So, can you remove grout from tile? Yes, with the right tools, a little swearing, and a lot of grace for yourself. Go slow. Protect your surfaces. And remember: that grout isn’t a permanent life sentence. It’s just a crusty phase your floor is going through. You’ve got this. Now go make your tiles proud.
P.S. Have a glass of wine after. You’ve earned it. And maybe a dustpan. Definitely a dustpan.
