A clean caravan isn’t just about looks. Regular cleaning prevents mould, extends your van’s lifespan, and keeps your mobile home feeling fresh during those long months on the road. After hundreds of thousands of kilometres and countless campsite setups, we’ve learned the most efficient way to tackle both interior and exterior cleaning without wasting precious time or water.
This guide covers the complete process from pre-wash prep to final protective treatments. You’ll learn the specific products that work best in Australia’s harsh conditions, the order that prevents you from doing work twice, and the maintenance schedule that keeps your van in top condition.
1. Gather Your Cleaning Supplies
Having the right supplies makes cleaning faster and prevents damage to your van’s surfaces. You’ll need different products for different materials, and quality matters when you’re dealing with expensive caravan components.
Essential Cleaning Products
- Exterior wash: Caravan-specific detergent (not household detergent)
- Interior surfaces: Multi-surface cleaner safe for plastics and fabrics
- Windows: Streak-free glass cleaner
- Upholstery: Fabric cleaner or leather conditioner
- Mould prevention: Vinegar solution or anti-mould spray
- Protective treatments: Carnauba wax or polymer sealant

Tools and Equipment
- Two buckets (wash and rinse)
- Microfibre wash mitts (3-4 pieces)
- Soft-bristled brush for stubborn dirt
- Squeegee for windows
- Microfibre drying towels
- Vacuum cleaner with crevice tool
- Extension pole for roof cleaning
Use separate wash mitts for different areas: one for the body, one for wheels and lower panels, and one for the roof. This prevents transferring grit and grime to clean surfaces.
2. Prepare Your Caravan for Cleaning
Proper preparation prevents water damage and makes the actual cleaning much more efficient. This step is particularly important for caravans with slide-outs or external storage compartments.
Interior Preparation
- Remove all loose items from surfaces and storage areas
- Open windows and roof vents for ventilation
- Turn off 12V power at the battery isolator
- Remove or secure loose cushions and bedding
- Check that all external hatches and vents are properly sealed
Exterior Preparation
- Retract awnings and ensure they’re properly stowed
- Close all external storage compartments
- Remove or cover the electric brake controller and Anderson plug
- Check jockey wheel and stabiliser legs are wound up
- Position the van in shade if possible
Never clean a hot caravan in direct sunlight. The cleaning products will dry too quickly, leaving streaks and potentially damaging the surface. Early morning or late afternoon are ideal times.
3. Clean the Exterior
Start with the exterior while you have the most energy and motivation. The process follows a top-to-bottom approach to prevent dirty water from running onto areas you’ve already cleaned.
Rinse and Pre-Wash
Begin with a thorough rinse to remove loose dirt and debris. Use a gentle spray setting to avoid forcing water into seals and joints. Pay particular attention to areas where road grime accumulates: wheel wells, lower panels, and behind external storage doors.
Apply your caravan wash solution using the two-bucket method. Fill one bucket with soapy water and keep the second filled with clean rinse water. This prevents you from putting dirt back onto the van’s surface.
Wash the Roof First
The roof collects the most debris and requires the most attention. Use an extension pole with a soft brush attachment to avoid climbing on the roof unnecessarily. Work in small sections, keeping the surface wet to prevent soap from drying.
Clean around roof-mounted solar panels, air conditioners, and antennas carefully. These areas trap dirt and debris, and the fittings can be damaged by excessive pressure.
Body Panels and Windows
Work your way down the sides, washing one panel at a time. Use straight, overlapping strokes rather than circular motions to avoid swirl marks. Rinse each section before moving to the next to prevent soap from drying on the surface.
Clean windows with a separate microfibre cloth and glass cleaner after washing. A squeegee gives the best streak-free results, working from top to bottom in overlapping strokes.
Lower Panels and Wheels
The dirtiest areas come last. Lower panels, wheel wells, and the drawbar area typically need a brush and extra attention. Use a separate wash mitt for these areas to avoid transferring grime to the clean upper sections.

4. Clean the Interior
Interior cleaning requires attention to different surfaces and materials. Work systematically to avoid missing areas and prevent cleaning products from damaging sensitive surfaces like electronics or leather upholstery.
Vacuum First
Remove all loose dirt, crumbs, and debris before applying any cleaning products. Use the crevice tool around cupboard edges, seat cushions, and in corners where dirt accumulates. Don’t forget to vacuum inside cupboards and storage areas where dust settles.
Remove seat cushions and clean underneath. This area often harbours surprising amounts of debris and is easily forgotten during regular cleaning.
Kitchen and Bathroom Areas
These areas require the most attention due to grease, soap residue, and potential mould growth. Start with the kitchen, cleaning from top to bottom: light fittings, cupboard fronts, benchtops, and finally the floor.
In the bathroom, pay special attention to corners and joints where mould can develop. Use a vinegar solution or commercial anti-mould spray in these areas. Clean the shower screen, toilet, and vanity thoroughly, ensuring you get into all the corners.
Remove the shower head and tap aerators every few months for a thorough clean. Mineral buildup from bore water can significantly reduce water pressure over time.
Living Areas
Clean all surfaces including cupboard fronts, light switches, handles, and window sills. These high-touch areas harbour the most germs and show dirt quickly. Use appropriate products for each surface type: plastic cleaner for laminate surfaces, leather conditioner for leather upholstery, and fabric cleaner for cloth furnishings.
Don’t forget the ceiling and walls, which can accumulate cooking residue and dust over time. A slightly damp microfibre cloth works well for most caravan interior surfaces.
Windows and Ventilation
Clean interior windows with glass cleaner and a lint-free cloth. Open roof vents and Fantastic fans need regular cleaning to maintain proper ventilation. Remove the covers if possible and clean both the fan blades and housing.
5. Final Inspection and Protection
A thorough final inspection ensures you haven’t missed any areas and helps you identify any maintenance issues that need attention. This is also the time to apply protective treatments that will make future cleaning easier.
Exterior Protection
Apply a quality carnauba wax or polymer sealant to the clean, dry exterior surfaces. This protection lasts 3-6 months and makes future cleaning much easier by preventing dirt from bonding to the surface.
Work in small sections, applying the product thinly and evenly. Remove according to the manufacturer’s instructions, typically after it hazes over. Don’t apply wax to rubber seals or textured surfaces where it can be difficult to remove.

Interior Final Touches
Replace cushions and bedding once surfaces are completely dry. Apply fabric protection spray to upholstery to resist future stains and make cleaning easier. Ensure all vents remain open until the interior is completely dry to prevent mould growth.
Check that all electrical connections are dry and secure before reconnecting 12V power. Test lights, fans, and other electrical components to ensure no water damage occurred during cleaning.
Seal and Joint Inspection
Use this opportunity to inspect all seals around windows, doors, hatches, and roof-mounted equipment. Look for cracking, shrinkage, or areas where the seal has pulled away from the surface. Address any issues immediately to prevent water ingress.
Common Cleaning Mistakes to Avoid
These mistakes can damage your caravan or make cleaning less effective. Learn from others’ experiences to avoid costly repairs or time-wasting efforts.
Using the Wrong Products
Household detergents are too harsh for caravan surfaces and can strip protective coatings or damage decals. Similarly, using car wash products designed for metal vehicles can harm fibreglass surfaces. Always use products specifically designed for caravans or RVs.
Cleaning in Direct Sunlight
Hot surfaces cause cleaning products to dry too quickly, leaving streaks and potentially causing damage. The rapid evaporation also means you’re working harder to achieve poorer results. Always clean in shade or during cooler parts of the day.
Neglecting Regular Maintenance
Leaving cleaning until the van is heavily soiled makes the job much harder and can lead to permanent staining or damage. A light clean every 2-3 weeks on the road, with a thorough clean monthly, keeps maintenance manageable.
Never use high-pressure washers close to seals, vents, or electrical connections. The pressure can force water into areas where it shouldn’t go, causing expensive damage that may not be apparent for weeks or months.
Forgetting Interior Ventilation
Insufficient ventilation during and after cleaning can lead to condensation problems and mould growth. Always ensure adequate airflow during cleaning and leave vents open until everything is completely dry.
- Clean systematically from top to bottom, exterior first then interior, to avoid re-contaminating cleaned areas
- Use caravan-specific products and avoid harsh household detergents that can damage surfaces
- Always work in shade and ensure proper ventilation to prevent streaking and mould growth
- Apply protective treatments after cleaning to make future maintenance easier and extend your van’s lifespan
- Regular light cleaning every 2-3 weeks prevents heavy buildup and makes deep cleans more manageable
- Inspect seals and joints during every clean to catch potential problems before they become expensive repairs
