HP-IL newbie question

[Johnboy]

Thanks Dave,

I managed to clean the spring part by holding it up with an L shape piece of metal (a thin stainless steel headphone band from an old set of headphones) that could slip in under the spring. I put a hook in the other end so my finger can pull gently while I apply pressure to the spring to clean it. My tool for cleaning was a bamboo kebab stick that I sanded back to a wedge shape at the end. I dipped that in isopropanol, scrapped while holding the spring with my "L hook tool", then removed the greenish sludge using a cotton tip. I did that a few times, and now the brass rectangle on the spring is clean as !

Cheers,
John
