After landing, as you taxi to your hangar or tie-down spot or fuel
station, try running the engine at about 1100 rpm while riding the
brakes to keep from going too fast. Do this for at least 1 minute, then
shut down. This heats up the cylinder heads and burns the lead off the
valves & plugs. Works for me.

You are right about having to lean and clean out the plugs. We had
to do this back in the 60's, but we were useing 100 0ctane leaded.
The Avgas now is 100LL (low lead).
To me, 100LL stands for 100 octane, Lotsa Lead (had wicked fouling
problems in our club's '69 C-172)
