I started cleaning out carbon more often afte seeing corrosion under carbon buildup. Sure, if you never clean it, you will never see it either.
YMMV - I cleaned mine. It is your tool and your money.
I have never seen corrosion under carbon in 30 years of shooting an AR platform,and after inspecting thousands firearms. Corrosion and pitting are not caused by carbon,that is a myth, it is caused by improper storage,and lack of lube as shown by testing done by E.A.G.
I'm not saying cleaning is a bad thing, but cleaning to excess is. These stupid gadgets are wastes of money, spend yours as you see fit.
