Best way to fix these?

Sounds like the same thing, or it's very, very similar. Probably a lot cheaper at Walmart. I think I paid close to $20 for a bottle similar in size to window cleaner the last time I bought it from Sherwin Williams

I used rust converter many years ago with great results, but haven't seen it or used it in many years. I need to pickup a can. Very handy to have around with tractors and equipment. I really like using it in cases where there are seams or places you can't get to or see.

$5.77 for the 8 oz. bottle at Wal Mart.

Just came across this as an alternative way to treat rust and thought I'd share.
