Default How to clean tubes?

Today I got a bunch of tubes. Most of them E88CC Philips, Siemens and TELEFUNKEN. The man who gave them to me, he had them in unsealed boxes. Tubes are very dusty and dirty. How should I clean them? What detergent should I use?

Please help.

Use any standard glass cleaner, best if alcohol based.

Regards.

+1.
This can happen very easily. You could be mortified if they were valuable NOS tubes.

Brasso or Silvo on the pins, although just fitting them is probably enough.

Warm water with a tiny drop of detergent and a very soft (artists ?) brush, then rinse and pad dry.

I get a label removed when cleaning a tube with water afew years ago. So now Iam very careful to clean tubes.
First I clean the tube with a soft dry brush, after it if need, I clean the tube with a wet soft cloth.
Alcohol definitely can remove the factory labels/codes.
