Protect the Knob
When painting a home, there are areas you want to leave out like the doorknobs. There are many ways you can prevent your doorknob from getting stained with paints but using aluminum foil is easy and cheap. Not only will it protect the knob from paint, but it also prevents it from getting scratched when moving furniture.
Get a wide aluminum foil, wrap around the doorknob neatly and it’s done. This can also be done to prevent dirt when home improvement projects are ongoing. One of the best foil hacks!
