered in Moss. I'm thinking the Moss will need to be scrapped off. I have a Stihl RB 600 3 gal. per min at max 3000psi. Thank you,

[@Rick-qq3vi]

What is the mixture? How much peroxide to every gallon of water? Just curious how long did it take for the deck in the video! Thanks

[@josieandy5874]

Great info man! I have my first ever underside of a deck coming up next month, and I didn't want to use Sodium Hydroxide or Sodium Metasilicate for the same reasons of getting it one me. Glad I watched with video, it makes a lot of sense!

[@OutsideCleaners]

Thanks for watching. Please subscribe and tell your industry associates; I’m really trying to do right with this channel.

[@josieandy5874]

Hey man, just did that deck job today and it went very well! I got soaked in the process. I didn't want to purchase all the necessary hydrogen peroxide, so I opted to use sodium percarbonate, since I already had it, and it worked very well. In your experience, do sodium percarbonate and hydrogen peroxide perform about the same when it comes to cleaning wood like this, or is one better than the other? Thanks!

[@OutsideCleaners]

@@josieandy5874 glad it went well! When it comes to cleaning wood like this, I think sodium percarbonate solution does better than diluted hydrogen peroxide. But when I’m taking a shower in it, I prefer the diluted hydrogen peroxide for reasons I mentioned..

[@josieandy5874]

Gotcha, appreciate the info man!

[@scottpratson7766]

@@OutsideCleaners can you use it on a stained oil stained deck?????

[@hillshepardson9537]

Nate is that sodium percarbonate?..Thanks for

[@splanzza]

Did you listen at all what he was saying! 🫵

[@OutsideCleaners]

Hey Hill, this was actually 3% hydrogen peroxide, not from sodium per-carbonate powder. When it’s gonna rain down on me, I prefer just hydrogen peroxide versus the sodium per carbonate mix..

[@zakfisher4271]

Will peroxide take organics off vinyl?

[@OutsideCleaners]

Hydrogen peroxide is a biocide and so Yes, it will help remove organics from vinyl. However, it will need more forceful rinsing than a stronger chemical, and more rinsing will tend to shove water up the weep holes, leading to dirty weep hole drizzle (lol ugh). For that reason, to clean vinyl siding I prefer using a detergent-heavy solution with a small percentage of sodium hypo (like, 0.5%).

Great video. How long does the hydrogen peroxide need to sit before you rinse it?

[@OutsideCleaners]

Just a few minutes is fine

What kind of saftey glasses you wear? The longer i do this the more and more i care about ppe. Started wearing gloves 2 years ago and so pissed i went so long without them.

What did you quote this? Trying to learn about cleaning wood and that to charge

[@OutsideCleaners]

The question of "how much" has come up many times lately and deserves its own video. Please stay tuned.

[@anneszy]

what percentage of 3% did you use? did you use it full strength or did you dilute it?

[@OutsideCleaners]

3% peroxide Undiluted 100% of 3%

[@ohiodeerhunting2552]

Is hydrogen peroxide safe to use on areas where SH is not safe to use?

[@OutsideCleaners]

Not totally sure what you mean by areas that sodium hypo not safe to use. Hydrogen peroxide won’t leave bright chemical stains on bare wood like sodium hypochlorite (bleach) will. But, both will smoke most flowers in bloom unless precautions are taken.

[@ohiodeerhunting2552]

By safe I was thinking of chemical stains. I would like to get into more exterior cleaning but am a little leery about damaging or staining areas if using the wrong cleaning chemical or solution. I'm just trying to sort out what is safe to use on different surfaces - stained wood, unfinished wood, painted wood, limestone, metal etc.

How do u clean the ground under deck that u can't walk under.

@@dellajones806 I don’t!

[@ashleysilva7414]

When using 35%, one must be very careful and when diluting with water it will generate heat. Be careful.

Where do you buy bulk hydrogen peroxide?

[@tonybersano2428]

Why not just use sodium percarbonate, it's alot cheaper

[@OutsideCleaners]

@@tonybersano2428 Thanks for your question and thanks for watching. Agreed that sodium percarbonate is cheaper. I illustrated this job with hydrogen peroxide for 2 main reasons: 1) Many viewers are homeowners who only have a pump sprayer for application, and therefore have a difficult time applying sodium percarbonate solution because it often doesn't entirely dissolve, clogs up the pump sprayer nozzle, etc. Hydrogen peroxide doesn't have that trouble with a pump sprayer. 2) The exterior cleaners who watch this channel are mostly set up with a typical downstream injectors for sodium hypo application. Sodium percarbonate solution can't be effectively downstreamed... but hydrogen peroxide can. Lastly, as I mentioned somewhere, sodium percarbonate *seems* to dry out my skin a lot more than hydrogen peroxide does. When I'm going to be "bathing in it" as in this overhead job, and the quantity of either is small, I prefer hydrogen peroxide.

[@darkhorse6770]

So basically, "Sodium percarbonate" dissolved in warm water will do the trick 😊

[@OutsideCleaners]

That will work fine or even better, but for this I used and prefer straight 3% hydrogen peroxide. As some viewers always point out, sodium percarbonate mixed with water makes hydrogen peroxide (H2O2) and sodium carbonate (Na2CO3). Sodium carbonate is caustic and while that probably makes for a better cleaning solution, on jobs like this where the cleaning solution is basically going to be raining down on me, I prefer to use just hydrogen peroxide. After doing this of years I've found my skin is getting a little sensitive to caustic ingredients and gets itchy after exposure. When I use JUST hydrogen peroxide, I don't experience that issue.

[@darkhorse6770]

@@OutsideCleaners where do you buy a giant container full of hydrogen peroxide?

[@OutsideCleaners]

@@darkhorse6770 I buy in various bulk sizes and concentrations from regional chemical distributors. Homeowners can buy gallons of 3% online or gallons of much stronger to dilute down to 3%. I had put some Amazon links in the video description.
