Hi. Just finishing installing Spanish tiles with uneven, non-glazed surfaces. Normal grout removal with float left grout in the little recesses, some of which has now dried. It is a lot of work removing with water and Brillo pads. Someone has suggested using nail polish remover to soften the grout. I've tried it on a small patch and it seems to work. Has anyone had any experience with this? Or does anyone have a better idea? Many thanks.

I cannot for the life of me think why nail polish remover would soften grout!!! The only explanation I can think of is the acetone in the nail polish remover is attacking the additive if it were a flexible grout.

The best way in my opinion to remove grout is to use a product that attacks the cement particles such as Aqua Mix Phosphoric Acid or Grout Haze Clean Up if its light residue or there is a product out there that Lithofin do called cement away I think

I agree, acid based remover is the quickest way to go.

Be careful not to get the acid on any anything metal near by as it will most likely effect the finish

Thanks. I'll try it.
