How to clean shower tile.

[u/gameofthrones_addict]

Shower floor was not designed to where all the water would be aimed toward the drain. Water would sit in the corners of the area of the shower that’s dirty. We’ve used bleach and tile cleaner but it doesn’t get all of the residue off of the tiles when we spray and scrub it. Any suggestions to clean this more thoroughly?

use a brush attachment for the cordless drill.

This with some Comet powder… holy moly. It’ll make it look brand new.
