Vintage lenses sometimes have cemented lens groups, using Canada Balsam - from trees. It goes bad, becomes hazy, rainbowy, and needs fixing.
Today we test if mineral oil can suffice as a replacement. Long term? Who knows! Right now? Yes. It somehow does.

Now, I'd advise this is best in lens groups where the housing holds the elements TIGHTLY together - the oil is not glue and any movement may scuff the image. The refractive index may be close enough here that IMO image quality is good enough.
