I love me some beautiful tile!
I hate to clean grout!
Many many moons ago
someone chose 1" square tile
for the floor of my shower!
It is gross 99.9% of the time.
I hate it! It never looks clean.
After hours of goggle-ing
the other day and lots of trial and error
the heavens parted and I found the answer!!
Sprinkle borax on the floor of a damp shower.
Let it sit.
Scrub it in and off an hour (or so later).
Ta da!! Clean floor!!
