Our kitchen grout was really dirty when we first bought our house
Pour some peroxide on the grout and let it sit for few mins
With a tooth brush scrub the grout lines. Peroxide action makes the dirt come out faster.
Use paper towels to clean the excess peroxide after scrubbing
Clean in 15 mins. Compare with the dirtier grout lines
Buy a grout sealer and seal the grout. Done.
