Remove rust on glass (beer bottle)

There I found during conversion work in the rubble two old beer bottles of the Stock Brewery Forest of 1912 and 1914, in which the temples were long ago "rusted away".

Since I wanted to leave these findings to the local museum, I tried using various methods to remove the vile rust spots on the glass. No chance. So I rinsed out the two bottles and handed them over to the local museum.

The head of the local museum was delighted with the find - and later told me how they had removed the rust from both bottles: with Denture cleaners!
