Are the tiles in your kitchen or bathroom not looking their best? If you've tried clean grout in between your tiles but not achieved good results, you may decide to improve their appearance by re-grouting them. The first step when you re-grout tiles is to remove the worn, stained grout already in place. You'll need an electric grout remover or a grout rake. An electric tool is easiest to use if you need to work on a large area, but a grout rake is a useful alternative if you are new to grout removal and prefer to work at a slower pace to gage results.
