Caravans are an incredible way to embrace the great outdoors, offering freedom, flexibility, and a home-away-from-home. But over time, unsightly moss, algae, and lichen creep in to the picture, especially on roofs, seals, awnings, and exterior panels. If left untreated, these invaders not only ruin the appearance of your caravan but can also cause long-term surface damage.
Luckily, our comprehensive range of high-performance cleaning products are specially formulated to tackle moss and algae build-up with ease. In this guide, we’ll cover what causes growth on your caravan, the key problem areas, and the best products to restore your caravan to its pristine condition - safely and effectively.
Where Moss and Algae Love to Grow
- Roof Surfaces
The roof of your caravan is the most common hotspot for moss and algae. Its flat or gently sloped surface allows rainwater to collect or only drain very slowly, especially around vents and skylights. Combined with sunlight exposure, this creates a warm, damp environment perfect for organic growth. Factors like falling leaves, shaded parking spots, and frequent rainfall make it nearly impossible to avoid roof contamination. That’s why regular cleaning and treatment are essential.
- Seals and Rubber Trims
Rubber seals and trims retain moisture longer than smooth panels and are often packed with tiny crevices that trap dirt and spores. With condensation, dew, and poor airflow, these hidden areas become a breeding ground for moss, algae, and mildew. What’s worse, this build-up can degrade the plastic and rubber over time, leading to costly replacements that can be so easily avoided with routine maintenance and targeted cleaning.
- Awning Rails and Roof Edges
Often shaded by awnings or overhangs, these areas stay damp for longer periods. Dirt accumulation and limited sunlight create ideal conditions for mould, algae, and lichen to thrive. These edge zones are frequently overlooked but can rapidly degrade your caravan’s finish if left untreated.
- Underside and Wheel Arches
Hidden from sight and exposed to road grime, mud, and splashback - the underside of your caravan is a silent victim of algae and mildew. Without sunlight or airflow, moisture lingers, allowing bio-growth to fester. Neglecting these areas can result in weakened flooring, warping, and even structural cracking - problems that are expensive and difficult to fix. Regular inspection and preventative treatment are key.
Best Products for Moss, Algae, and Lichen Removal
- Baticlean CR
Baticlean CR is a high-performance, powerful pH-neutral moss and algae remover that is trusted around the world. Perfect for caravans, it works on a variety of surfaces - plastic, metal, rubber, and more. Just spray it onto a dry surface and leave it to work. No rinsing needed!
One application lasts between 9 to 18 months, making it a top choice for long-term caravan care. It’s also eco-aware: while powerful against moss, small overspray won’t harm surrounding plants or grass.
For best results, we recommend
brushing away heavy build-up beforehand to ensure as much product has contact with the surface as possible, then applying with a sprayer from our
professional-grade range to ensure ease and simplicity. After spraying, simply let it dry and work its magic - with no rinsing required, it's raved about for its efficiency, especially when paired with our
sprayer accessories.
- Baticlean ECR
Prefer a more environmentally responsible solution? Baticlean ECR is part of our ECO-Responsibility line and so is free from chlorine, acids, and other harsh chemicals. It’s safe to use on fiberglass, aluminium, glass, plastic - virtually all caravan surfaces.
This concentrated formula should be diluted with water at a 1:9 ratio before use. Once
sprayed, allow it to dry - still no rinsing needed. Just one litre of ECR covers up to 100 square metres, making it an economical choice for ongoing caravan maintenance.
