Here's a young volunteer taking the bike for a ride that was totally frozen with the chain like stone as shown in the above pictures. The chrome is getting cleaned, the chain is nice and loose again, it's lubed and riding just fine.
This old sting ray bike sat outdoors in a yard with leftover junk for four decades. A man had kept it out there from when his son rode it as a boy back in the 1960's.

It's taken here and the chrome is cleaned up, the chain and wheels are loosened up and made to ride again just like 40 years ago when it was new.

Note the chrome chain guard covered with rust.

Here's the chain guard with the rust removed after light brushing within a minute after applying USA Fluid. The chain is now loosened up and pedaling again.
