Hi folks, I have an off-white tile throughout my house which, for most purposes, is great. However, in the kitchen the same tile is not so user-friendly. It has a matt finish, is non-slippery, but has microscopic pits in it that accumulates dirt very easily. Washing only takes off the surface dirt; but it simply can't do a thorough job. If I spend a LONG time scrubbing with a floor cleaner, I can get the dirt out. What I'm looking for is a clear product (equivalent to a varnish) that I can apply (after thoroughly cleaning the tiles of course) that will soak into the tiles and fill those tiny pits, making future cleaning easier AND more effective. What would be the best product to buy, and does Bunnings have it? Many thanks as always, Orlando
