The President of the company I work at asked me to give him a quote to clean the building I said great. He meant inside out. I thought about for most the day and declined. Too much involved I told him and too many liabilities. Well we agreed to me working on company time and he would rent my equipment. I took him up on in and here are some results from the today. Also what would clean the exterior of the tin outside? I’ve tried a house wash mix, degreaser, dg/hw, the algae died but it had a slight film still. It’s a Fab shop I’m quoting the outside of it. The last two are what the outside looks like. Any good chems to kill that?
