cleaning tiled floor

Alkaline floor cleaner. Caustic contents, removes worn-in greasy grime with little scrubbing...

Thomas Prufer

Bleach or Jeyes fluid, or if it's cooking grease, ammonia or caustic.

But wear butyl gloves and eye protection, preferably a face shield.

The stuff sold as oven cleaner may be close enough to work. Again be very careful - it is capable of inflicted very serious chemical burns on exposed skin or blindness if used carelessly. Try it on a small patch.

Left on too long aggressive alkaline cleaners can damage glazed tiles.

Try washing soda before you get too medieval on its arse.

Bleach and a scrubbing brush. And huge amounts of elbow grease

Use gloves and a knee pad

Then a squeege mop and lots of water.

open the windows.

I'd try standard bathroom 'cream cleaner' first, as used on baths and hand basins, before moving up to more aggressive cleaners if that doesn't work.

Depends on the tiles. The old quarry tiles are the same material through and through. Cheap modern tiles are glazed, when the glaze wears off muck gets into the material below depending on porousity. You can buy stuff to apply to the tiles once cleaned to prevent/reduce this. Doesn't last as long as the g;aze though.

Ceramic Tiles covers a whole range of finishes and materials- glazed, unglazed, porous etc. Some even have a waxy finish, at least when first laid etc. ( or should have). The first task is to decide what you have, then you can research the best methods.

Having said that, I?d tackle any particular stains first- perhaps where things have been spilled over the years, before tackling the overall area.

If they are porous, I?d reseal them. Again how/ what with depends on the material.

I assume they are quality tiles you want to preserve, the last thing you want is to make things worse.
