replace thermocouple on boiler

I notice that about every 3-4 years I need to replace the thermocouple on my boiler because the pilot light keeps going out. At the same time, I remove the 3 burners, tap and clean out all the rust and debris, and put them back as well.
I'm wondering if it's a good idea every year to turn the pilot light on the boiler from the ON position to the OFF position after the heating season, say around April or May, turn the thermostat from Heat to Off, clean the burners at this time and then again in the Fall, around October or when I think I may require heat, to relight the pilot on the boiler. Would I increase the life of the thermocouple and is this a good idea? Any other recommendations?

I turn off my gas pilot in the summer. Others prefer to leave it lighted.
