(BTW, cleaners and cleaning is one of the MANY topics I cover in my minimalist book, Minimalist Monday: Declutter Your Way to a Zen Home, which you can pre-order here.)
This all-in-one bathroom cleaner really does the trick AND it only takes a couple of products you probably already have sitting around the house.
Here's what you'll need:
-1 Professional Spray Bottle
-8 oz. Distilled White Vinegar
-4 oz. Lemon Juice
-2 oz. Liquid Soap (I use an eco-brand from Whole Foods Market)
-2 tsp. Baking Soda
-10 oz water
Add the baking soda and vinegar FIRST and let it fizzle out before adding the rest of the ingredients (it will foam if you don't). Add the remaining ingredients, squeeze out the suds, screw on your cap and you're ready to clean!
Clear all surfaces, then spray down everything (sink, counter, mirror, tub, toilet, etc.) Let it sit for a few minutes before wiping it down with a cloth. Don't forget to rinse out the tub so it isn't slippery!
For really stubborn stains, spray down the area with extra bathroom cleaner, then use a sponge (be sure it's one with a non-scratch scrubber) in a circular motion. Rinse thoroughly and your stains should be gone! (Source)
