A natural and inexpensive degreaser is to keep white vinegar, water and perhaps a drop of dish detergent in a spray bottle. This is handy to keep in the kitchen but can be used in any room.
The best grease-cutting all purpose cleaner I have ever used is a mixture of water, a little bit of dish detergent (I use Dawn) and some vinegar in a spray bottle. This cuts through absolutely everything.
Baking soda and lemon juice works like baking soda and vinegar to do your drains. It's the same chemical reaction and it smells good. I discovered out of curiosity and a tree full of lemons.
I volunteer with a human society. I have been using their mixture of bleach and water to clean and disinfect the dog crates and kennels. I personally do no use bleach in my home life, and would like to know if there is a recipe that I could make to disinfect the kennels.
For inexpensive all purpose skin wipes, I fill plastic reusable baby wipe containers or (other plastic containers with lids) with a mixture of distilled water and a few drops of baby body wash. I then add a few paper towels or napkins to the mixture and place the containers in convenient places throughout my home.
If your cleaner doesn't have enough grit to it to do a good job quickly and easily enough, try adding a little table salt to it as you clean! I tried this today on my flat surface stove top, being out of my favorite regular brand, and it worked wonders !
