Do NOT use emery paper or sandpaper on relay contacts. Even 1000 grit
emery paper can severely damage the contacts. If a true burnishing tool
that is made for such use is not available you can use plain old "bond"
paper cut into strips. In fact, usually you can use copy paper or
"computer" paper. When using paper strips immersing in some contact
cleaner like Deox-it or even WD-40 can help. Some people have had
excellent results using a dollar bill. However, it is pretty hard to get
a dollar bill into some areas that have a relay that requires cleaning.
Here is just one example of a burnishing tool. There are quite a few
others available from various manufacturers including one that has
replaceable blades.

Such a burnishing tool is excellent for cleaning contacts on telegraph
keys, keyer paddles, and so forth.

The 32S-3 relay contacts can normally be cleaned using a very fine grade
emery paper 1000 grit or better. Soak the emery paper in DEOX-IT first
then put slight pressure on the relay as you slide the emery paper between
the contacts.
