First job done, need some newbie advice

Sodium Hydroxide can be found in most heavy degresers like purple power ETC... As far as the gum shadows, hit those with a light spray of fresh 12.5 sh and they should dissapear. No need to flood the area- Just a light coating.

Would I add the sodium hydroxide in with the rest of the mix or replace the chlorine? Time to go find out where I can get some.

I don't think you want to mix sodium hydroxide with chlorine, I'm not good with chemistry, but I believe this is a big no-no.

John I add it to my mix all the time as a degreaser along with my other surfactant to help break up grease and oil stains. I also add it to my roof mix when I've got alot of that orange mustard mold on the tiles.( not sure of the scientific name for it) It is the only thing that losens it up so that it will detach and rinse away. I've never had a problem using it this way. I'm not talking caustic beads, I'm talking about a liquid purple degreaser.
