What is the best way to clean stained grout between the floor tiles?

Non bleach tile and bath cleaner!

I picked up this tip and it has been so easy and successful . Use toilet bowl clinging gel and pour it on the grout. Leave for 20 mins. Sometimes you might need to scrub loose the dirt with a toothbrush. Rinse clean. Great smell too .

These are some good ideas for cleaning grout. The suggestion is to use milder cleaning solutions first. Super strong cleaning solutions can eat up your grout. https://www.google.com/amp/s/amp.realsimple.com/home-organizing/how-to-clean-grout%3fsource=dam

Home Depot has grout paint. It's easy but tedious.

The best way is the contact a steam cleaning company and have them steam the group. Another idea is make a paste with baking soda ad peroxide and clean the grout with a toothbrush.

Hi Phyllis, You can make a thin paste of hydrogen peroxide and baking soda. Apply it to the grout and let it sit for about 10-15 minutes. Scrub with an old toothbrush and rinse clean. If the grout between the tiles has worn down too far, it may be a better idea to first re-grout and then seal. You can also buy grout pens to quickly “recolor” your grout and make them look new again.

I used Barkeeper's Friend and a toothbrush to clean my kitchen grout. I used Maipei grout paint to change the color of the bathroom grout. It was an easy and amazing change!
