Sorry, but burnt phosphor is forever, and cumulative. All you'll 
accomplish is burning the rest of the tube, while burning the 
already-burnt spots even more. The only way to fix it is having the tube 
swapped for a fresh one. (Years ago, I heard of an outfit re-phosphoring 
monochrome tubes for a price that would - in those days - ALMOST buy you 
a new monitor, but color tubes were considered hopeless at any price)

Burn also varies by monitor make... Case in point:
I used to run a green-screen "Monitor ///" on my //e that spent several 
thousand hours (cumulative) of on-time as an ACOS/mACOS BBS system when 
I wasn't actually at the keyboard hacking on something. It never showed 
a sign of phosphor burn. On the other hand, a friend's amber Amdek 
monochrome, on a IIe running the same BBS software for a little under 4 
months, burned the idle screen into the tube so bad you could read it 
from across the room when the monitor was powered off - not just 
phosphor burn, but all-out phosphor *CHAR*.
