Most people have a bar of soap in their homes. In fact, there's probably one sitting in your bathroom vanity unit right now! But while you can certainly use a bar of soap to wash your hands or shave your legs, you might not realize that there are many other soap bar hacks out there. Whether you need help with a home repair or just want another environmentally friendly cleaning supply to add to your collection, a bar of soap is all you need. Don't believe us? Just check these out.

Fill Holes in the Wall

Whether you live in rented accommodation and want your deposit back or you've just bought a new home and the previous homeowners have left you some unsightly holes in the wall, you'll probably want to fill them. And while you could head to the Home Depot and buy some proper filler, why would you do that when this soap hack is a budget-friendly and environmentally-friendly alternative? It just makes sense to use a bar of soap.

This soap hack is super simple, too. All you have to do is rub the soap bar over the holes and let the soap find its way into the nooks and crannies. Then, you can paint over it.

Combat Smelly Shoes

Some people have smellier feet than others, and that's totally normal! But nobody wants smelly shoes in their house, which is why utilizing this soap bar hack may work in your favor. To combat smelly shoes, all you need to do is pop a bar of soap into each shoe. Ideally, you should wrap the bars of soap in a towel or napkin before doing so to ensure the soap residue doesn't soak into the fabric.

If you leave the bars there overnight, you should wake up to fresh-smelling shoes the next day. And when they start smelling again, just repeat the process and grab some more soap.

Stop Your Mirror From Fogging by Rubbing Soap on a Portion of It Pre-Shower

Everyone knows it's impossible to look at yourself in the mirror after a bath or shower, right? The mirror is normally fogged up to a point where you can't see anything, and wiping it rarely does anything to help. You don't have to live like that, though. By utilizing this soap bar hack, you can stop your mirror from fogging up as soon as you turn on the shower - and you'll be left with a fog-free mirror right until you turn it off again.

No, you don't need any fancy cleaning supplies. All you need to do is wipe the soap bar across the whole mirror and allow it to create a protective coating.

Freshen up the Smell of Your Clothes

You probably don't need us to tell you that clothes can smell a bit funky sometimes. It might be because you have no choice but to dry clean clothes indoors in a humid environment or because you shove them at the back of your old dresser. Whatever the case, you could wash them again to get rid of the smell - but that's not very budget-friendly. So, you could use a bar of soap instead.

All you need to do is wrap a bar of soap in a thin towel or napkin and then place it alongside your clothes in the drawer. If you choose one with your favorite scent, it'll work wonders.

Lubricate Old Screws

Although you can pick up buckets of brand-new screws from the hardware store, this is sometimes an expense that you weren't anticipating. And if you're looking to save money, working with what you have rather than buying new is a budget-friendly alternative that just makes sense. Thankfully, it's very easy to lubricate rusty old screws that just don't want to screw into your wall - and all you need is a bar of soap.

You'll need to add some water to the soap bar for this to really work, but when you start to see bubbles, you can rub the screw into the bar and instantly add some lubrication. Just make sure you don't let it dry out before using it.

Stop Dogs From Chewing on Things by Rubbing Soap on Them

Anyone who has ever had a puppy will know that these little guys love to chew and bite. And while this is all part of their development process, it's key to let your dogs divert this attention away from your furniture and onto something like a chew toy. But how do you do that? Well, the best way to stop dogs from ruining your furniture is to make your furniture less appealing to them.

You can do this by wiping a bar of soap over the legs and the fabric of the furniture. It shouldn't stain or mark it in any way, but it will taste horrible, so your dog will be less likely to take a bite out of it.

Grease Rusty Door Hinges

Is there anything more annoying than a rusty, squeaky, old door? No, we thought not! And while you may feel like you're out of your DIY depth when you notice one of your old doors start to squeak, we're here to tell you that it's actually much easier than you'd think to solve this problem. In fact, you should have everything you need to fix this problem if you have a bar of soap in the house.

If you grab your soap bar and wipe it directly on the hinges, you should grease them up enough to stop squeaking. However, you could also use liquid soap if you don't have a soap bar to hand.
