1. Normal Soiling Carpet I prespray with DFC 210 16oz and rinse to specification the DFC 105.
2. Heavy Soiling, same DFC 210 boosted with 8 - 10 oz of sodium percarbonate, rinsed with DFC 105.
3. Upholstery Procyon Liquid
4. Tile/grout Procyon
5. Spotting is a different story and gets out of the green seal stuff and gets into the harsher stuff. If the normal prespray does not remove the stain, then use what works, if you think it will not be harmfull to the homeowner. If it's organic your good to go with peroxide spotting, but the synthetics is another story.
I have a water softner, and the above works great for me. Hope this helps
