No salts, gentle, compatible media

This product is also known as Crushed Limestone and classified as a soft media.  We usually recommend using this media for stone and masonry cleaning and restoration projects.  Because Calcium Carbonate contains no salts, it won’t trigger or cause any type of efflorescence reaction.  It’s the best choice for building materials like granite, marble, masonry, brick, and limestone, as its chemical structure is identical to them, making it completely compatible with these substrates.


Many ESCA-supplied projects have used Calcium Carbonate for sandblasting successfully – its soft nature won’t harm delicate surfaces and will remove most soiling conditions such as carbon deposits, atmospheric pollution, and soot. It is totally landscape and operator-safe, rinses away very easily, and has a proven track record. We consider this media “architect-approved”! Its recognized by many historic preservation professionals and conservators as a way to perform “do no harm” cleaning in a safe and consistent manner.
