The problem is with the grout. Originally it was probably sealed.
Over many years, the sealer has deteriorated. It is kind of scaling
off and does not look so good any more.

So, I would like to remove all remnants of the original sealer, then
scrub the grout free of accumulated grime and then apply a new
sealer. I can remove the old sealer pretty well with a brass bush, which
does not scratch the tiles. However, it is hard work and I am tired
of it. Is there a mechanical scrubber that will take the hard work out
of
refurbishing my grout?

What do the pros use? I am sure they do not do it with a small brass
toothbrush.


If it were me, I'd use acid. One *does* need to know how to use it
though,
Ever do it? Acid will damage tile if the tile has metallic (coloring)
glaze.

Yeah, I've done it. First time some 50+ years ago was sort of an
error...rented apartment, really dirty white grout on the shower floor tile.
My intention was to remove part and redo; acid was too strong, ate it all
out. No big problem, just needed more grout than I had planned for.

And no, I wouldn't use it on anything that the acid could damage other than
the grout.
