1. Can I use this on my granite paving to remove cement stains? Yes but not necessary as granite is not acid sensitive then our Stontex Cement Away would be a better stronger more effective solution. 2. I have efflorescence on my limestone cladding is this the best solution? Yes as limestone is sensitive then this is the safest product to use to remove this calcium buildup stain normally called efflorescence. 3. When my stone is clean should I seal it? Yes this would be recommended to make ongoing maintenance easier. Ask the Doctor for help and advice.
