Ordinarily, one just disconnects the fluorescent fixture and can use sandpaper or a small file to polish the surface if it is burnt or corroded. It is very important that the lights be off, since the lights operate at thousands of volts and one could get a nasty shock. One other problem is the clips get bent.

The clips can be bent back into alignment with a pair of needle nosed pliers, but again, make absolutely sure the power is turned off.
