Easy DIY is so right up my alley. This is one of those no-brainer choices...
Foaming hand soap is so much more fun than regular hand soap. But it can cost like $3 to $5 a bottle! So here's an easy DIY:
Take an old but clean foaming hand soap bottle and fill it almost to the top with water. (I used filtered water, but I'm sure tap will do as well.) Squirt in some dish soap. I'm not one to measure, but I would guess I put in 2-3 teaspoons. Screw on the cover and gently shake to combine the soap and water. Voila!
Pump and scrub away! Just like a new store-bought bottle!
