Hi,
Last week we were asked to clean a hand made, 100% wool rug that was predominantly white with a lot of coloured areas. There was a large number of oil spots and a patch of irn bru staining that we didnt think we could shift. So we took it offsite and pondered on the best way to clean it.
We spotted the oil with solvent, and sprayed the entire rug with MS, agitated it to within an inch of its life then HWE. >> it looked a bit better, but nowhere near clean. So we let it dry and evaluated our results

We then proceeded to dry foam shampoo it with prochems fibre shampoo by making some foam in a bucket then working it with a sponge. It took about 12hrs to dry before we vacuumed it. >> The rug was clean and our client amazed.
Until this point, we had never even thought of dry foam shampooing anything, but it seems a pretty solid cleaning method. I was most impressed with the feel of the rug after cleaning. Each fibre felt much softer and the rug had a nice shine to it.
It is now my most favourite low moisture method as it beats wearing a respirator and slopping around bucket loads of chlorinated slovents.
Hope this helps,
Graeme
