Prepare a solution - a tablespoon of baking soda per liter of warm water, stir well.
This solution should be used to wash the vase.
If the coating is strong, you can moisten the contaminated areas and let the product stand for several minutes.
You need to dilute a thick soda solution and tear the marked paper or newspaper into small pieces.
Place everything in a crystal decanter or narrow crystal vase, leave for a couple of hours, shake well, pour out and rinse with water.
Use a sponge or soft brush and warm water with mild dishwashing liquid diluted in it.
How you clean the interior depends on how dirty the carafe is.
The easiest way is to fill it halfway with warm soapy water and shake it with your palm over the neck.
Plain rice is an excellent cleaning agent for narrow-necked glassware.
Fill one third of the bottle with hot water, add a handful of rice and a couple of teaspoons of baking soda.
Seal the bottle tightly with the lid or hand and shake it vigorously for a minute or two.
