- plain water
- white vinegar (or apple cider vinegar if you really hate the aroma of regular vinegar)
- a drop or two of dishwashing liquid soap
Use about 1 part vinegar to 2 or 3 parts plain tap water, adding a drop or two of dishwashing liquid soap. (For washing dishes in the sink, not dishwasher detergent.) Shake it all together in a clean plastic bottle with a spray attachment. Use to clean just about everything!
