Always pressure wash after short trips.
Just finished an 8 week trip that included red dust and sand.
Everything emptied out of every storage nook and cranny, vacuumed, stainless steel bits cleaned and polished, canvas brushed down and bird droppings hand scrubbed and removed. Then the real work began.
Wheels off, pressure washed, truck wash used, another pressure wash, rust and stain remover (diluted phosphoric acid) used on all gal surfaces, pressure washed again. Finally hand washed and polished, tyre shine on tyres and mud flaps and black plasticy bits.
Kamper looks great and is ready for another adventure. I don't consider myself anal, rather a good clean is part of the ongoing maintenance of the Kamper.
