Firstly, we would recommend pressure washing the surface to remove the marks. If this does not remove the marks, then we would recommend using an outdoor porcelain tail cleaner - floorseal.co.uk/product/outdoor-porcelain-tile-cleaner/
@@Ovaeda hello thanks for your swift response. Yes I have already tried the jet washing a few times. It lifts a little bit of the chalk up but not the worst of it. It’s gone yellow in some parts. I’ll definitely try the product. Thanks
I have a build up of rain water on one side and it’s left a white (chalky?) stain. How is best to remove this?
