Hopped is fine for wipe off and soft scrub if needed. It is NOT fine for soaking the parts that are nickel plated.

Why even take the chance with Hoppes?

The laws of chemistry and physics apply. It is not a chance unless contact lasts hours and hours. It is a great cleaner and if it is what you have you should not have an unfounded fear of using it. Just know what it is how it works and you are good to go.
