Loosed Up Your Locks
If you have a lock that is a bit sticky or difficult to turn, graphite might be the solution. Oil in locks often clogs up the lock and can actually make things worse, but using a spare pencil tip to put some graphite in the lock is a great alternative. Graphite works as a great lubricant for these mechanisms without clogging them.
A Stripped Solution
During your DIY projects, there's probably been a time that you dealt with a stripped or stubborn screw. To loosen these difficult ones, place a rubber band on the surface of the screw. This will help your screwdriver or drill have more grip and will eventually loosen the screw from its place.
