Paving slab stain

Goatz · Apr 25, 2020

Hi,

I have some strange staining on my patio concrete paving stones which I am struggling to get rid of. I have tried a jet washer which cleans up my other paving stones well but won’t clean these stains. I also tried pure bleach but no change.

any advice would be much appreciated.

p.s. the stones are about 10 years old.

thanks

It looks like staining coming through the slabs from below....if they're 10 years old they'll never get like new again as concrete is porous....the stain will be in them rather than on them.
