Stubborn shutter curtain on a Pentax 67 finally got me to switch methods

For years, I'd just use a cotton swab with a tiny bit of lighter fluid to clean old grease off the silk ribbons. It worked, but it was slow and I'd always worry about fraying. About six months ago, a repairer in Seattle mentioned using a synthetic chamois cloth dampened with pure isopropyl. I tried it on a sticky 67 last week, and the cloth lifted the gunk without leaving any fibers behind. It cut the cleaning time in half. Has anyone else found a better material for this specific job?

That synthetic chamois trick from Seattle saved my 67 too, but I still keep a bottle of lighter fluid handy.

Read about someone using a microfiber cloth with a drop of naphtha instead. They said it grabs the old grease without any risk of leaving bits in the mechanism. Makes sense, right? That chamois idea is clever for avoiding fibers, but I wonder if microfiber would be even easier to find. Still, if the isopropyl is working for you, why fix what isn't broken?
