Use dye-free cleaners to avoid staining your tiles or grout
When cleaning backsplashes, you might want the tiles and the grouts to stay the color they originally were. It would not do to go clean them and have whatever product you use stain them an unsightly shade of blue or orange. That is why it is always a good idea to use items that are dye-free.
If your bathroom has natural stone tiles, you should be extra careful to not spill anything with color since it is a particularly absorbent material. To be sure that your cleaner will not stain, you can try buying a product that is specially formulated to clean grouts or tiles. It is also a good idea to avoid using any household products like vinegar on delicate surfaces.
