Any help or suggestions would be great. I just came home from a job "cleaning" cgd in a small town cafe. The carpet is about a year old, cinnamon colored, extremely soiled and I couldn't get this carpet even close to clean to save my life. I've been in the business 2 years, use a Prochem Apex truckmount, presprayed 4 different cleaners (a general olefin cleaner, a peroxide cleaner, a carpet spotter, and a citrus cleaner), rotary scrubbed, extracted ...and nothin. I bet it didn't even look 10% better. Even if there are better cleaners out there this carpet should have at least looked like someone did something. The only time it looked better is when I actually got down on my hands and knees and manually scrubbed a few of the 200-300 spots. Has anyone encountered this kind of issue before? Needless to say I was plenty embarrassed and stumped when I left. What could I have done different? Is there something about cgd I obviously don't no or is this just "one of those jobs"? HELPPPP! Thanks for any info.
