There are tons of different cleaners out there that can be used. There are also solutions that you can make at home. One of them is a simple mixture of water, baking soda, lemon juice, and white vinegar.
-If you are looking for a store bought cleaner just make sure to read the back of it as some of them will have a strong acid base within them that will cause you to have to reseal your grout. Also be careful if you choose an acid cleaner as if there is any splashing onto your stainless steel appliances it will remove the finish on them.
