I clean some filthy office/warehouse carpets 6 times a year they are tight looped nylon needlepunch broadloom and similar carpet tiles, both are fully stuck down and are filthy. The carpets in places have oil walked on them together with occasional large water spillages which cause tide lines. I've been doing the work for years now and the client always pays and never complains but I am getting no satisfaction from the job as the carpets seldom look much better when I finish. HWE causes wick back and there is no air flow in closed off areas to dry them, Host just doesn't touh the soil, Dry Fusion is the best I've used but still not brilliant. On Saturday I spent ages with Micro Splitters and Super Pads but ended up going over it all again with Dry Fusion. What else can I try? I've never used Rotowash or similar, any advice? I suppose it would be easy to say that the carpets are beyond cleaning but if I didn't do it somebody else would and while the client continues to pay I want to do the best job I can.
I look forward to any suggestions.
