The rugs?
What are they made from?
I doubt the Hydroforce that is in the picture should be a part of the process
She bought the rubber backed rugs from Cost Plus in 2003, she wasn't going to pay much of anything so "just make them better" was my (free) task at hand.
Hosed them down with LST and 40vol, and wand rinsed with 4.5 Saigerinse.
Tossed them in the yard on a rock bed to dry.
That nubby rock had berber is impossible to get a tight seal on but 300 PSI and 3+ dry strokes latter it looks much better.
Last ti9me Padded it which didnt do much.
