Maintenance tips for hardware locks

For example: Door handles at home, shower heads for showers, kitchen faucets, hinges for wardrobes, luggage trolleys, zippers on ladies' bags, etc. may be hardware materials.

Locks are the most easily overlooked hardware accessories in daily life, but in daily life we have to deal with all kinds of locks, these locks play a vital role in security. Most people neglect management after the lock is installed, and basically do not perform any maintenance on the lock. I will summarize some tips on the maintenance of locks.

1. Some zinc alloy and copper locks will "spot" for a long time. Do not think that this is rust, but it belongs to oxidation. Just rub it with surface wax to "spot".

2. If the lock has been used for a long time, the key will not be inserted and removed smoothly. At this time, as long as you apply a little graphite powder or pencil powder, you can ensure that the key is inserted and removed smoothly.

3. Lubricant should always be kept in the rotating part of the lock body to keep it rotating smoothly. At the same time, it is recommended to use a half-year cycle to check whether the fastening screws are loose to ensure tightening.

4. The lock cannot be exposed to rain for a long time, otherwise the small spring inside the lock will rust and become inflexible. The falling rain water contains nitric acid and nitrate, which will also corrode the lock.

5. Turn the key to open the door lock. Do not pull the key to open the door without returning to the original position.
