What are these black spots/stains? Is it tannin or old residue from a previous stain? How do I remove?
Story: Deck was originally stripped with Behr deck stripper, result was what you see here. Then did test spot with Cabot deck stripper with no visual difference and then Defy OxyBleach...
I have a couple of cases of Sodium Hypochlorite (Austin's - Pool Tech Pool Shock) that I had in storage over the winter (Pittsburgh...saw freezing temps). Will it still be good for use? How can I test the potency?
Thanks!
