Tumbling of "Sick Bottles" and Decanteurs is something that can not be done on-site like most of the repairs we do. The bottles need to be placed in a machine with an abrasive powder and "tumbled" or turned so the abrasive scours the inside of the bottle. It typically takes one week of tumbling per step. Some bottles, depending on how bad they are, must run in the machine for up to a month. One of the most common questions asked is "Why do bottles get sick?"
I've done some research on my own and I've come up with two conclusions:
Hard water calcium buildups. Hard water contains Calcium. If you place this hard water in a bottle and allow it to evaporate, the Calcium is left behind. Usually this type of buildup can be removed with a simple household cleaner such as "CLR"
Another reason bottles get "Sick" inside is that they have been etched by chemicals in your drinking water. Sodium Fluoride is the most commonly used chemical to etch glass. This is what Wikipedia has to say about it:
Etching refers to the technique of creating art on the surface of glass by applying acidic, caustic, or abrasive substances. Traditionally this was done after the glass was blown or cast.
In the 1920s a new mould-etch process was invented, in which art was etched directly into the mould, so that each cast piece emerged from the mould with the image already on the surface of the glass. This reduced manufacturing costs and, combined with a wider use of colored glass, led to cheap glassware in the 1930s, which later became known as Depression glass. As the types of acids used in this process are extremely hazardous, abrasive methods have gained popularity.
Typically, "glass etching cream" available from art supply stores consists of fluoride compounds, such as sodium fluoride and hydrogen fluoride. The fluoridation of the glass (which is a network covalent solid of silicon dioxide molecules) causes the characteristic rough, opaque qualities of frosted glass.
Now.... The thinking person after reading the above should seriously think about doing some research on their own about Fluoride... After all, if it can do this to glass, what does it do to your body? Click here to see what most people are saying about Fluoride. Any further questions relating to this can be sent to me here.
