Tile – Best way to clean balcony tiles in semi enclosed balcony that doesn’t have drainage

cleaningtile

I have a first floor semi-enclosed balcony that is at the mercy of the elements. The tiles (porous stone) really need a good scrub with a water blaster but there is no drainage and I couldn't get a hose up there anyway. Any suggestions on the best way to clean it?

Some porous stone can be damaged by harsh cleaning chemicals. I would probably start with a stiff scrub brush on a broomstick, with a bucket of warm water and a bit of TSP (trisodium phosphate). Just don't use so much that you create standing water.

Let that dry then rinse with a sponge mop and clean water.
