It is essential that you understand which stones can be treated with acidic products in order to remove rust and which cannot. Read the following, call us if there are any queries and make sure you do small test areas. This is YOUR responsibility. 

Some stones such as granite, slate and sandstones can become discoloured due to a natural iron content oxidising (Rusting). This can cause brown marks or, in the case of grey or black granite, dark patches.

A common cause of this issue being rapid and / or severe is the use of hydrochloric acid contained in brick and patio cleaners. Never use these products on natural stone.

Another common cause of small, brown rust marks is the use of lawn feed and weed type products. These contain ferrous sulphate which can cause marks; do not leave the pellets on your stone!

Rust stains can be caused by rusty water running off iron or steel tools or fixtures that are oxidising (Rusting). 

Initially, on acid resistant stones such as most sandstone, most granite and most slate use Builderase. Test small areas first.
