Restoring tiled porch flooring

Mizydoscape

Today I've uncovered this lovely tiling in the porch of the Edwardian terraced house we moved to back at the end of September. It was hidden under 4(!) layers of lino.

I would like to know how is best to go about cleaning and restoring this. Would it benefit from a sealant of some description?

Thank you

It looks like the tiles are all undamaged?  If so, I'd start by cleaning it up with some warm soapy water to get the worst of the muck off. Wait for it to dry completely, then attack any sticky residue with meths on an old cloth - this is great for dissolving grease and old adhesive.  As long as the grouting is undamaged, it shouldn't really need any further sealing - but it'll be well worth replacing any grout that is damaged, to prevent water finding its way underneath.

One small tile is damaged. It's a small chip out of the corner but this looks to have been filled with grout. The grout appears to be in good condition.

There also appears to be a crack or two in the thin cream tiles. Nothing to worry about - I would say that the floor has lasted very well considering the age. Many would have been ripped out by now and replaced with concrete.

Give it a good wash, and preserve it for future generations.
