Cleaning antique glass bottles inside???

I have several antique glass bottles that have mineral deposits buildup inside them. How do I rid myself of this problem?

Put a tablespoon or so of vinegar, about a teaspoon of dry rice and a drop or two of liquid dishsoap. Then fill halfway with water. Give a good strong shake, let it sit for a few minutes, another shake, etc. They will sparkle after a few shakes and sitting. Then rinse and dry!

let undiluted white distilled vinegar sit in them for a few hours. Add a little rice or sand and shake vigorously to loosen stubborn stains. Repeat if necessary. If the rice don’t work get a baby bottle cleaning brush.

Don’t go crazy. Try vinegar first if the bottle is made of glass. Rinse all vinegar out before using the detergent then buy DAWN dish detergent. Pour a little detergent in bottle, use a bottle brush but cover the metal parts with a fabric tape. Don’t scratch the bottle neck or insides.
