Well I splurged this year on some pre-made chems instead of making my own. So I had to clean this pine wood siding on a store front for a friend - with tons of layers of loose layers of latex paint, never any prep. I took off the worst offenders with a turbo tip, but didn't go close enough to kill the wood. Then I used a pump sprayer and mixed efc-38 and 8 volumetric ozs. per gallon and soaked the siding. I have to say I was really impressed - with only 500psi, it took off years of greyed damaged wood and mildew leaving only clean wood behind.
This one lady, customer of my friend, came while I was working and wants me to estimate her natural cedar shaked home. She told me the story of how she is wildly allergic to a myriad of chems - and I gave her the whole spiel about landscape friendly cleaners, but she was persistant in her allergies. So I explained that this cleaner is the 'Evironmentally Friendly Cleaner' and she was like who cares what some manufacturer calls their products. Then I explained how it was mainly Hydrogen peroxide combined with soda ash and some phospate detergent builders. And her eyes lit up, she is harvard grad, and she instantly said she had no problems with hydrogen peroxide and knows about phosphate cleaners and has no probs with them either. And to boot she liked how I was using low pressure to clean the surface effectively. So we'll see.
