clothes are greasy/grimy. hands are too. fast orange works great on hands.
anybody wash clothes in fast orange (or something like it)? I imagine it would take too much fast orange to be effective - so probably a need very high fast-orange to water ratio, i.e. 10 times more fast orange volume than is normally used of simple laundry detergent.
otherwise, I imagine it should be OK in the septic as long as the pumice versions are not used.
