I like you do for Duration of cleaning instead of Concentration of cleaner.
- I rinse.
- 1 Scoop of Oxyclean But I use COOL water
- Sit 24 hours
- Rinse witrh HOT water
- when time to use Rinse again with hot StarSan
The reason I use cool water is because I read that some this type of cleaner (Percarbonate) can leave a film (crystalize) if the concentration is t0o high in the same way you get water drops from hard water.
So by using a lower concentration and cool water I avoid that.
The double Rinse with HOT water insures there is no cleaner left around to screw up your beer.
I think I read this in John Palmers Book "How to Brew" but I am unsure...
