I'm working on restoring an old clarinet. The keys are badly tarnished - I've been working on them using a cloth and metal polish, but:
- It's very time consuming;
- I'm finding it impossible to get into all the corners, between the keys and the columns.
Does anyone have any experience with soaking keys, to remove tarnish chemically? I've heard of using a vinegar solution (a test is currently soaking now), and also this method using baking soda and aluminium foil. I'm also trying diet coke, as that's meant to be pretty corrosive.
Does anyone have any better ideas? I'm open to purpose-designed products, but wasn't able to find anything I trusted. Needless to say, a buffing machine, as the professionals appear to use is out of my budget.
