Hi guys,
Had an enquiry off facebook today, it's slighty outside our normal work, ie its indoors!
Here is the message, if you need more info let me know and I'll try to get it
They have used brick acid, so it maybe too late !!
We recently had our kitchen done by some not so professional builders, one of the things that went wrong was when they were laying beige/sand colour floor tiles, they left the charcoal coloured grout on too long and it's left alot of residue on the tops of the tiles. We've tried a little with brick acid to rectify, but just me and a kitchen scourer. Is there anything more you can think of to rectify this?
Thx
Darran
