How to Clean Your Caravan or Motorhome: The Complete ValetPRO Guide

The ultimate step-by-step guide to preparing, washing, and protecting your camper — ready for the road in no time.

Cleaning a caravan or motorhome is no small feat. With more surface area than a family car, a complex mix of panels, rubber seals, plastic trim, and glass, and the added challenge of months of outdoor storage, it’s easy to see why so many owners put it off. But with the right products and a smart method, you can get your camper looking immaculate — without spending your whole weekend doing it.

Whether you’re bringing your motorhome out of winter storage or maintaining it throughout the season, this guide walks you through the ValetPRO professional approach: prewash, wash, and long-lasting protection.

Why a Proper Cleaning Routine Matters for Your Caravan

A motorhome or caravan is a significant investment, and neglecting its exterior maintenance can lead to some expensive problems down the line. Green algae, black streaks, traffic film, and road grime don’t just look unsightly — left untreated, they can:

• Degrade rubber seals and cause water ingress
• Permanently stain GRP (glass-reinforced plastic) and painted panels
• Trap moisture that leads to surface oxidation and dull paintwork
• Make future cleaning far more difficult and time-consuming

The good news? A three-step routine using ValetPRO’s purpose-formulated products makes light work of even the most neglected camper.

Step 1: Tackle Built-Up Grime with ValetPRO Citrus Prewash

Best for: Post-winter storage, heavy contamination, green algae, road film

If your caravan has been sitting in storage over winter, the first thing you’ll notice is a layer of green algae, biological growth, and general grime that a standard wash simply won’t shift. This is where ValetPRO’s Citrus Prewash earns its place as the essential first step.

Formulated with powerful citrus-based cleaning agents, Citrus Prewash is designed to penetrate and break down heavy organic soiling — including the stubborn green algae that colonises caravan roofs and sidewalls during damp storage. It works by chemically loosening contamination from the surface before you even pick up a brush or sponge, dramatically reducing the risk of scratching delicate GRP or painted panels.

How to use ValetPRO Citrus Prewash on your caravan:

1. Dilute to suit the task — Citrus Prewash is a concentrated formula, so you can adjust the dilution ratio depending on how heavy the soiling is. For winter grime and green algae, use at a stronger concentration.
2. Apply to a dry or damp surface — Work in sections from the top down. Spray generously across the roof, sidewalls, and any heavily soiled areas.
3. Allow to dwell — Give the product 3–5 minutes to penetrate and lift the grime. You’ll often see it begin to emulsify the soiling.
4. Agitate if needed — For particularly stubborn algae, a soft brush or detailing mitt will help. Avoid heavy scrubbing on glossy panels.
5. Rinse thoroughly — Use a pressure washer or hose to rinse away all loosened contamination before moving to the wash stage.

Pro tip: Pay particular attention to the roof and lower sills — these are the areas most prone to algae and green growth, especially after winter storage in a damp environment.

Step 2: Deep Clean with ValetPRO Concentrated Car Wash

Best for: The main wash stage on all caravan and motorhome surfaces

Once the heavy soiling has been lifted by the prewash, it’s time for the main wash. ValetPRO’s Concentrated Car Wash is a premium pH-neutral shampoo that delivers a deep, lubricating clean without stripping any existing protection from your panels.

Highly concentrated, a small amount goes a long way — making it excellent value for the large surface areas typical of caravans and motorhomes. Its rich, thick lather clings to vertical surfaces, giving the formula time to work on remaining dirt and grime, while its gentle formula is completely safe on GRP, painted panels, plastic trim, rubber seals, and glass.

Why Concentrated Car Wash is ideal for caravans:

• pH neutral formula — won’t degrade rubber seals or plastic trims
• High lubricity — reduces the risk of marring or scratching delicate surfaces during contact washing
• Rinses cleanly — leaves no residue or streaks, ideal for the large panel surfaces of motorhomes
• Concentrated value — covers more vehicle for your money, important given the size of most caravans

How to wash your caravan:

1. Prepare two buckets — one with your Concentrated Car Wash solution, one with clean rinse water. This two-bucket method keeps your wash mitt clean and prevents swirl marks.
2. Work from the top down — start with the roof and work your way down to the lower panels and sills.
3. Use a soft wash mitt or sponge — avoid abrasive materials that could scratch GRP or painted surfaces.
4. Rinse frequently — rinse your mitt in the clean water bucket before reloading with shampoo solution.
5. Final rinse — rinse the entire vehicle from top to bottom, ensuring all shampoo is removed.

Step 3: Protect with ValetPRO Snow Seal — Spray On, Rinse Off

Best for: Long-lasting protection, easier future cleaning, hydrophobic finish

This is the step that transforms your cleaning routine going forward. ValetPRO Snow Seal is an incredibly easy-to-use spray-on, rinse-off sealant that bonds to exterior surfaces, creating a durable hydrophobic barrier that repels water, dirt, and grime.

The beauty of Snow Seal lies in its simplicity: apply it to wet panels after washing, leave it briefly to bond, then rinse off. No buffing, no polishing, no complicated application — just outstanding protection that makes every future wash faster and more effective.

The benefits of Snow Seal for caravans and motorhomes:

• Hydrophobic water beading — water sheets off the surface rather than sitting and drying, significantly reducing water spotting and mineral deposits
• Dirt and grime resistance — the protective layer means contaminants struggle to bond to the surface, making them easier to rinse away
• Reduces algae re-growth — by creating a smoother, more protected surface, Snow Seal makes it harder for biological matter like algae and mould to take hold during storage
• Easier maintenance washes — with Snow Seal in place, your next wash requires far less effort and product to achieve the same result
• Safe on all surfaces — suitable for GRP, painted panels, plastic trim, glass, and rubber

How to apply Snow Seal to your caravan:

1. Apply to wet, freshly washed panels — after your final rinse from the wash stage, leave the surface wet.
2. Spray Snow Seal evenly — work in sections, applying a uniform coating across each panel.
3. Leave briefly to bond — allow the product a short dwell time of around 1–2 minutes.
4. Rinse off thoroughly — a clean rinse with a hose or pressure washer removes the carrier, leaving the protective sealant bonded to the surface.
5. Allow to dry — the hydrophobic protection activates as the surface dries.

Pro tip: Apply Snow Seal at the end of each full wash to maintain the protective layer throughout the season. Regular top-ups mean you’ll spend far less time and effort keeping your caravan clean.
