I was given a Bosch drill from a customer which needed replacement brushes to get going.

All done, but the shaft near the bearing (and part of the bearing cage) at the front of motor cage has suffered over the years it has been in storage, with some corrosion on the shaft which, if I don't deal with it might shower the new parts with rust particles that will get thrown off.

So, what do people use these days to clear up corrosion ?

I would normally use a small wire brush to get rid of the loose parts, then coat the remainder in light oil and grease, but this isn't really an option in this case.
For smaller items I have been known to use the full-fat coco cola and leave overnight, and this gets rid of dirt and other in most metals, but doesn't work particularly effectively with iron.

I do have a small ultrasonic tank, but I might be doing more damage with warm soapy water.

Is there a reducing agent in a pot out there that can deoxidise rust ?

Ah, should have mentioned the full set of options earlier

1) Wire brush (potentially a suede/brass one as opposed to steel)
2) Coca cola, or possibly vinegar
3) Electrolysis - plastic bucket , DC supply, water and electrodes
4) Ultrasonic tank

CH,

I have used electrolysis with washing soda as electrolyte and it worked OK. There is a topic on the forum that I created with some pictures of the items (Jaeger 1224 plates). What I found was that best results were achieved by leaving the parts in the tank for a day or two then rinsing them clean, followed by back in the tank for another day to finish the job off.

There's a lot of info and guidance in some car magazines - notably the Kit Car ones and "Practical Classics" (that make's a pretty good read anyway!)

I use Kurust, which is a deoxidising agent in a pot, available for around a fiver from Motor Vehicle Parts shops and eBay etc.

That stuff's been around for years in one form or another but the current formulation is "useless" as they had to remove the phosphoric acid, and there are a number of more modern, albeit more expensive, professional formulations that appear to be a lot more effective - will try to identify some of those this evening.

Therein lies the problem, each magazine article has a different 'best fix' which is why I'm asking here.

Option 5) is Mr Muscle oven cleaner, suggested by a works colleague. Even if it isn't the best it really does impart a lovely aroma in the house.
