I am very new here.
Recently, I tried cleaning the inside wall of the barrel (only on the top part) of my Sailor 1911 demonstrator with a cotton bud dipped in ethyl alcohol 70% to remove some waterproof black ink stain. At first, the stain was removed quite easily. But as I left the barrel to dry, I noticed that the once clear barrel turned cloudy on the area that was affected by the alcohol solution. I have tried washing away the layer of cloudiness with water a few times, but it did not work.
I have not idea what exactly is the material of the barrel, could it be plastic or acrylic, that reacts to alcohol solution this way? So, is there anything I could do to restore the barrel to its original transparency again? Please advise, anyone?
