Hi Stefan,
No it isn’t necessary to unplug the battery before replacing the spark plugs, just be sure not to crank the engine over while the spark plug leads are removed from the spark plugs.

When changing spark plugs is it necessary to unplug the battery before commencing?

Hi Jason,
The best method for cleaning spark plugs is a gentle clean with a wire brush or wire wheel on a bench grinder. Using just enough pressure to remove any carbon deposits but not enough pressure to cause any damage to the porcelain around the centre electrode.
I would stay away from WD-40 and products like that as they may cause problems with the spark when the plug is refitted.
