For most of my adult life, glass shower doors have been the bane of my domestic existence. We live in an area with very hard water, and we have a water softener, but if the salt runs out, the water runs hard. I also don't think the water softener does its job all the way. I can remove soap scum from the glass shower doors, but the little bitty hard water drops (you know what I mean, if you struggle with this) were impenetrable by even the most obnoxious cleaner--Scrubbing Bubbles. I always try to use homemade and nontoxic cleaners, but nothing seemed to touch my shower doors.
Recently I saw a recommendation for dawn + vinegar, so I tried it yesterday. It works! I used an entire quart jar of homemade cleaner on our basement shower doors (I just poured, splashed, and scrubbed it on) but now that I know this works, I'm going to invest in a high-quality spray bottle for this stuff. Next time I won't use an entire batch, either--this will be a great maintenance cleaner.
Here's the method:
*Heat 2 c. vinegar in a microwave-safe container (or you can heat it on the stovetop). I heated it for about 2 minutes.
*Pour this into a jar, spray bottle, or squirt bottle, and then add 1 c. blue Dawn dish soap. (Some recipes call for a 1:1 ratio, but you don't need that much!)
*Shake. Then spray/pour/squirt onto your shower doors. I let the solution sit there for a few minutes while I did other things, and then I went back to start rinsing and wiping it off.
It worked great! I had to scrub a bit here and there (the worst spots were at the bottom of the doors), but many of them just sort of disappeared without any scrubbing at all. I had to do a lot of rinsing with clean water because the Dawn makes things very sudsy and slippery--I just used a clean bucket of water and a cup to pour all over the shower doors. It was messy but I was working with what I had!
And now I go into the bathroom to look at the doors whereas before I avoided that bathroom because of the doors. So, there you go!
