This comes up so many times builders using brick acid on Limestone FFS, post a photo so I can see the damage, but it may need replacing sorry, brick acid & Limestone don't mix, will they never learn!!!

or just about any natural stone for that matter

Cement and Limestone have similar chemical makeup so any chemical designed to remove cement will do plenty of damage to Limestone also

We do a Mortar Stain Remover but do not recommend it on Limestone for that very reason http://www.azpects.co.uk/product....er.aspx
