Thanks! I see patience is another ingredient I've seen to be missing when cleaning mineI played around with this batch.
-Started with several good soakings of Scrubbing Bubbles while they sat in a Tupperware container (allowing the excess to pool in the container).
-Scrubbed them thoroughly with a toothbrush
-Put them back in the container (with excess Scrubbing Bubbles still in), coated with a healthy amount of dish soap, filled it with hot water, and let them sit for about 4 hours.
-Scrubbed them thoroughly
Wasn't perfectly happy with the Flare-tip, so I tried putting it in a coffee cup, then pouring in boiling water, letting it sit until the water cooled, then scrubbing. Didn't really do anything.
-Finished up with a couple of cycles of spraying Kaboom and brushing the Superspeed and Flare-tip.
A helpful thing I've found is to use a toothpick to get at verdigris in hard-to-reach places, like behind the guard or in handle grooves.
I'm really enjoying the cleanup process! It's fun to get hold of things most people would think are junk and breathe new life into them.
