Muting Model F Feet Springs?

[ChairmanMeow]

New member here. I recently restored and floss-modded my F122 (obligatory pics attached). However, the springs that control the keyboard's feet buzz quite a bit when typing with the feet fully retracted. Has anyone found a good way to prevent this? I'd greatly appreciate any suggestions. My springs are reasonably corroded, but I'm not sure if this alone causes the buzzing.

If you don't use them you could just take them out. Otherwise stuff them with foam rubber or some other insulating material to immobilize them.

Thanks for the reply. Unfortunately, I change the feet setting often depending on what desk I'm working at, so I can't remove them or immobilize them completely.

For anyone else with the same question and constraints:
Inspired by the grease mod, I smeared each spring in Vaseline and now the ringing/buzzing noise is gone. A reapplication of Vaseline in the future should remediate new buzzing that emerges with time. I also tried using new, corrosion-free springs that I cut up from longer ones, but they still created noise.
