I think we've pretty well hijacked it already, sorry OP

Maybe your MF (it's a waffle weave type, right?) needs to be washed really well and rinsed with white vinegar in the rinse cycle to remove soap, sealant or wax buildup. I try to wash my WW drying towels separate from polish or wax removal towels to avoid contaminating them and reducing their absorbancy.

Thanks, I'll get some big waffle weave MF towels (which I don't have), will follow your other advice, and turn this thread back over to the foam gun topic!

Thanks,
Richard
