Soap isn't only used for getting clean.
Here are 20+ other uses for our soap
Lubricate nails, screws, and saw blades: Soap on metal helps it go through wood more easily. Nails and screws go in easier and are less less likely to split the wood if they are first stuck in a bar of soap. Rubbing soap over a handsaw blade will help it cut straighter and be less resistant to the wood.
Keep your fingernails clean: While you’re working in the garden or potting plants, scrape your fingernails over a bar of soap to collect slivers underneath them. This will prevent dirt from caking under your nails and the soap washes out easily.
Keep bugs off plants: Soap works as an insect repellent and can protect your plants from being eaten by bugs. Mix soap with water until it’s sudsy, then put the water solution in a bottle and spray the underside of plant leaves.
Relieve itchy bug bites: Rub the bites with a dampened bar of soap for instant itch relief. It also helps keep the bites clean.
