[the red carpet]

hi all,
just read somwere that i should be using anti foam in the waste tank if i use a pre spray, is that right? as i have not been doing it, i get a small amount of foam at the top of the waste but only a very little bit.
i use alltecs citrus prespray.

Most pres-pays foam, if you use a rinse additive in the solution tank eg pro chem crystal green etc , them there is often sufficient foam suppression. However on excesssively soiled and greasy carpets a high ph traffic lane cleaner will need several applications and or rotary scrubbing. The additional airation will cause excessive foaming in the recovery tank. To collapse the foam a propretry defoamer should be added to the waste tank.

de foamer should be diluted & sucked through your vac hose into your waste tank.

Hi Red

The reason we use de-foamer, as I am sure you are already aware, is so the foam doesn't get sucked through the vac motors and make your machine go bang!.

Trick is not to let your waste tank fill up if you are using detergents or there is a residue in the carpet from previous cleans.

Yes, dilute and suck it up the pipe which coats the inside of the pipe as well as defoaming in the waste tank.  If you don't have a lot of foam in the tank then just put a measure in the waste tank.

I would recommend Prochems powdered defoamer, seems to go further than any liquid defoamer i have tried.

Best way to keep foam down is to use microsplitters!!
