Have some off white tile that appears dull, probably because it's been stored in the garage for a number of years. Anyone have any ideas on how to get the shine back? Thanks

Magic erasers

Tile stripper from a commercial cleaning store. But first I'd use plain old white vinegar or even windex.

No I don't sorry

Try a hardware store

My first suggestion is don't go to floor and decor, the customer service sucks. The store is so short on staff good luck trying to find someone to help you.
