Simon,
Pure Clean
Multi-purpose carpet cleaning powder with new soap-free, enzyme-free and fragrance-free formula. Use in extraction, bonnet, spray cleaning and spotting for complete rinse and residue free cleaning. I have been banging on for years about how good Prochem Pure Clean is on carpets yet it has taken you till now to try it. At last you have seen the light.
Coyote,
Prochem Pure Clean is a really good all round performer on just about everything from suites to carpets. The only thing i seemed to have a problem cleaning when using Prochem Pure Clean is berber carpets (god knows why). Pure Clean works out really cheap to use unlike many of the liquid type micro splitters. In the past i have found that when using liquid type micro splitters that it can leave a white residue from over spray that i may have not wiped off.
It is advisable to have a range of chemicals on your van because there will be occasions that you find some wont work as well as others. As for which ones are best, this really will be a case of trial different ones. Prochem do have a superb range of chemicals. In addition to the chemicals that you currently use i would strong recommend that you also carry Pure Clean & Power Burst on your van. There are people that preach that detergent based chemicals leave a residue in the carpet, this is only the case if you fail to rinse extract the carpet correctly.
Chemicals such as M Power & Nemesis are like Marmite, you either love them or hate them, personally im still yet to see the WOW factor that some people rave on about with this type of chemical. I cleaned a night club for a friend the other week using M Power and yes it worked but to be honest the carpets in the club are cleaned every 5 or 6 weeks so id expect even cheap n cheerful pre sprays to work as the soil build up isnt on the carpet long enough to cause a problem.
Solutions UK do have 2 chemicals that im fond of using, RX Spotter is a good spotter and Fusion Clean for use with bonnet systems.
