Dremel MM500 1/8-Inch Multi-Max Carbide Grout Blade

Used to do one floor and it was knackered out after about 80 of the job

Es durable y lo utilizo para quitar lechada vieja de loseta.

Genial super 👍

...and does the job. I have to stress out that, as other folks mentioned, you will have to apply a lot of elbow grease to make things happen - it won't do it by itself. Also, it does work MUCH better on the sanded grout. I had both types of the grout in my bathrooms and really felt the difference. I would strongly advise to start in the middle of the tile and continue along the middle line through the whole row (vertically or horizontally) and then, do the same, but a bit closer to the edge of the tiles. It worked quite effectively and it minimizes the chance of scratching or damaging tiles. Don't force it - just let it go.Be ready to see a lot of VERY fine dust (decent mask and closed field goggles A MUST!) and NOISE (!) (make sure to take care of your ear drums - use either earmuffs or earplugs). Don't vacuum right away! Vacuum exhaust can blow this fine dust to "high heaven" and deteriorate the situation. Try to wipe the dust first and collect as much as possible into the plastic bag with wet paper towel. Vacuum afterwards and try to keep vacuum's exhaust outside the room.

Works very good for grout cleaning.
