Outer Limits 4x4 Board

Hey guys i just bought an '02 Lux and the sillls and chassis have dirt through them what is the best way of getting rid of it?
Cheers Jai

Pull out the plastic plugs along the length of the chassis, and get in there with a Gurni.

As for the sills, same story, get under the cab, pull out the blanking grommets, use a piece of wire to clean out the drain holes and lots of gurni action

I dunno if you have the facilities, but steam can work wonders on a dried muddy underside.
