Try Boeshield T9 Chain Lube. It's a kind of wax-oil for a lot of applications.
Clean chain with solvent to remove grease, dry, carefully thoroughly coat, immediately wipe off excess, let sit a day or more to harden up and spin a few times meanwhile. Lasts a long time and you can probably Triflow over it if ever needed. It's very difficult to remove any built up later on..which is a good sign.
