Old school methods were to saturate internals of tankards etc. with melted beeswax to seal the wood pores.
I have several kitchen items and fruit bowls that can be subject to soft fruit acids and moisture splashes that are coated in melamine enhanced lacquer and are good to go some 10 years plus in use, they are never immersed but subject to a cold-water swill and dry on occasion.
Rustins Plastic Coating may well be a substitute.
Food Safe Oil (Liquid paraffin) soaked salad bowls and platters we have in regular use are wiped with a damp kitchen roll, never washed, detergents remove the oil dressing.
The addition of Microcrystalline wax may enhance the sealing after FS oil has had a few hours to settle.
I have used Melamine lacquer on the externals of goblets and FS oil on the internals for someone but have no idea on how long the finish lasted, probable as long as their fad lasted.
Large quantity of wine goblets done for a wedding had no dressing and lived with the wine stains, how long the guests hung on to or used them afterwards I’ve no idea.
