I'm sure you've all heard of the vinegar + blue Dawn super cleaner on Pinterest. If not, just search for those two words and you'll get a bazillion repins of the same few blogs. It sounds really great--just microwave 1 cup vinegar, add 1 cup blue Dawn, shake, and spray down your shower walls. What they failed to mention is that you may have a mild heart attack when you realize the blue Dawn is staining your bright white grout. Yes, instead of just "rinsing" with a sponge for a sparkling clean, I had to scrub every strip of grout with a bristle brush!
Now, I will not pretend like I usually am in charge of cleaning the bathroom. In fact, this is the first time I've cleaned it since we got married three years ago. But I am sure that the between the mixing, heating, spraying, soaking for one hour, plus scrubbing the grout while enduring the terrible odor is not any simpler than using good old Comet.
