I have the inner roof or headliner out of my B3000. I am wondering if anyone has found a good way to clean it. Mine's not too bad but could use a good clean.
I have had a lot of success cleaning roof liner, seats and carpets using a shop vac. For the carpets, I use a pressure washer first then immediately suck up the water using the shop vac.
Keeping the level of moisture under control and, after the shop vac, leave item cleaned in the open for any remaining moisture to evaporate.
In reality it is like a heavy duty carpet cleaning machine.
A mild detergent and soft scrub brush helps in heavily encrusted spots on the seat or carpet.
My ceiling has stains from opening soft drink cans.
