Key benefits
- Removes algae, green mould, lichen and black spot
- Restores sandstone coping stones

- Suitable for professional and DIY use
Suitable surfaces

Not suitable for: stained wood or decking, vinyl, plastic or metal (it may corrode metals). It contains chlorine and will stain fabrics and sensitive materials, and it may slightly lighten some surfaces.
How to use
- Wear chemical-resistant gloves and sealed safety goggles. Remove loose debris and pre-wet the area with clean water.
- Apply TM Algo Softwash generously and neat, using a pump-up sprayer or watering can. Take care to avoid fabrics and other sensitive surfaces.
- It starts working straight away. Agitating with the TileMaster 40 machine or a deck brush speeds things up.
- Wash the area down with clean water to neutralise the cleaner, then power wash with clean water and check the result.
- Apply a second time if needed. For severe black and white lichen, leave it to dwell for longer and power wash off the following day.
Take care around plants and ponds: the solution can harm or kill vegetation. Avoid washing it onto lawns and beds, or rinse with plenty of clean water if this cannot be avoided. Take extra care near fish ponds, and do not apply when rain is imminent.
Coverage and sizes
- Available sizes: 1 litre, 5 litres
Contains sodium hypochlorite and is corrosive. Store away from acids, and keep it out of drains, ponds and watercourses.
Always test on a small, inconspicuous area first. Read the product label and the Safety Data Sheet (SDS) before use.
