Knowing Your Stone: Siliceous vs Calcareous
Siliceous and Calcareous Stones
Avoid causing damage to popular natural stones such as marble, travertine and limestone by understanding key differences between a siliceous and calcareous stone.
Common types of siliceous stone include: granite, slate, sandstone, quartzite, brownstone, and bluestone. A siliceous stone is composed mainly of silica or quartz-like particles, and are considered durable and easy to clean. Unlike a calcareous stone.
For siliceous stones, messes such as hard water stains and mineral deposits are easier to clean, since it is safe to use "mild" acidic cleaning solutions on an occasional and infrequent basis. Although harsher products should still be avoided, products such as the Scum & Mineral Deposit Remover may be used.
Common types of calcareous stones include: marble, travertine, limestone, and onyx. Calcareous stones are composed mainly of calcium carbonate, which is sensitive to acidic or alkaline-containing substances. As a result, these stones require various types of cleaning methods for various types of messes, particularly for messes such as hard water stains and mineral deposits.
For calcareous stones, acidic cleaners or products such as vinegar and lemon juice should be avoided. Additionally, formulas designed for removing calcium should be avoided, meaning the Scum & Mineral Remover should not be used. In these cases, protective or preventative formulas are recommended. For this case, ioSeal can be greatly beneficial.
