Looking good, Samantha!
Nice work!
Barkeeper's Friend has oxalic acid in it, which does a GREAT job in removing tannin stains from the hull and paint. It comes in a 'soft scrub' form, a thick liquid that is effective in a 'wipe on, rinse off, ' effort for this. The cleansing is chemical. No scrubbing necessary.
For tasks that require elbow grease, BK comes in a gritty powder canister, like Ajax or Comet.
Vinegar soaking works great on metal too, but don't soak more than 24 hours. I've restored many a rusty tool this way...
