Product for removing mould and mildew This product is especially suitable for cleaning the interior roof fabric. First, be sure to wipe the roof with a damp cloth so it is as clean as possible. Next, remove or cover furnishings and anything else in the awning. Spray the product directly onto the affected area and leave. It will dry within 1 hour. If this has removed the mould/mildew, the surface is ready for reproofing. If it has not completely gone, repeat the process. ISACLEAN ANTI-MOULD has a discolouring effect! It is advisable to wear work clothes or overalls to avoid damaging your clothes. Use this product only if/when other products do not achieve the desired result. This is a powerful product and is therefore tough on the materials, too. Accordingly, use it only when absolutely necessary.
