What grinder disc to use to clean tough stain on tiles?

[AJ-DIYer]

Hi

I have tough stains on my outdoor tiles including rust, old grout and timbre oil.

I have tried to use grout remover, vinegar, metal brush etc. They never worked.

I want to buy a metal disc to attach to grinder to remove the stains.

Is this possible? 

Would something like this work?

Hello @AJ-DIYer 

I don't recommend using the Josco 125mm Purple Multi Strip Disc as this will strip not only the dirt and stain but the glazing cover of the tiles. This will technically remove the protective cover of the tile, and it will become even more vulnerable to dirt and stains. I propose giving it one more try with either a Karcher SC1 Handheld White Steam Cleaner or a VAX Platinum Spot Wash Spot Cleaner VACSC21E. This is the next step up in regards to dirt and stain removal.

You can also try 30 Seconds 5L Outdoor Cleaner Concentrate or the CLR 750ml Ready To Use Calcium Lime Rust Remover on the tile surface. 

If you need further assistance, please let us know.
