I love the ones that ‘overpay’ you so you can pay their other providers and “keep the rest” - I actually had a guy who sent me a check for $2,500 (the work I was doing I priced at $350) and told me to pay for the carpenters that were doing work ($500) and just keep the rest. Dubloons is a great idea - I’ll ask for those next time 
Agree to do it, give the “carpenter” a check for $1000 if he’ll give you $400 cash…since the “carpenter” is the scammer anyway. He might just be greedy enough to fall for it.
So you would start at 8oz per gal and then downstream it? Wouldn’t that cut it super thin?
I have a deck that I’m looking at cleaning for a customer and it’s not super dirty. Thinking of using metasillacate followed up by oxalic acid. Probably could get away with DS house wash mix rather than using metasillacate.

I’ve been using Citric acid instead of oxalic. I did a cedar roof recently with percarbonate, 1000 psi rinse, citric at 8oz per gallon through the ar45, and final rinse. It looked like it brightened up like new after it all dried but then a month later I drove by and it was kind of gray again. Is that normal?
It’s wood - YES, unless you stain it.
New wood takes a year or two to go even a little gray. This seemed to go back way faster. I thought the brightening would last at least 6 months to a year. I was wrong lol
Not in my experience……stain or paint……if not it goes back to looking ugly.

Yes, I apply chems thin and then increase concentration as needed. The silver is from UV and no matter what you do it will go silver again and fast than it did when new. This is particularly true with horizontal or near horizontal (roofs) since they take a lot more abuse than vertical surfaces.
My chem recommendations are starting points. You have to make those decisions and test as needed to see if you get the results you want.

It does what you need on wood but it does not remove iron nail bleeds. I’d use it all the time if it remove iron stains.

Was a little bored one night earlier this month…scamming needs a higher barrier to entry, less people would do it. It’s worse than pressure washing, lol

These guys are idiots. They use the same name and same typos and even the same number but with different addresses. Here’s one I messed with a little while back

Do these clowns ever pick up the phone? Have you tried calling them to talk in person?
I got it! It reminded me of a scene from Taken with Liam Neeson when he meets Marco. I’m still laughing…
Never - they also seem to not want to give you an email address for some reason. (Even though they ALL seem to be gmail addresses.
Why on earth would I want to do that…?
