How to clean mortar off bluestone?

mitchlc

I have mortar staining on my bluestone pavers which I didn't think was an issue at the time I laid them, but apparently you can't use hydrochloric acid on bluestone... I've tried soapy water and a nylon brush but the staining won't go away. Any ideas how to remove this without damaging the bluestone? Thanks

Hello @mitchlc 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about removing mortar stains. 

I suggest giving Chemtech 1L Brick Tile And Paver Cleaner a try and see if it will lift off the mortar stain on your pavers. Please remember that this is a concentrate and must be diluted before use. I recommend testing a small section first just to make sure that its compatible with your paver. I don't recommend using hydrochloric acid as it will damage your pavers surface.
