Do you tell you customers what chemicals you are using ? i would worry that these chemicals are designed to be used inside a washing machine where they are thoroughly rinsed out but when wanding the same amount of rinsing may not be applied and you could be leaving a residue that leads to rapid resoiling, just seems to be penny pinching to save a tiny amount and even that is questionable whether you are in fact saving anything.
Why buy all these expensive chems?I use simply low odour white spirit mixed with hot water and mist over traffic areas etc.I use liquid detergent (as you would buy to wash your clothes) and put some fabric softener in to make it smell nice and it also stops any foaming issues.Rinsed out with hot clear water.I don't use anything else.I used to use what you guys use but I've now saved a fortune and have had no issues whatsoever. The carpets are def cleaner and they look great.
