Ok people, I had recently dug a cub scout neckercheif slide I would like to clean. A little soap and water got the bulk of dirt off but can’t get it all. Still trying to get more history on it (anyone know?) the most I’ve found is it’s from somewereetween 1982 (tiger cub scouts formation) up to 2015 ( tiger cub retired and just became tiger scouts with a design change)

My point though is it’s solid brass when new ones aren’t. I want to keep the aged patina look while cleaning it. My son is a Cub Scout and is like to preserve it for him 1 day to have.

Some of the dirt won’t come off with a toothpick, so I was thinking some kind of soak. I don’t wanna change the color though like I’ve heard olive oil will do.

Soap and water soak then soft brush.

That is about all that I found that works without changing patina or causing color changes.
Don't use oil.

Always test a method on something worthless.
