Cleaning a transformer

[rtarbell]

Hello all,

I have an old EI core transformer encapsulated. The case itself is fairly dirty - rust flakes, and general grime. What is a good way to clean it?

Cloth dipped in cleaner of some kind. IPA is good, soapy water may do.

In the past I've used a wire brush to good effect.
Not sure the water is advisable...

WD40 is great for cleaning surfaces with old grime, on some transformers the case is only held with some bendoverclips at the bottom... I take em off and give them a quick coat of matt black from a can before reassembly...
