How to remove calcium stain from concrete pavers?
Hello @jocelyne
Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about removing calcium stains on pavers.
I propose looking at using CLR 750ml Ready To Use Calcium Lime Rust Remover in combination with an Oates Compact Deck Scrub Brush. If you have a pressure washer, I suggest using it to rinse the surface of the concrete paver. I suggest doing a quick test on one of the pavers to see its effect, if you are satisfied with its performance, you can then commit the entire area.
If you have any other questions we can help with, please let us know.
