Protect a chrome salt shaker
TL;DR: is there something I can coat the inside of metal salt shakers with to protect them? Or am I missing a better clue?
I have two pairs of antique glass salt shakers (of significant sentimental value) with domed chromed tops, which are deeply corroded on the inside.
I've been unable to find modern shakers with matching tops to swap in (I've found a lot of shakers with chromed plastic tops, but not the right size and shape), so I'm slowly cleaning off the corrosion with vinegar, ketchup, and gentle elbow grease. (It appears that the inside was either unchromed base metal or the chrome has corroded away in places, but I'm not done cleaning yet.) (I know that other products such as ammonia and limescale remover are also recommended, but I'm sticking to gentler methods if I can.)
Assuming that the metal is structurally sound, is there a way to protect the tops so that they are less prone to corrosion? Is this something a silversmith could do for me? (I assume that invoking a professional would cost more than buying replacements.)

In my experience, you get out the nice shakers for a special occasion, then empty and rinse them when the event is over. Shakers that will corrode with salt can't really have the salt left in them long term

Beeswax is widely available, safe for accidental consumption, and will protect surfaces from the corrosive effects of atmospheric moisture and salt. Although bees are not harmed in the production, many vegans avoid it. People with allergies to pollen should avoid it.
Carnauba wax is a vegetable wax made from palm trees. It is hypoallergenic, and responsible for the shiny coating of a number of candies and similar edible products.
For either wax, rub it into the clean metal with a lint-free cloth until the surface is completely covered and slick. Use a small pick to reopen the pouring holes from the bottom up. Expect warm weather to cause salt granules to stick to the wax and occlude the holes.
