Using sulphamic acid, Limescale Remover DS-3 is a powerful but environmentally friendly product which is ideal for use to remove baked-on limescale deposits from domestic appliances and boiler heat exchangers. Designed with the consumer in mind, the product is safe and easy to use; after each application the product changes colour to indicate when DS-3 is exhausted and ready for disposal to foul drain.

Fernox DS-3 is used for removing limescale from any type of water heater to restore its efficiency. It is safe to use with steel, stainless steel, cast iron, copper, brass, PVC, ABS rubber polythene and most plastic pipework.

Limitations: It should not be used with thin gauge or badly corroded aluminium, zinc, galvanised steel, acrylic (e.g. plastic kettles and baths) chromium plated or enamelled surfaces (e.g. baths), concrete and asbestos. When in doubt, check with the appliance manufacturer.
