I mix percarb a little strong and either DS or Xjet it. Never had an issue with it not working fast enough. On a deck where I'm going to use percarb, I love inviting the HO to watch me clean. I like to turn customrers into company cheerleaders by showing them the percarb process in particular.
FYI: After it fizzes out, percarb leaves behind water, hodrogen peroxide and sodium carbonate (water softener salt). Nothing else.
