Removing mortar haze , not grout on tile

Had dried mortar dust on towel when wiping down tile. Didn't realise it till already dry. Have about 6 18x24 tiles to clean, or replace.

What you have is lime haze (from the lime in the mortar) - the portland cement in the mortar would already be cured so would basically just act as a dust - not really stick as a haze.


If just a regular tub and tile cleaner will not remove it, use white vinegar on a rag - followed up immediately with wet sponge to remove the mild acid so it does not sit on and weaken the grout joints. Work small areas at a time - a couple to few feet square at a time, then wipe down with wet sponge.


And white vinegar - NOT brown - can stain the grout. And the white vinegar should NOT be balsalmic or olive oil derived or have any additives or seasoning (like many salad vinegars do) because they have oils which can stain - use a pure ethanol derived vinegar like Heinz White Vinegar.
