Today I washed and waxed the painted and chromed surfaces and applied "Aerospace Protectant 303" to the assorted rubber and vinyl bits.
I never use high pressure water and usually end up giving it more of a sponge bath with distilled water than a drenched bath with (our hard) tap water.
Except for a small area where the paint is slightly chipped she looks like new.
