Your house wash mix should work just fine.

My guess would be the surface was oxidized before you started. I have quoted jobs then got the call to do the job. When I get there I realize the home was a little more chaulky than I remembered or more plants to move ect... The only other suggestion would be your mix was to strong or left a little to long. It does sound like you must brush.

What is a surfactant to use with caustic soda or oxalic acid?

Might consider the cost of a lift. You usually have to be close to the surface. I personally don't do them because of the cost required. Keep us informed.

Did alot of the finish wash off as you were cleaning? Possible oxidation problem.

I know I'm fixin to stank things up. But, just want to converse not condem. I had a pt deck to clean. First time in 20 years it had been cleaned. I provided two prices. One for a bleach solution one time only process and a two step process. Tried for a got the two step process I used 8 oz of F18 per gallon and downstreamed waited and cleaned. Then 8oz oxalic and a rinse. The next day I was not happy. I DS'ed 16oz per gallon caustic soda and 16oz per gallon of ox. This process brought more money and more work. Did not seem to be any easier. Maybe I should have mixed stronger the first time. I cleaned the steps to lake with bleach and they cleaned up well. I want to properly clean wood but must offer a lower priced process to compete with others.

How did you price the job you have coming up? Most people usually ask what the price will be in advance. You will know for sure when you are finished if you were profitable or not.

Almost a dollar a sq.ft. for the deck is hard to get for just cleaning where I live.

I may have missed it. What is your product? Homes ,Roofs......

There are some true professionals on this site and you have been addressed by some of the best. Not having your signature on your post causes problems. You fixed that. You will need a pressure washer, a downstream injector that can pull your chems through at least 150' of hose. and the proper tips for your machine. You mentioned Bob, good move. If you are going to do anybody else's house other than your's you should consider insurance. Good luck.

That is a shame. I learned alot and enjoyed meeting everyone. I know from helping organize State Championship for sporting clays how much effort is involved. Russ, you need help. We should organize a group of people to represent Alabama. Meet, Plan,Organize. I personally would not need the cookout at the park, or the country music singer. I will help you any way I can. I will be glad to drive over to help. You need to tighten your ass up. What happened to going big?
