Take an empty spray bottle, fill it with about half a cup of dawn dish detergent, then fill the rest of the way with vinegar. Easy peasy, right?
I filled it about 2/3 with vinegar, then the rest water, since the dawn was ultra-concentrated. It also helped cut down on the vinegar-y smell.
Here's my bathroom sinks before:
And of course, the bathtub...don't judge me...remember I was pregnant and had surgery lol
I'm pretty sure I'll never buy bathroom cleaner again. This was super cheap and easy, and did an amazing job. The only slight complaint is that it smells like vinegar, but hey, bathroom cleaner doesn't smell like roses either!
