Whether it's vinegar and water as glass cleaner or baking soda and hydrogen peroxide as a drain cleaner, most of us have our own secret (or not so secret) homemade cleaning solutions.
In honor of spring and spring cleaning, we thought we'd start a list of good homemade cleaning ideas. Please add your own recipes and tips. With any luck this post will turn into a tremendous DIY/Natural Cleaning resource.
We'll start with a few of our own solutions as well as some we've gleaned from the comments section of other posts:
1. Sink: To clean our sink we like to make a paste of warm water and baking soda -- using the abrasive side of a sponge, stains cower before us
2. Drains: For cleaning out clogged drains: First, pour 1/2 cup of baking soda, follow with hydrogen peroxide and then cover.

3. Sink: I use hydrogen peroxide to help keep my kitchen sink extra clean and hopefully just a little more germ-free. After scrubbing it down with baking soda and rinsing, I give it a final spritz with the hydrogen p. All natural and super-cheap kitchen cleaning and disinfecting!

4. Wood: My favorite tip with lemons, combines pretty with practical. I take large glass containers and lay the full slice up against the glass. Fill with white vinegar. If you let this set, it makes the greatest smelling vinegar! Plus you have a pretty display for your counter top.
I like to mix the lemon vinegar with just a touch of olive oil to clean my woodwork. It also works great with baking soda to clean your kitchen drain! And smells heavenly!

5. Windows: I use vinegar to clean windows, but add a drop of liquid soap (Vermont Soap Company makes a great natural version) to really help cut down the streaks. Combine 2 cups of water, 1/4 cup of white distilled vinegar, and up to 1/2 teaspoon of liquid soap or detergent in a spray bottle - that's it!

Recipe: Spring Fruit and Nut Tabouli
Toilet-- Sprinkle inside the bowl with baking soda, let the soda set for a few minutes, then come back and spray with straight vinegar. Swish a toilet brush around, and you're good to go. This actually works much better than any store-bought product I've tried.
Air-- 2 T. Baking soda and 2 cups hot water combined in a spray bottle make an excellent odor neutralizer (and also helps keep fabric/carpet fresh). I also add essential oils to mine-- currently sweet orange and lavender. (The downside to this is that on hard floors you can sometimes feel the baking soda when it dries.)
I rub a rubbing-alcohol soaked cotton ball over my metal sink/shower handles and door knobs. It kills germs and gets rid of water marks/scum.
To clean my old porcelain bathtub, I sprinkle kosher salt into the tub, then rub the salt over the surface of the tub with the cut side of a cut lemon. The salt works as an abrasive and the lemon acts as a weak bleach. It smells divine!
I wouldn't try this with a fiberglass tub, though - the salt might scratch the fiberglass.
