RV and Fleet Detailing and Reconditioning

Those streaks are oxidized EPDM roof membrane that rain carried down the sidewall, and ordinary soap does nothing to them. Removal requires a dedicated streak remover with mechanical agitation, and on badly neglected coaches it takes compounding. The long term fix is addressing the roof, either by recoating the membrane or by cleaning it on a regular interval, because as long as the membrane is chalking the streaks will keep coming back.

Not at high pressure, and this is where most detailing damage happens. High pressure lifts EPDM seams and drives water past sealant that was doing its job perfectly well beforehand. Harsh alkaline cleaners degrade the membrane and accelerate chalking. We clean roofs at low pressure with membrane appropriate products, and we inspect every penetration while up there, which often catches a sealant about to fail.

Yes, and it is a safety item rather than a cosmetic one. Oxidized lenses scatter light and substantially reduce usable output, which matters on a vehicle that is long, heavy and slow to stop. Proper restoration means wet sanding through progressive grits, polishing, and applying an ultraviolet protective coating. That final coating is what most cheap restorations skip, and without it the lens re oxidizes within about a year.

It is one of the few vehicle expenditures that reliably returns more than it costs. A coach presented with streak free sidewalls, restored headlights and a genuinely clean interior sells faster and for meaningfully more, because buyers read presentation as an indicator of how the whole vehicle was maintained. For fleets, reconditioning at turn in protects residual value and reduces end of lease charges, and we batch that work so the whole fleet is not down at once.
