My stainless steel door key is very bad, dark whistle is always off, there is the keyhole is difficult to turn, close the door is very convenient door, please know how to deal with, change easily, easy to switch?
Should use colorless and transparent, good water resistance, low temperature resistance of the whole synthetic grease. Tao full 130 grams of toothpaste tube packaging, the effect is good.
Avoid using ordinary butter, low temperature will freeze, durability and water resistance can not meet the requirements.
Very simple, ah, the use of special lock lubricants drop a few drops on the refreshing 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.
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.
Hello!
Dark whistle off, because the inside of the oil dry, need to join the oil solution
The key is difficult to turn, just add a small amount of lead toner in the keyhole a few times to be able to solve a few times
