GDI Carbon Buildup Fix

Hello all hope you are all having a great day.

I want to ask about GDI engines and the issues with carbon buildup on the valves. Is that inevitable if you don't have gdi and port injection or is there a remedy to clean up the carbon if you only have a gdi? 

I have read that changing oil regularly is suppose to help but want to know of other things to take into consideration?

Anything helps and I appreciate it.

it's inevitable and you have to clean the engine regularly (walnut shell blasting for example).
