I’m guessing that it’s cedar from the searches that I’ve done. If so I’ve read that cedar is one of the softer woods. I’m thinking 3% Sh with minimal elemonator followed by a good rinse and then oxilac. Should hydroxide be used in this case?
Haven’t done a ton of these, but the number one thing I would urge you to do is wash from the bottom up. In my experience you’ll leave streaks in the shake siding if you wash from the top down. We use a standard house wash mix, maybe a little hot if needed, and wash/rinse like normal expect bottom up.

Start off with no more than about 1.5% That should be plenty. Strong hw mix may get it but may have to go up to 2%. Don’t need hydroxide.

Will it need to get close up attention like a deck? I’ve always done decks & fences with sodium perc or house wash mix and I would need to go over every inch of it with a 4011, 12, 13, or 15 tip. I’ve been seeing people suggest hotter mixes and/or hydroxide and a literal rinse. I’m going likely pass on this one if there’s not an easier solution then tedious wand work. I’ll probably pass on it anyway but I’m still curious as to the proper/best method here.
Hand split red western cedar shakes. ( Not really sure, but i believe its cedar)

You should do it. No different than a shake roof except easier because they’re just cedar shingles. It’ll be absolutely beautiful when done. You’ll need to experiment with it to dial in mix. Don’t have to use high pressure. Can do the rinsing with your m5ds. What are they planning to do with it? Do they just want cleaned or are they going to restain? Find that out first. Guarantee some of our New England or Michigan guys have done cedar shingled homes before. @Patriotspwashing , @Infinity

I don’t touch the stuff. There’s a company near me who I refer all the tricky stuff to: roofs, cedar, decks, etc.
If it’s not vinyl, aluminum, composite, or painted/solid stained wood, I don’t wash it.
Sorry I can’t be more helpful on the topic

Same here I don’t touch it either too much easy money on vinyl
Man, I wish there was more vinyl here. Most siding here is hardiboard. At least the LP composite stuff is 99% gone.

Cleaned only. As long as it won’t require pressure I’m game. I’ll do some more reading
I’m having a hard time finding information on it. I’ll try out the fb groups.
Thanks. Have you used this product?
No, but its next on my list. Lots of cedar shakes in older communities nearby, so gonna give it whirl.
I had to find something jist in case I get that odd customer who wants safe organic type cleaners, this should shut them up. I dont mind tho.

Basically sodium percarb. There’s a guy on YouTube that uses all of their products and does a lot of cedar shake on Cape Cod.

That’s the second thought that I had but every time I’ve used sodium per carbonate I’ve ended up having to use some pressure over each board. Maybe cedar is different or my mix wasn’t strong enough. I have over a thousand feet of fence that needs to be cleaned out back. Although it’s not cedar I think it’s time to try some strange stuff and put my mad science hat on.

You don’t want any pressure on it. You wash it just like a normal vinyl house, just bottom up. May take a couple of apps to get the darker stuff out, but shouldn’t be too big a headache.

I have a hard time correlating this to being washed just like a vinyl house. I’m probably over thinking it but I passed on the job. I’d like to find more info on Washing this then I was able to find on here, Facebook or YouTube.
