Our helper for stubborn lime scale or hard water deposits in bathrooms or toilets, when a fibre alone is not enough. Do not use on enamelled, marble or granite surfaces and avoid delicate bathroom fixtures. For treating small areas, apply a few drops directly to the surface to be treated, leave to act for a few minutes and then rinse with plenty of water. For larger surface areas, product can be diluted. Use a few drops in 250ml of water.
