Extreme Clean Caravan & Motorhome Cleaner is a professional-grade exterior cleaner developed to remove stubborn road grime, black streaks, salt spray, and biological growth from caravans, campervans, and motorhomes without damaging delicate finishes. Its high-foaming, biodegradable surfactants lift traffic film and greasy deposits from GRP, gel-coat, painted aluminium, and plastic trims, while a powerful biocide package eradicates algae, mildew, and mould to leave a bright, hygienic surface ready for waxing or ceramic protection.

Unlike aggressive caustic detergents, this balanced pH formulation is safe on acrylic windows, vinyl graphics, rubber seals, and painted body panels. It rinses freely to a streak-free finish and contains no harsh solvents, making it ideal for routine washing, deep seasonal cleans, or trade valeting where consistent results and surface safety are critical.

Why Choose Extreme Clean Caravan & Motorhome Cleaner

This UK-manufactured cleaner is trusted by professional valeters and touring enthusiasts alike for its combination of powerful cleaning performance and material safety. Whether preparing a caravan for winter storage, refreshing a motorhome before a holiday, or maintaining trade stock for resale, it provides a fast, uniform finish with minimal effort and no risk of etching or fading.

Surface Preparation

Ensure the substrate is clean, dry, and free from grease, oil, dirt, rust, or loose paint. Degrease thoroughly and wire-brush or sand to remove all flaking material. Bare steel or heavily rusted areas should be cleaned to a sound surface before priming.

Priming

For bare or rusty steel, apply Extreme Paints Metal Oxide Primer to improve adhesion and provide enhanced anti-corrosion performance. Aluminium or galvanised substrates should be properly etched or primed to ensure a strong bond.

Mixing

Stir the paint thoroughly with a paddle mixer or paint stirrer for at least two minutes before application to ensure colour and resin are evenly dispersed.

First Coat

Apply a thin, even coat using a brush, short-nap roller, or airless spray. For spray application, use a 0.015–0.017″ tip and thin by up to 10% with white spirit if necessary. Avoid heavy application to prevent runs or sagging.

Second Coat

Once the first coat is dry (typically after 6–8 hours at 18 °C), apply a second coat at right angles to the first to achieve a film thickness of approximately 50 μm. This cross-directional application ensures full coverage, colour depth, and optimum protection.

Curing & Handling

Protect the freshly painted surface from rain or condensation for at least 24 hours. Light handling is possible after 24 hours, but allow a full 7-day cure before subjecting the surface to heavy use or chemical cleaning.

Clean-Up

Clean all brushes, rollers, and spray equipment immediately after use with white spirit or a recommended solvent-based thinner. Dispose of all waste responsibly in accordance with local environmental regulations.

Frequently Asked Questions

What surfaces can Machinery Enamel Paint be used on?

This enamel paint is versatile and suitable for metal, steel, galvanised iron (etched), timber, concrete, well-bonded existing coatings, and most porous masonry. It works well on machinery, construction equipment, skips, silos, and farm implements, providing a durable and glossy finish that resists wear and environmental exposure.

Can I use it on aluminium or galvanised surfaces?

Yes, but adhesion is improved when aluminium or galvanised surfaces are properly etched or primed with a suitable primer. This ensures the paint bonds fully and prevents peeling or flaking over time, especially in outdoor conditions.

How many coats are required?

For best results, two thin coats are recommended. The first coat creates a base layer and ensures adhesion, while the second coat builds up colour depth, durability, and a uniform, high-gloss finish that protects against corrosion and mechanical wear.

How long does it take to dry?

At 18 °C, the paint becomes touch dry within 6–8 hours. You can apply a second coat after 6–8 hours. Full curing, which gives maximum hardness and chemical resistance, takes around 7 days. Cooler or humid conditions may extend drying times.

Can I spray this paint?

Yes, the paint can be applied with a spray system. For airless spray, use a 0.015–0.017″ tip, or for conventional spray, thin up to 10% with white spirit if necessary. Spraying provides a smooth, even finish, especially for large metal surfaces or machinery.

Do I need to prime the surface?

Yes, priming is essential for bare or rusty steel using Extreme Paints Metal Oxide Primer. Aluminium or galvanised surfaces must be etched or treated with a suitable primer to ensure full adhesion and long-lasting protection, particularly in outdoor or high-humidity environments.

How do I clean tools?

Clean brushes, rollers, and spray equipment immediately after use with white spirit while the paint is still wet. This prevents the enamel from hardening on your tools and ensures they remain in good condition for future projects.

Is this paint UV and weather resistant?

Yes, the modified polyurethane resin ensures excellent weather resistance, protects against fading, and maintains gloss even under direct sunlight, rain, or frost. The coating is designed to flex with vibration and movement, making it ideal for machinery and outdoor metal structures.

Can it be used outdoors?

Absolutely. Machinery Enamel Paint is specifically formulated for outdoor use on farm equipment, construction plant, metal fabrications, silos, skips, and similar items. It resists corrosion, dirt, and cleaning with high-pressure water jets, making it ideal for heavy-duty external applications.

Are custom colours available?

Yes, for bulk orders of 100 L or more, BS 4800 or RAL custom colours can be supplied. This is useful for branding, machinery fleet consistency, or matching specific corporate or industrial colour schemes.

Is this paint flammable?

Yes, being a solvent-based enamel, it is flammable. Always apply in a well-ventilated area away from sparks, open flames, or other ignition sources. Follow safety guidance in the SDS, wear gloves and a respirator if spraying, and store safely.

How should I store this paint?

Store the paint in a cool, dry place between 5–30 °C. Keep containers tightly sealed and away from direct sunlight, heat sources, or children. Proper storage maintains product quality, consistency, and reduces the risk of accidents.

Can it resist oil and grease?

Yes, once cured, the enamel forms a tough, durable film that resists oil, grease, dirt, and cleaning agents. It’s particularly suited to machinery, workshops, and plant equipment where surfaces may encounter mechanical oils or fuel spills.

Can it be applied over existing coatings?

Yes, it can be applied over well-bonded existing paints or coatings, provided the surface is free from loose material, rust, or contamination. Surface preparation ensures proper adhesion, improves gloss, and prolongs the life of the coating.
