Limescale is a hard chalky deposit that is usually associated with pipework and appliances, however, it can occur almost anywhere; heritage buildings, factory walls, industrial unit cladding, flooring, urinals, swimming pools, washbasins, old bricks and more. Chemically, limescale is a deposit of calcium carbonate and is sometimes referred to simply as scale.
Removal of limescale can be a frustrating job, when you think that you have your limescale problem sorted, the surface that you have cleaned dries out and it reappears. The usual response to limescale cleaning is to reach for the acid to do the job. Domestic limescale removal is usually done using vinegar or lemon juice, but that is far too slow and inefficient for industrial limescale removal.
Industrial chemical removal of limescale is a hazardous task since it involves the use of hydrochloric acid (sometimes referred to by it old name of muriatic acid). Not only do you need to protect your staff from acid splashes, you need to exclude staff, visitors (and the general public in some cases) from the area being cleaned. Strong acids can easily damage the surface being cleaned, leading to expensive repairs. Then there is the small matter of the legal disposal of the acid too.
All in all, removing limescale build up requires planning and organisation that goes beyond normal industrial or commercial cleaning operations, in short you need a commercial cleaning contractor.
For external limescale removal, APT offer the best possible solution – soda blasting. Blasting soda is made from crystals of sodium bicarbonate that are designed to explode on impact. The energy of these explosions breaks down the bonds holding the limescale to the substrate, but without harming the surface below. It is therefore ideal for use on heritage brickwork, ancient and scheduled monuments, factory walls and cladding.
The reason that soda blasting does not harm the substance being cleaned is that it is very soft, when compared to building materials, ceramics, metals etc. It has the same hardness as talc and will not scratch or gouge the substrate.
Since it is the same material that is used in baking powder and some toothpastes, disposal is not a problem. You benefit from an easier, lower cost clean-up that will not contravene local or national environmental legislation.
