Key to insert the door lock is very strenuous, how to solve?
You said is not the key is difficult to insert, you can add some pencil powder into the lock hole
Can not use mineral oil, because the mineral oil viscosity is highly polluted. It is not appropriate to use pencil or black graphite lubrication, can not be lubricated to the internal parts, and there will be heavy metal and color pollution.
Very simple, ah, the use of special lock lubricants drop a few drops on the cool cool rust, smooth.
Escala and other well-known lock factory mostly use tiger hotolube or Krupp kluber all synthetic lock lubricants. All synthetic base oil production, clear and transparent, colorless and tasteless, low temperature, not dust. Pot full of 30 ml tip small oil bottle, drop a few drops can be easy to use. The maintenance period is six months.
With a knife to the 2B pencil core scraped into fine powder, with a straw blowing into the door keyhole, insert a key to insert a circle, repeatedly eat, so that the pencil core powder choke the gap in the lock, ok. Do not pour any oil lubricant in the lock, then it seems to be effective at that time, but it is easy to stick the dust to make the lock more card.
