Shampoo makes an excellent liquid hand soap, and it's loads cheaper than any soap refill that you can buy. Just fill your soap dispenser about a third of the way with shampoo; fill the rest of the space with water; and give the dispenser a good shake to combine everything.
Have a foaming soap dispenser? You can use shampoo to make your own foaming soap refill, too. Check it out:
Also Worth Trying: Add baking soda to a bottle of shampoo to create your own mechanic's/gardener's soap.
Cross shaving cream off of your shopping list for good. A squirt of shampoo works just as well, and will never leave those nasty rust stains on your tub.
Tip: Mix shampoo and conditioner together (or use a two-in-one) to give your skin and extra boost of moisture.
Save some cash and cut down on the number of bottles in your shower by using shampoo in place of your body wash. It will lather up beautifully and leave you smelling great.
Also Worth Trying:
Work a small amount of shampoo into any carpet or uplostery stain. Then, simply dab the spot with a damp rag until the stain lifts.
Tip: If you're worried about colorfastness, test this trick out on an inconspicuous area first.
Tip: Boost the effectiveness of the shampoo, by adding a bit of baking soda. It'll act like a scouring powder, and get that grease off even faster.
Shampoo is designed to cut through oil and hair product build up, so it works great on soap scum, too. Use it to clean your tub or shower, and you'll drastically reduce your scrub time. Just apply shampoo with a rag. Let it sit for a bit, and rinse clean. That's really all there is to it!
Have hair spray build up on your bathroom walls? Shampoo will remove that, too.
