If squeaky wooden floorboards and creaky door hinges are preventing you from raiding your refrigerator after midnight in secret, you might already have everything you need in your kitchen to fix that problem.
Applying some sort of lubricating oil on the door hinge usually fixes the door squeak right away. You can use olive oil, butter, paraffin candles, WD-40 spray, petroleum jelly, or simply a bar of bath soap.
While this only applies to wooden floorboards that don't have carpet on top, you can also try fixing the squeak on your floor by dusting cornstarch in-between the floor boards to prevent the friction that causes the creak.
