How to clean bed-liner?
 

I have a spray in liner(not sure of the brand, came on the truck) and I hauled an old rusty barrel to the dump and it got rust marks all over the liner. I figured they would wash off but I can't get them off?

I just scrub mine with whatever kind of car wash soap or spray cleaner I have out at the time and a stiff bristled brush.

^Try the bristled brush,

Or a pressure washer with some soap.

pressure washer and simple green or purple clean

Alright thanks, will try!

yea, once in a while while at the coin op, just scrub with the brush and rinse it off.
