Hello and welcome!
You can find the proper procedure for cleaning the dial scale here:

Just remember, rub lightly, don't apply pressure.
The chassis is at ground potential. Reception can often be improved by using a ground. If left ungrounded, the set's AC bypass capacitors does impress an AC voltage on the chassis, which is not strong enough to shock you but you will notice a tiny spark if you connect a ground wire to the set's GND terminal when the set is plugged in.
