Some time ago, the lock of the security door at home was not good, so I put some vegetable oil in it

Oil can adhere to dust, and over time, the sludge enters the depths of the lock. The key does not fit into the groove with the lock cylinder after insertion. Naturally, it can't be opened. It can be cleaned with a cotton swab with gasoline. Just add some talcum powder.

Change the locks, it's a hundred...

I've encountered this before.,It's been a lot of hard work to pull it out.,After a few days, I can't pull it out.。。 It is said that some beads in the lock are stuck... It has nothing to do with lubrication.

Engine oil and vegetable oil are viscous oils, which are not suitable for lock cylinders, and it is best to use --- locomotive oil for lock cylinders.

Lock lubrication requires special, low-viscosity synthetic lubricants.

Most of the well-known lock factories such as Escola use fully synthetic lock lubricants from Hotolube or Kluber. Fully synthetic base oil production, clear and transparent, colorless and odorless, low temperature resistance, no dust. Tao is full of 30 ml needle-nosed small oil bottles, drop a few drops, easy to use.

The service interval is six months.

Mineral oil should not be used because it is highly viscous and tends to get dirty. It is also not suitable to use pencil end or black graphite lubrication, which cannot be lubricated to the internal parts, and there will be heavy metal and color pollution

Put vegetable oil, it is easy to stick to the ash, sticky, and it is best to put lead.
