I totally agree Barry. We are being charged for water.

Glass cleaner is the biggest rip off. Usually 95% water and most still don't clean well, eg Windex.
Having problems with windows? Try this simple solution. Water wet a MF and wring it out. Lightly mist the cloth with a degreaser or ONR and scrub the window. Remove with a lint free MF or paper towel (Bounty). Rub until water is gone. Also a lot safer than breathing in chemicals.

My dilution rates of degreaser are 4:1 engine, 25:1 interior-carpet spotting.

Carpet pretreat 40:1, extractor 120:1.
