How to remove stains from pavers

Question

I have a client with peacock pavers. They had a large mat in front of their door with two planters on either side if it. The planters leaked onto the mat and drained off the porch, but the dye from the mat has left a bad stain on the pavers. Any recommendations on how to pull those stains out?

Answer

2019-20 NTCA Reference Manual

I would contact a company that makes sealers, grouts, and related products and ask them if they have a product that will work to dissolve the minerals that leached in from the planters. Some setting material manufacturers also make products like these. If you know which company made the grout and/or thin-set, they would be the logical choice to ask first.

Do you have a copy of the NTCA Reference Manual? In the manual, there is a section dedicated to processes to remove stains from tile and stone. A quick browse through the table of contents will point you to this section that will provide tips and tricks that may help remove stains like these.
