Thank you. Appreciate that.

@@SamkoWorkShop I tried it on my deck this afternoon but it did not work. I used Clorox which has 8.3% Sodium hypochlorite without diluting it and the green and black algae were exactly the same after 2 hours. What I'm I doing wrong? Please help.

[@SamkoWorkShop]

@FT-ql7lc I can't believe that is possible. 10 minutes and it should of ate most of it up. Not sure what's going on. Unless the clorox was so old it lost it's power. Bleach is only good for about 3 months and then looses potency

Excellent video explanation of mixing and percentage of SH

[@SamkoWorkShop]

Thanks glad you enjoyed it

[@makycaris4672]

Lot of these people talk 3% -6% etc for example a six percent gallon of bleach in a 2 gallon sprayer u put 1 gal bleach one gallon water that makes it 3% or 12% gallon of bleach to sprayers 50/50 mix makes it 6% ? If makes sense

[@SamkoWorkShop]

@makycaris4672 that is correct. However my experience from 4 years of washing houses professionally is that for vinyl siding 1-2% is all that's needed. On wood that's not super dirty 1-2% works great and on not very dirty concrete 2% works good. You can up the percentage as needed. But when you get above 2% you start risking burning up grass, flower, plants, etc and have to pay much more attention to your rinsing before and after. As a professional we hit stuff with hotter mixes to get it done quick and right the first time but we also know what we are doing and what it takes to protect the surrounding landscape. But for a home owner the best advise I have is use the lowest ratio you can that does the job and keep everything saturated wet that you don't want bleach on.

[@ItchyKneeSon]

A chemist friend of mine who spent 5 years (successfully) leading a team to developing a biocidal house paint (which the company hid/buried) said that you don't want to go over a certain percentage of bleach in the mixture because the natural defense mechanisms of algae and/or mold will trigger, preserving itself. I don't want to quote the number because I don't actually remember. lol 4% was definitely safe, though.

Fantastic information thank you. Can I use this for white plastic fences around the house and or the shingle on the house or gutters etc?

[@SamkoWorkShop]

Yes. But for the fencing and gutters you only need about a 1 to 1.5 percent bleach mix. For the roof shingles you need about 4%. And again, water all vegetation really well that's around it.

[@NickAngus]

@@SamkoWorkShop Thank you

[@stma111]

absolutely awesome video ! Question about concrete: The foundation of my home has developed a "reddish" stain on it. I'm assuming its a "leeching" of my heavy clay soil here in Pennsylvania. Would your bleach mix take care of removing these stains?? If so, what ratio/percentage would you recommend.....Thanks much, Steve

[@SamkoWorkShop]

I would try the beach first as it will kill all the organic staining. I would do a 3% ratio If there is grass and vegetation around it and still water the grass and vegetation through the process. If not worried about greenery that go 5%. Then for the red stains I'd use oxcilac acid or mutaritc acid in a pump up sprayer. Spray on and then if needed agitate with a brush or broom. Remeber to wear gloves and a mask and eye protection with the acid. That's what we use as pros to remove iorn and rust stains.

[@makycaris4672]

I’m hustling this industry is high in demand if u know what ur doing

Thank you for the video. Will this work on a stained deck with a clear topcoat without stripping the topcoat and stain?

[@SamkoWorkShop]

Not sure. I would do a test spot some where not seen to test it and see.

[@TheAliSareini]

My apartment deck looks terrible like this but I don’t have access to a hose. Do you think a handheld sprayer like that would be enough to wash away the bleach (2%) after application?

[@SamkoWorkShop]

I would rinse it with 5 gallon buckets of water poured on the deck. you want to rinse it good to stop the bleaching process.

[@laurencunningham143]

Wonderful video! As a furniture restorer, would this work on old moldy wood furniture as well? I have read that bleach works best on non porous surfaces like tile, so I’ve been using borax to kill the mold in my antique wood furniture.

[@spawky3158]

@@SamkoWorkShop Great, appreciate the quick reply!

[@daleschimpf]

I see other videos saying to add some dish soap as well. Wondering what your thoughts are on that? Great video. Thanks for doing it.

[@SamkoWorkShop]

You can. But dish soap on wood does nothing. That works for vinyl siding and windows. Pointless on wood. The reason they use it on vinyl is its non porous and the soap acts as a surfactant to hold the bleach on the slick surface. Wood is porous and will absorb it just fine.

[@daleschimpf]

@@SamkoWorkShop thx for the reply. Makes sense. So perhaps using soap could be applicable on a non-horizontal surface such as painted wood/vinyl siding (as you mentioned ) or cleaning algae off asphalt shingles.

[@SamkoWorkShop]

@daleschimpf on the wood fence might help a bit. On shingles everything need to change. On shingles you want to run about 4 or 5% bleach mix. And you want to use persil laundry detergent instead of dawn. And you want about 1 ounce of persil per gallon. Persil is the best surfactant to hold the bleach on shingles. You also need to heavily water everything below the roof the whole time as it takes a hot mix of 4-5% to work on a roof and that mix will kill plants grass etc. Also wear a respirator mask. When sodium hypochlorite hits a hot roof it turns into a gas and is not good for you to be breathing.

[@daleschimpf]

@@SamkoWorkShop while I need to wash decks, walls, AND kill algae on roof shingles, the first issue I feel I need to address is the roof algae so this is great information, and the reason I was asking about using soap. It is often hard to glean exact details from other “roof washing” videos I’ve watched which usually just say “use bleach” and “add some soap”. Finally thanks for the heads up re wearing a respirator.

[@SamkoWorkShop]

@daleschimpf happy I could help. Remeber soak all vegetation below the roof line drip edge really really well. The solution to pollution is dilution! That's the rule of sodium hypochlorite

[@bensmitten2702]

how would you rinse a t&g ceiling?

[@SamkoWorkShop]

with water on a an angle and quickly as possible with a fan tip so you dont over saturate it.

[@rickeykeeton4770]

How do you keep a deck dry enough to let the bleach do it’s job? NW Alabama here. The bleach drys out really quick in direct sun. I tried a little detergent but not sure how much it helped since it too would need a fine spray with water every few minutes it seemed. That being said, I think I am going to have go with a stronger blend like maybe full strength especially on the uprights in the fence part.

I have some old weathered stockade fence around the property and just want to kill the green algae then stain it with used motor oil and Diesel but don't have access to any outdoor water,, what happens if I don't rinse off the bleach? just let it dry and then stain it ?? Thx

[@SamkoWorkShop]

You will want to rinse the bleach off the wood, or it will just keep eating and turn it bright white. I have never let bleach dry on wood to see it personally, but that what I hear.

[@Elkmonger]

It seems like my white vinyl fence went years without needing to be cleaned then it got some algae on it and I pressure washed it and holy cow now it comes back each year with a vengeance. Is it possible the pressure washer roughed up the vinyl and now gives the algae a better environment to start? Is there a product I could spray on and leave on that would hold off the algae growth to where I can maybe only "need" to clean the fence every couple years and I can spend more time shooting my longbow?

[@SamkoWorkShop]

The pressure washer just knocks off the surface alge and doesn't kill it at the spor level. Spores hide in the microscopic lines of the vinyl. Use the same set up I describe in the video but take the raptor down to 1.5-2% mix. Spray it on the fence and then rinse 5 mins later with a hose. It will be spotless clean and all organics killed at the spore level for a fresh factory new fence.

[@giantslayer473]

I have a job cleaning a trex deck next Saturday! Im still not sure what I should use to clean it with. What mixture? Can I use some sort of mix of bleach and water and soap? Thank you in advance! I was going to use like a 1 - 2% bleach and water mix, with some soap, low pressure (below 3,100 psi), and probably a bristled brush with long handle.

[@SamkoWorkShop]

You are spot on. But probably won't need the brush. I'd so a 2% mix, no soap and let it sit for 5 mins then pressure wash. So small sections with the bleach so it doesn't dry on you. Like 10x10 area then wash.

[@SamkoWorkShop]

When he pressure washed it he feathered the surface. Never use a pressure washer on wood unless it's light pressure to rinse. He should of soft washed it like I show here and let the chemicals do the work. Otherwise the feathering will hold dirt, moisture, mold etc and go back to black quickly. Best thing to do now is sand it. Then stain or seal it or paint it. The sanding will remove all the feathering.

[@terryschrock9866]

[@SamkoWorkShop]

All beach is sodium hypochlorite. So all the same. Difference is the percentage of sodium hypochlorite in it. That percentage is what you need to water down to get the 2-2.5%. Pool sticks is a better value as a gallon of pool shock is 10 or 12% and cost 5 bucks. A gallon of bleach is half that percentage yet cost the same. So pool shock is twice the value.

@SamkoWorkShop Hi Sam, Great video! After cleaning a deck with a bleach solution do you feel it is necessary to neutralize the deck before restaining it? I have some areas with mold and mildew and some areas where the stain has worn away to the bare wood. Some bleach based deck cleaning solutions indicate it should be followed by a wood brightener product because bleach based cleaners can increase the pH levels in your wood, causing it to darken. A brightener is suppose to lower the pH level to restore the wood to its natural color and help open the wood’s pores so that the surface is more receptive to stain. Your thoughts? And might you have a DIY wood brightener recipe? Thanks!

[@SamkoWorkShop]

Honestly don't know. Stained decks are very tricky. That's why I did not do them. Some stains will be OK with bleach so will not. And even the pressure washer can destroy the stain if not used right. Best way might be a mild soap and a brush

@@SamkoWorkShop Thank you for your reply! Do we purchase household bleach or sodium hypochlorite from a chemical company? It’s all very new to me

[@SamkoWorkShop]

@Letters1to7 chlorox and most bleach is 5 or 6% and pool shock is 10 or 12%. Both are the same thing just different potency. The key is to get the mix down to 2-3% sodium hypochlorite by adding water. As a professional pressure washer I only buy 12% pool shock as it goes much further for me money wise. At lowes etc a gallon of bleach is 5 or 6 bucks and a gallon of pool shock is 8 or 9 but twice the potency. Either way water it down so the sh ratio is about 2-3% for wood. And make sure you soak all vegetation down real well like I show in the video.

Is chlorine or bleach better

[@SamkoWorkShop]

Same thing. Just water it down to a 2% mix

@@SamkoWorkShop I haven't bought anything yet. So whatever is better. I have a large deck that was stained about 2 years ago when it was new. It has black mold looking stuff on it. What one would be best and would rinse off best? Without leaving white residue. Thank you for you fast response and help. I really appreciate it

@jaytab3686 buy 10% pool shock liquid from lowes or home depot or a pool store. Mix 1 gallon pool shock to 5 gallons water. Do a test spot somewhere unseen as many stains will get eaten by bleach. If thr test spot works good then you know the stain will hold up to the bleach. Stained wood is always a tricky one because the bleach and stain don't always work good together.

For you maybe. But for many the ratios and warnings are important

[@knottyboy6086]

Uh that is a 50 percent mix. You math is WAY off. That is bad dude.

[@SamkoWorkShop]

My math is spot on. The mix ratio is for the amount of sodium hypochlorite, not the amount of fluid in a bleach bottle

That shed looks terrible I understand if we were still leaving in the woods to look like that but y’all colonized us 😂 go to Home Depot

It's a rental house. Not mine

Boring. Don’t give up the day job.
