Contact Cleaning

[Anonymous]

For cleaning electical contacts, like battery terminals, rather than sand them try this.
Use a pencil eraser, or better yet an ink eraser
in place of the sand paper. I think you will be pleased with the results and it won't take off excessive matal.

I've used erasers as well and it "is" definitely better than sand paper, etc which remove too much metal in my opnion.
However, one caveat I've read about is that some erasers are apparently somewhat acidic and can cause corrsion. Not sure how bad this approach might be but for some time now I have favoured using the appropriate electronic contact cleaner. You should use it sparingly and carefully as it can interact with other parts of your detector, such as , some plastics, etc. I apply it with long handled Q-Tip type applicators rather than use the spray-on can types as you can control the application much easier.

Might be true but I have never had any problem with it. You would think the contact cleaner would be the right way to go but if you don't have that on hand you might have an eraser.
Also baking soda in water should nutralize some acidic corrosion. Next?

I agree that the eraser would be a great solution if you run into a problem out in the field. And I don't think the occasional use would cause much of a problem 8^).
I admit I have used the eraser many times in the past on numerous electronic components and haven't noticed much of a problem. Just thought I'd add the caution for those who are more finicky (sp?) than me 8^P.

Or better yet...use the Q tip to apply a thin coat of gel silicone after the erasure trick...Thin is key. And DO NOT USE
W-D 40 on this. In law enforcement we have found out with deadly results the vapors can have on nearby components ( can penetrate bullet casings and render primers useless ) can also corrode some plastics. Silicone Gel will prevent most all further corrosion unless you leave batteries in detector until the next century or give it a salt water bath! bill
