Which lubricant to use...

Actually I want to speak of the lubricant not to use. I am talking about bearing or wheel grease. This is great stuff when used as intended, but very damaging when used incorrectly. On a car wherever grease is used it is capped off. This is to prevent any dirt or grime to contaminate the grease. When dirt or debris sticks to grease it then acts as sandpaper or grinder. It will destroy the item by wearing it down. I learned this the hard way a few years ago. I thought it would be a good idea to grease the wheels on my garage door, and for a while it seemed a great idea, until the wheels filed down to half their original size.

There are specific lubricants for all jobs, but I have found that WD40 works great on almost everything needing a little lube job. And an added benefit is that it also prevents rust by removing all moisture from a metal surface.

You know when you next take your car for a lube job, if you notice that the attendant is going to apply grease on the hood latch or door hinges, tell him "NO THANKS" not only will this do more harm than good, but just think of the day you are all dressed up and you find it necessary to look under your hood and just by touching the latch you get all full of black grease. Or for you ladies, think of the day you have a beautiful dress on and you are entering your car and part of your dress gets caught in the door jamb and lucky you it's all full of grease. As I always say, "It's better to prevent than to lament."
