Notes
Mix the peroxide paste fresh; don’t store it. Safety: skip chlorine bleach, it can permanently discolor grout and tile. Also: never mix vinegar and bleach; don’t use vinegar on natural stone (marble, travertine) or unsealed grout often; wear gloves; peroxide can lighten colored grout, test first.
