Tried cleaning a Pentax K1000's prism with a drop of lighter fluid and it went cloudy.

I was in a rush and used a tiny bit on a cotton swab, but it left a permanent haze on the silvering. What's your go-to safe cleaner for old prism mirrors?

Lighter fluid on a prism is wild. That stuff eats coatings for breakfast. I just use a rocket blower and a soft brush for dust.

Remember the fumes can mess up the glue holding it together too.
