as per jason, on organic stains and on carpets that are not actually minging, it does a great job...
doesnt waste time for me, as i will vac, spray,agitate, then allow dwell whilst i a) set up my machine, or b) prep next room,
no wasted time, just a good return on chemical investment due to the dilution rate!!!! i do understand that for some folks tghis type of chemical hasnt worked, but there you go, it works for me and i think bioclean is particularly good..... mpower was okay as well.....
on filthy carpets i would use different chemicals accordingly.............
