Pool Deck Stains

[mobileoneservices 14]

I have a customer with a new pool, less than 12 months old. The oak trees seem to be dropping debris and staining the concrete. I washed it today with a commercial concrete cleaner with no luck. Also tried wood brightener and had no luck. Any ideas on how to remove these stains? I'm trying to avoid any muriatic acid due to the damaging effects it has on the concrete.

Thanks,

Scott

Sodium hypochlorite.... Bleach.

Don't even consider muriatic on it. Search oxalic and find all your answers.

What Michael said. Bleach will work.

Guys, thanks for the help. I worked on the pool deck today and tried Oxalic, bleach and a few other things, and nothing. Thanks for the ideas, this one has me frustrated.

Scott do not use muriatic acid on that because the risk is to great. You can carve(etch) that concrete like a Christmas tree if your not careful. Is that a salt water or chlorinated water pool? If it's just the typical chlorinated pool did you try doing a spot with liquid(chlorine) which is 2.5x the strength of regular bleach? I'm only saying this because if it's a regular pool they shock them with liquid Chlorine. If your saying bleach and Oxilic acid is't working then you can step it up a notch with liquid chlorine which won't hurt the pool if it gets in there..

I can't tell with my I Pad but is that like tree sap or just stains on the concrete?

First of all, are you using cold water or hot water? If you are using cold, try hot.

Second of all, add some degreaser to that bleach, in other words try it as a house wash mix. After cleaning then apply some oxalic. Then rinse. We get stains like that out of concrete all the time.

Tannin stains on concrete equals bleach( what mike said). On wood acid will remove them.
