10 Best Algae Remover

The Wet & Forget Mould, Lichen & Algae Remover is a versatile and user-friendly solution for those looking to clean outdoor surfaces without extensive effort. It effectively targets mould, mildew, and algae, making it suitable for a variety of surfaces such as roofs, patios, driveways, and even solar panels. One of its key strengths is its large coverage area; a single 5-litre container can be diluted to create up to 30 litres of solution, covering approximately 100-300 square meters. This makes it a cost-effective option for treating extensive contamination.

The formula is bleach-free and biodegradable, adding a layer of safety for users and the environment. However, users are still advised to wear protective gloves and eye protection during application, which could be seen as a minor inconvenience. Another notable feature is its ease of use—simply spray the solution and leave it; no scrubbing is required. It is important to ensure that there's no rain for at least 5 hours after application for optimal effectiveness. The product is unscented, which could be a pro or con depending on user preference. One potential drawback is that the effectiveness may vary depending on the severity of the contamination and the type of surface.

This product is ideal for those seeking a hassle-free, environmentally friendly algae remover for various outdoor surfaces.

The Jarder Spray & Leave algae remover is a strong concentrate designed to clean green mould and algae on many outdoor hard surfaces such as patios, decking, fences, driveways, and even UPVC windows. Its main draw is ease of use — you simply dilute, spray, and let it work without scrubbing or pressure washing, which saves effort and time. It contains 50% more active ingredient than many comparable products, making it quite effective for large areas (up to 240m² per bottle). Results usually appear in 2-3 days, and it creates an invisible barrier that can help prevent algae regrowth for up to six months.

Safety-wise, it’s non-caustic, free from acid and bleach, and considered safe for children and pets once the treated area dries, which is reassuring for typical home use. However, since it works by spraying and leaving it to act naturally, it won’t provide immediate visual results and might not be suitable if you need quick cleaning. Also, while it’s compatible with a wide range of surfaces, care should still be taken with delicate materials.

This product is suitable for homeowners seeking a convenient, effective, and long-lasting algae remover that requires minimal physical effort.

The Wet & Walk Away Organic Moss & Algae Remover is a liquid solution that works by drying out moss, algae, mould, and lichen, making them easy to brush or blow away without scrubbing. It is suitable for a wide range of outdoor surfaces including patios, Indian sandstone, driveways, decking, astroturf, and bricks, covering up to 100m² in total. This product is praised for being pet safe, biodegradable, and free from harsh chemicals like acids and bleach, making it a thoughtful choice if you have pets or want an eco-friendly option. Its active ingredient is ethanoic acid, which effectively inhibits moss and algae regrowth for up to 9 to 12 months, depending on your local climate.

Application is straightforward: you spray it on dry surfaces when the weather is clear, and there's no need to rinse or scrub, which saves time and effort. However, it may require multiple applications over several months if the moss or algae infestation is heavy, especially in damp or rainy areas common in the UK. Users should also avoid applying it when rain is expected within 48 hours to ensure it works properly. While the product is ready to use and comes with trigger sprayers, the coverage per litre is about 10m², so larger areas will need more product.

Some customers note it works better on warm, sunny days and might take longer to see results in cooler or cloudy weather. This remover is a safe, environmentally conscious option that effectively cleans and brightens outdoor spaces, particularly if you prefer to avoid strong chemicals and manual scrubbing, but patience and correct weather conditions are key for best results.
