Deos anyone have any ideas about how I can clean an interior brick floor? It used to be a patio that was later enclosed. There is drywall and woodwork so spraying with a garden hose is not an option.The brick itself is not that dirty, but the mortar joints are discolored and has some black spots. There is no finish on the bricks now but if I can get it clean enough I will seal it afterwards.
Thanks for any help

Just kidding.
Whatever you do, try a small inconspicuous area first and wait 24 hours before you go all the way.
A stiff brush and a diluted muriatic acid may be just what your mortar needs. Or regular bleach, especially if the black spots are mold or mildew. You will need to rinse well afterwards.
The acid may significantly change your brick (etch it) especially if they are concrete pavers. I suggest this only because I would guess you have tried mild soap and water.
