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.
