Author: Linda This size will do a very dirty shower a couple of times. Here are the steps I use: You need to make sure you use gloves. Use a small bottle with a single hole or a spray (harder on the hands to keep squirting) and start at the top. Do an area about 2 feet across all the way down: apply product then use a stiff bristle brush to spread. Allow to foam first if white. Rinse from the top several times and wipe dry with a towel. Make sure the section you do next is not really wet. It works better when tile is dry.
I purchased Ed Fred tile cleaner from a Ace hardware here in Mesa, AZ. a few years ago to clean the water stains from my cut glass goblets, but in doing so, I found the best scum remover ever!
At the store where I work we had some water sprinklers that were hitting some black tinted windows. Over time they were messy white encrusted windows baked in the AZ sun.
I took my bottle of Ed Fred where my manager sparingly used what was left in the bottle, and got them shiny black again.
