How to Wash a Caravan Properly (and How Often)

Washing a caravan isn't the same as washing a car. It's taller, the surfaces are different, and the wrong products can damage seals, decals and the gelcoat. Done right, a regular wash keeps the van looking new and stops small problems turning into expensive ones.

What you'll need

• A pH-neutral caravan or boat wash (not dishwashing liquid)
• A soft, long-handled brush and a microfibre wash mitt
• Two buckets, one for soapy water and one for rinsing
• A hose with a gentle spray nozzle
• A sturdy ladder or platform for the roof
• Microfibre drying towels or a squeegee for windows

Pressure washers can be used carefully on wheels and the chassis, but keep them well away from seals, decals, vents and window rubbers. High pressure forces water into places it shouldn't go.

Step by step

1. Pick the right time and place

Wash in the shade or early in the morning. Soap that dries in the sun leaves spots and streaks, and a hot surface makes it dry faster.

2. Start with the roof

Always work from the top down. The roof collects the most grime, and it's the source of most black streaks. Rinse it, wash it gently, and check seals and hatches while you're up there. Only stand on the roof if your manufacturer says it's rated for it.

3. Rinse the walls

A thorough rinse loosens dust and grit so you're not dragging it across the surface.

4. Wash one side at a time

Use the soft brush or mitt with plenty of soapy water, working top to bottom. Rinse the mitt in the clean bucket often. Pay attention to the areas under awning rails and windows where streaks form.

5. Treat black streaks separately

If normal washing doesn't shift them, use a dedicated black streak remover on a soft cloth. Avoid abrasive pads and solvents. Our guide to removing black streaks from a caravan covers this in detail.

6. Wheels, chassis and drawbar

Do these last with a separate brush so brake dust and road grime don't end up on the walls.

7. Rinse and dry

Rinse thoroughly from the top down, then dry with microfibre towels to avoid water spots, especially if you're on hard or bore water.

How often should you wash a caravan?

• After every trip. At least a good rinse, especially after coastal or dirt roads.
• Every 4 to 6 weeks in storage. A rinse stops dust and droppings building up on the roof.
• A full wash a few times a year, plus before long-term storage.

What to avoid

• Dishwashing liquid and household cleaners, which strip protection and dry out seals
• Abrasive pads, stiff brushes and cutting compounds on gelcoat
• Washing in full sun
• Automatic truck washes with harsh chemicals and spinning brushes

Make washing easier

If washing your van feels like a full day's work, a caravan ceramic coating changes that. Grime and streaks have far less to stick to, so most washes become a rinse and a quick wipe.

Common questions

Can I use a pressure washer on my caravan?

Carefully, on low pressure and from a distance, and never directly on seals, decals, vents or window rubbers.

What soap should I use to wash a caravan?

A pH-neutral caravan or boat wash. Avoid dishwashing liquid and household cleaners.

How do I clean the caravan roof safely?

Use a sturdy ladder or platform and a long-handled brush. Only stand on the roof if the manufacturer says it's rated for it.

Why does my caravan keep getting black streaks?

Grime collects on the roof and awning rails, then rain carries it down the walls. A coating stops it bonding to the surface.
