Plastic razor blades are used a lot by auto and boat detailers because they won't scratch surfaces. I use them all the time for scrapping old stickers, decals and even some paint from tiles, they are fabulous. It can be hard to find them so I have arranged to buy from the manufacturer and resell them. I know you are going to love them for tiles and a lot more. I use them on my glass stove top too!

Package contains 10 blades only
