Cleaning solution on the plastics, borax/FelsNaptha scrub on the floors and cloth seats, followed by a hot water extraction using a Mr. Clean solution.
The wife wasn’t happy with the condition of the bed. Dull, faded, marked and scratched bedliner.
So I cleaned it up and sprayed a coat of Rustoleum Truck Bed protector. Night and day difference. $6 and the bed looks great.
