Clean Tabs D Scale is an environmentally friendly, safe, and effective way to remove limescale and rust deposits and to clean the interior surfaces of hot water heaters, taps, pumps and interior surfaces of pipework in campervans, motorhomes, caravans or boats.

D Scale is non-corrosive and biodegradable, and can be safely used on Stainless Steel, Copper, Brass, Plastics and leaves no odour. Periodic use of D Scale in the water heater will avoid mineral deposits building up, so improving the efficiency and extending the life of the equipment.

D Scale contains citric acid which is a naturally occurring organic fruit acid especially found in fruits such as lemons and oranges. Calcium carbonate scale builds up layers and hard gritty deposits on the interior surfaces of a water heater.

When left without treatment, limescale deposits build up and will clog the interior pipes within the water heater, restricting flow and reducing operating efficiency.
