How to remove rust on strut bolts?

[Releaseone]

I had the same issue. The conclusion I've made is that I'd better replace them with the new ones. But, anyway, I used vinegar to remove those bolts. It helped me remove the bolts. My friend from Scrooz recommended that I do it. Once, he helped me choose some screws and rivets at https://www.scrooz.com.au/fasteners/rivets/, so that's the reason I can trust him. Anyway, I really hope you've solved your issue. If you still have not done it, just try vinegar. It might work. Waiting for your reply. Best wishes, man.
