Great video! I did use a product that contained sodium percarbonate. I did dampen the deck prior to application. I used a stiff brush to apply and agitate. I then let it sit. Directions said to let it sit, but it was drying out. I don’t have a power washer, so I defaulted to a hose. I should have said at the beginning, this was a new cedar deck from September 2023. Our carpenter said to seal it in the spring since he felt it needed to dry. After winter it needed a good cleaning. We’ve had nothing but rain and tornados since spring. The hose just didn’t seem to remove the product it looked like a gel or slim residue was left. I tried rescrubbing and hosing it off, a squeegee, nothing seemed to work. This morning it looks blotchy, I’m really at a loss. I may have to contact a pro locally at this point. I can send you a picture if you like. I’m really at a loss. Thank you for this video & your time. 😊

You think I can come work with you to educate myself?

What would you recommend for a New Hampshire (non-coastal) house with western red cedar shingles? They are about three years old, untreated, and starting to grey and blacken variably around the house. I would like them to age naturally - but I don't think it will age uniformly (a little difference is fine). Should I simply have them cleaned every few years? Solid stain? I like your channel and would love any advice you have.

Is there a recommended treatment for new red cedar siding? We live in Syracuse NY, and love cedar sided houses. Should we leave the shingles bare and natural or as far as products what would you recommend- I.E. CedarShield / or a transparent / hydrophobic / mildew-cide? I’m interested in preserving the natural look of the shingles, and have decided to not stain or paint. There’s a lot of techniques / products - however, I know houses in Cape Cod are the benchmark that stand the test of time.

I heard people using diluted bleach for a brightener. Can you tell us why to avoid it, even when on a budget? Thanks.

Thanks!

Wow, incredible! I used your method on my redwood deck. The oxalic acid applied while still wet works wonders. Now, do I leave it or stain it? I would love to leave it and observe deck life without stain . However, it has been stained twice before and so, I will probably do that again. I am using a new stain called Penofin; it contains a mildewcide. We'll see what results I get. Live and learn, it's a glorious thing,

Didn't explain enough. Like what chemicals are used to remove a problem like algae.

Thank you!

What method do you apply the oxalic acid with? Good video.

Great advice and great Channel thank yOu

This is a really great video! Thank you so much! I know for sure we need a professional now lol

I've got a job on a cedar sided house where the home owner wants only the lower half of the house to be restained. The upper portion of the house actually seems to be in good shape but the lower is peeling. Last stained 15 years ago with Sikkens. I'm hesitant to only do the lower half and spoke with them about the large possibility that the color would not come out the same. Is it even possible for me to treat with sodium percarb on the lower half, power wash, and then restain the lower portion? Would I need oxalic in this case if I were going right to stain? Seems like a bad idea to me and will be really inconsistent.

Beautiful!

I have used a power washer (DIY Clueless) on my brick patio that is soft set ( sand inbetween each brick). What a mess that was. Sand all over me, all over the house. It took forever to follow the outline of each brick. It looked great when I was done but the time it took was too much. I just purchased a Briggs and Stratton surface cleaner and so much cleaner and faster. Thanks to you Nate, I will be applying some sort of detergent from now on. I am looking forward to the results. Thanks!!!

Hi, what chemicals did you use for cleaning and how did you apply them?

The insurance companies read out of a book. They have no common sense. They don’t care whether you chemically treat it or use a turbo nozzle. This is very unfortunate.

What do you use to bring out the dark wood tenons before the Oxalic acid?

Insurance is about taking money, not giving money. I have business Insurance, vehicle insurance, home insurance and many more for the last 25 years and not ones have I claimed, but the price still surge.

Hello from the seacoast of Maine 😊

Hey Nate, awesome video. I had a customer get a letter saying they needed to have their shed roof cleaned! They were going to cancel their policy if they didn’t get their shed roof cleaned? Like maybe just not cover the contents of the shed if there’s a leak. They’re outrageous.

Powerwashing an area rug that I hung up under my deck. I didn't take the time to secure all four corners and used my hand instead. Pulled trigger, wand jumps, deep slice above my left thumb. Good news, it was a clean cut and made life a little easier for the doctor to sew it closed. Oh yea, no nerves were hit...Luckeeee. Love yourself enough to slow down and enjoy the process. PS Poison oak and ivy is an oil. If you use a wash cloth and Lava soap it will strip the Urushiol oil from your skin. kzfaq.info/get/bejne/atWpoqeDrda1e2Q.html

Hi Nate! I bought a bunch of white cedar shingles that have been sitting outside over a year under shades not covered.. I want to clean them before installing as siding. What would you recommend for cleaning? I dont think there were any big chunky moss but gray here and there.

this doesnt work on pressure treated

What do you use to spray the mixture?

This is how 99.99% of shingles on Cape are installed and have been for hundreds of years. They shrink just like the ones you showed had shrunk after being installed tight. The cupping and bowing is usually on south facing walls where shingles have been cooked by the sun for years. Just like you are likely to see moss or mildew on the north facing wall. Go back to that house in a few years and show the same wall, shingles will be gapped.

Hey Nate, quick question. Are you batch mixing your precarb the morning of or the night before?

How much pressure (psi) is safe for cedar? Great work btw cheers

As someone who's never used a power washer. I'd be worried about messing up the stones with the power washer.

If only these exterior cleaning contractors existed in Baltimore city. The neighborhood Facebook pages are flooded with recommendations but then you talked to the guys and they are doing exactly what you say… no insurance or wrong insurance, power washing rather than soft washing, sending crew out that aren’t experienced. Sigh… so here I am doing it myself, when I really wish I could bring someone in to do it for me. It’s not even about the cost, I just want it done right! Thanks for all your advice.

Any advice on how to get the black spots and streaks in the wood (pressure treated pine - Baltimore MD) to cleanup? I’ve tried treating and scrubbing and 40 degree pressure washing without any luck.

Thank you so much for the video! Very helpful indeed 🙂. I have a ramp as well that's needing attention.

@Outside Cleaners - great tip as always Nate. Thank You.

A lot of nouns flying around but no verbs talking place. 🤔

Great video. Thanks for the info. I’ve been sponging or setting up a sprinkler on them them since day one.

Thank you so much for sharing your expertise! Just wondering, would you do anything differently (or additionally) for prep if there is old stain already on the siding and I want to restain. I am not sure what was on there before so I will test a few different samples after cleaning but probably go with something darker and semi-transparent or solid. I know that you aren't a painter but perhaps you have done prep for a paint crew or homeowner that intended on staining?

Wow

Hi man! I appreciate your videos, helped me a lot. I was about to change from SH to oxygen bleach. And i just tried normal laundry detergent. It’s said it contains sodium percarbonate. So i used 12 gallon of water and 3,5 pounds of the laundry detergent (it was a small roof). And i don’t think it worked so well. My question is how strong (%) hydrogen peroxide do we use on a roof, how strong needs the mixture to be to clean the roof well. Thank you for everything 👏

question: is the sodium percarbonate downstream injected after mixed or is the the mix being applied?

So did you use chems or just wet and then brushed and then pressure ???? Thank you ....

whoah you destroyed the roof with your chemical braaa!

Nate get a gutter cleaner tool there 25 bucks I got mine on a telescopic pole Makes for 2 ladder placements. Reach out to 10-15 feet From the left and right.

I try to always leave a window opening

Ive always used sh to wash a roof then I encountered a house that was stained and had to use percarbonate. I’m thankful for your videos!

Do you recommend sealing the wood after this clean? Or just leaving it? I'm also in the northeast with a 1980s built cedar clap board and losing my mind about it 😂

Very wise!

@Outside Cleaners- Nate, truer words were never spoken.

So in your opinion whats the best way to move forward, a chemical strip with hydroxide?

how long do let the chemicals sit on the deck before rinsing off??
