Question

Anyone found the best way to clean a tile floor the the grout is black?

Answer 1

I would recommend some professional strength grout cleaner and brush to use. Home remedies rarely work.

Answer 2

they sell grout tools at lowes. it is like a shinny metal with a bunch of little metal shavings on it. You will need to take your time and just scrape til you see new grout. you will have to reseal it after you finish. Good luck.

Answer 3

Use white vinegar and a brush.........slow but worth it......dry well.......

Answer 4

I got good results with 2 parts hot water to 1 part white vinegar + a few drops of dish soap per gallon.

Spread on grout, scrub with grout brush, mop up with clean mixture. I use 2 buckets - 1 with cleaning solution, the other has hot water for rinsing the mop.
