General maintenance recommendations and cleaning of glassware

First of all, check before each use and washing that the glass material does not show any damage (if you find that it is damaged, do not use it).
It is recommended to always wash this type of material before the first use, as well as immediately after each use.
If you suspect that the material may have come into contact with contaminated products, wash and sterilize it.

Cleaning recommendations to protect the printing on the glass:

• Never clean with abrasive products directly as they can damage the surface. Use a sponge or cloth impregnated with the cleaning solution.
• The glass material can be immersed in a bath at room temperature with the cleaning solution, rinsed with hot water and finally with distilled water.
• Avoid temperatures above 70°C, excessively long actuation times and strongly alkaline media (as this would affect screen printing and could lead to corrosion of the glass).
• Avoid mechanical aggressions during cleaning.

If a manual cleaning is performed:

1- Use a soft cloth or a non-scratching sponge with water and a mild cleanser. In general, do not use anything that can scratch the glass (spatula, etc.).
2- Do not use abrasive detergents that could damage the surface of the glass or erase the inscriptions.
3- Never allow the glass material to be soaked with strongly alkaline products.
4- Wash at room temperature and in case of immersion, do not soak the glass material for more than 30 minutes. Maximum water temperature: 70 °C.
5- Rinse with running water and then with distilled water.

If stem washing is performed:

Stem washing is less aggressive to glass than manual washing because the material is not in prolonged contact with the detergent.

1- Use a suitable detergent with the dishwasher and a mild detergent with the glass.
2- Place the material in the dishwasher in such a way as to avoid friction or breakage.
