If you have all of the lime and calcium off and you are left with a white haze you can try burnishing it with a thick mixture of Ivory soap and water. Use a cheese grater to shred the soap and mix it up with a little water to make a syrupy liquid. Then use the plastic pellets from from a beanie baby and some of the soap. Swirl it around, could take a long time. I prefer to use lead or copper shavings or pellets for added weight. Cuts down on time. I use a machine that spins a piece of PVC pipe which I put bottles in, etc. By looking at your stains, you will never, ever, in a million years, get them off with pineapple juice. I restore glass, and have tried everything from Polydent to acids.
