Tried my Gallon of fission on 5 houses yesterday, lots of different soiling from heavy to not-so-bad.
Used it at 6oz/gallon and allowed at least 10 minutes of dwell time and FWR.
Did several "Trashed" rooms with half Judson O2 (@ 3oz gallon no hot sauce added)
and the other half with Fission,
The Judson side left the carpet slightly cleaner, but noticeably brighter and softer.
The Fission side was not as clean and dull looking. And I had to work a little harder.
I am going to clean a few commercial properties this weekend and give it my final review.
