Did the generic bleach show the percentage concentration of acid? The generic bleach that was left by the contractor didn't list the concentration (about 15 bottles). It hardly had any smell and i'm real sensitive to the smell of bleach. Though it was about 6 months old.
I'm using 10% pool chlorinating "bleach" by Pool Essentials from Walmart for $3.64 a gallon, 10% sodium hypochlorite concentration. Probably about the same price that I can get the 3 packs of Clorox bleach from Sam's Club or Costso, which are a bit smaller (121 oz) and have a lower concentration (8.3%). Think i will use this to clean the cedar fence too.
