Hi @Philmart 

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

Limestone is a porous material and bore water is high in minerals. Therefore, long term exposure of limestone to bore water creates limescale and mineral stains on the surface. I propose using CLR 750ml Ready To Use Calcium Lime Rust Remover in combination with Mr Clean Tuffmates Tile Scrub Brush. My best advice is to give the CLR enough time to activate before you start scrubbing and washing it off. Rinsing the surface too early will prevent the CLR from softening the mineral and lime deposits.

Please remember to wear personal protection such as gloves, goggles and a mask when working on your project.

If you need further assistance, please let us know.
