okay to use steel brush to polish pins?

Tubes Asylum

Questions about tubes and gear that glows. FAQ

I have some NOS tubes with corroded pins. I read that you can use a short brass brush to polish them. You can even attach a brass brush attachment to a dremel and spin it, but that would be a bad idea for me as I'm very clumsy and would most likely bend the pins.

So I ordered some short brass brushes from Amazon and gave it a go. There was essentially no corrosion removed after brushing one pin for 10 minutes.

The set includes a steel brush. I brushed a couple pins with that for 5 minutes and they got shiny! However I'm wondering if this can scratch the pin and actually degrade performance of the tube.

Anyone have a recommendation?
