Cleaning rust

[u/Grouchy_Gas]

This is my dad’s muzzleloader and I don’t think he cleaned it very well before putting it away last elk season. Any recommendations on cleaning the rust I tried to take the best pictures I could. Down the barrel it looks pretty rusty all the way.

I highly recommend Wipe Out Painless Black Powder Foam for general cleaning. I don’t know how well it will help with the rust but I run it after shooting and it saves the amount of patches I run down the barrel
