Does anyone know how to remove old grout from indoor floor tiles. I want to re-grout but as its a 2 bed apartment I don't want to have to start scraping the old out by hand

Any info would be gladly received

does it actually need replacing, or does it just look grubby?

all the spanish cleaners I know just bleach them - obviously not if they're marble though!!!


I know a good floor restorer guy if you need one

Unfortunately it needs replacing. We tried bleaching last year ans within no time at all it looked horrible again. I have with tiles and white grout. Want to put grey grout in now

If the tiles are not marble, then try using 'salfumant' - this is basically a mild acid
(IIRC).

Being acid, it will eat the grout but not the tiles - you may find this cleans them enough.

Thank you,

Salfumant that's what I was trying to remember
Do I leave it on for any particular length of time them just wash it off. Or, will I still need to clean the joints with some kind of too

The longer you leave it on, the more it 'eats' the grout. You may need to get an old (flathead) screwdriver in there to gouge out some of the grout.
