We do most of our cleaning with vinegar. We have a spray bottle of it in the kitchen and one of the bathrooms upstairs. I dilute it about half and half. I'll try to make a list here of the things we use it for. (It's late and I have pg brain so it probably won't be the complete list)
Clean mirrors and windows - with paper towels or a wet rag
Clean kitchen counters
Clean refrigerator - outside and inside
Clean bathroom vanities - spray on and wipe with a wet rag. If the sink is really bad, sprinkle on a little baking soda then spray with vinegar and wipe. When you spray the vinegar it will bubble so don't be alarmed. Also be sure you rinse well if you use baking soda because sometimes it can leave a powdery residue.
Clean toilet seats/tanks - I spray it on then use toilet paper to wipe everything off so I can just flush it then. This is one of my most impressive use of vinegar. My toilet seats sparkle, literally.
Clean chrome faucets and fixtures - makes them shine
Clean shower doors and walls. If you have hard water keep a spray bottle in the shower and spray the doors or shower curtain every day. (you don't need to rinse) It will keep them clean.
Clean car dash, windows, and mirrors. If you have tinted windows vinegar is safe.
Clean doorknobs and light switches - anything that get germs and handprints.
I also use it in the final rinse of the washer and I put it in my dishwasher where the jetdry goes.
Soak bright colored clothes in vinegar when they're new to prevent fading and bleeding.
Put a cup full of vinegar near the source of household smells to eliminate odors. Near the litter box or dog bed, bathroom, etc. Keep it out of reach. A decorative votive holder or something like that is great on a shelf in the bathroom.
If you have a dog or something that lays on furniture, LIGHTLY spray with vinegar solution to freshen and eliminate odors.
I know there's more but that's all I can think of now. Check out the book Vim and Vinegar and here's a great website.
