You need a grout residue remover, i use the one that LTP do availiblle from tile giant,mae sure you do a test area first

i thought it might be something simple ! just wasnt sure due to it being porlin !

after the fact, but always best to make sure it's cleaned off properly before it sets:8:

Make sure you dont get any on the grout as it will discolour

I can't speak for the LTP product, but the H&G version doesn't discolour the grout. A test are should show whether this will happen or not, but i don't think it's supposed to.

Just checked what brand it was and you were right Beanz it was LTP

I would use Aqua mix sealer & coating remover, if its a real problem to remove.

lithofin cement away can also be used, watered down at first and up the concentration if need be!

Ltp actually will reverse any bleaching caused by other residue removers, i did not believe this myself at the time their rep informed me of this, but seeing was believing, and it does work.

good suggestion but the sealing & coating will bust down the polymers then you need some phos acid as well
