Franklin Cleaning Technology Formula 900 Soap Scum Remover, Liquid, 1 gal. Bottle

I bought this from the advise of previous rating. I used as directed. it was pretty good. I used everything you could think of. Vinegar, cooking spray, bleach, wonder eraser etc. They all worked but to a minimum. I have a acrylic shower enclosure ad have worn off finish trying to get it clean. This is what I did and it cleaned like a boss!! Fill a spray bottle with the full concentration. Wet shower area to be cleaned. Spray on areas to be cleaned. Scrub for a few minutes and you'll see the grim coming out. I recommend this product!! it's worth every penny. I had my doubts when I received this blackened bottle covered with dust and dirt. Not a hot seller I thought... Don't judge a bottle by the outside!!
