Battery Corrosion
Around last Christmas I ordered a massive Tomy Thomas and Friends lot and got 4-5 trains from it and around 2-3 actually worked. When I took the battery covers off I noticed a ton of corrosion in the battery compartment and was wondering if anyone knew possibly how to fix or get rid of the corrosion
Hope everyone has a great day Heart

If you Google "how to remove battery corrosion" you'll get about 16,000,000 results. Most of the top ones appear to involve vinegar/lemon juice and bicarbonate of soda.  I prefer to use these in combination with a fine wire brush followed by a glassfibre eraser pen.

There's also a thread on here in the Modification Guide with a video on how to remove Battery Corrosion easily if that helps.
TooMuchThomas is never enough.

In addition to the suggestions above, the YouTuber 'Custom Trackmasters' has many videos of his repairing battery corrosion.

What is this " glassfibre eraser pen ", and what is it used for? I have not heard of this.

I originally came across these in the days before computer plotters when geological maps and charts were drawn by hand with a Rotring ink pen on Mylar (polyester) film. The glass fibre eraser pen was used for - erasing.  However they are still going strong, for example:

In my Drafting days we had battery operated erasers that did have different grades of replaceable eraser sticks that would work on paper or mylar but I haven't heard the term, Glass Fibre eraser before, in fact I can't seem to find out much about them here in the States. Could that just be a term you call them in the UK? If I remember correctly the replaceable eraser sticks back then were about 6" long.

Try "fiberglass scratch brush".

Thanks Dr Chris

Wasn't what I was expecting as I kept thinking of an eraser. I had seen the ones that have the steel and brass wire in them but had not known about the nylon and fiberglass ones.
