Cleaning wall tile grout

square_bear

Hello all

Does anyone have a good effective method to clean wall tile grout?

My grout has become a dull grey colour now and I want it to become whiter again.

Thanks in advance to any replies.

I paint it with neat bleach, leave overnight and wipe the next day.. if it is really stained I use a toothbrush to scrub the bleach in..

best tip.. chisel it out and regrout with coloured grout (mine is grey in the kitchen with glitter mixed in)

Also if in kitchen and grout is therefore greasy toothbrush with bicarbonate of soda mixed to a paste with some water. Then wipe with damp cloth. helps to degrease them
Hope this helps

If you're going to the trouble of chiseling it out guys, can I recommend using epoxy grout to replace the cement grout?

Epoxy grout is waterproof, so it won't absorb stains or mildew in future.

The bleach method.


First I scrubbed with warm soapy water to get most of the lose stuff off, then painted thick bleach (neat) and left it on overnight.
In the morning I washed it all down.
