The durability of whisky glasses is directly related to their maintenance methods. Crystal glasses are prone to scratching, while regular glass ones are likely to crack. It is necessary to master targeted usage and maintenance skills to extend their service life and ensure a good drinking experience.

I. Preventing Crystal Glass Scratching: Protecting Delicate Texture

Crystal glasses have thin walls, high hardness, but high brittleness. Tiny scratches can damage their aroma-concentrating effect. The key to maintenance lies in "avoiding friction and gentle handling":​

· Prevent collisions during use: Hold the body of the glass instead of the rim to avoid finger friction on the rim edge; place the glass away from metal tableware and hard objects to prevent collisions caused by sliding on the table; control the pouring speed to avoid hidden scratches on the glass wall from the impact of liquor.

· Proper cleaning methods: Do not use a dishwasher; hand washing is required. Use a soft sponge or special glass cloth, dip it in neutral detergent, and wipe gently. Do not use steel wool or hard brushes; when rinsing, avoid direct contact between the glass rim and the faucet, and you can pad a soft cloth for cushioning.​​

· Avoid friction during storage: Wrap each glass in a soft cloth or place them in a cup rack with partitions to prevent squeezing from stacking; when not in use for a long time, you can pad tissue paper inside the cup to prevent moisture, and place it in a dry and ventilated place to avoid material aging and embrittlement caused by a humid environment.​

II. Preventing Regular Glass Cracking: Avoiding Temperature Differences and Impacts​

Regular glasses have poor heat resistance and are easy to crack due to sudden temperature changes. The core of maintenance is "controlling temperature differences and preventing impacts":​

· Control temperature differences during use: Do not let a glass that has just held boiling water come into contact with cold water or be put into the refrigerator immediately; for a glass taken out of the refrigerator, first pour a small amount of room-temperature water to preheat it before adding hot drinks; avoid directly using regular glasses to hold frozen drinks below -10℃, as low temperatures can easily make the glass structure brittle.​

· Prevent sudden changes during cleaning: Use warm water for cleaning, and do not rinse a cold glass directly with boiling hot water; if there are dried liquor stains inside the cup, first pour warm water and soak for 10 minutes before cleaning to avoid cracking the glass wall due to forced scraping.​​

· Anti-falling and load-bearing precautions: Avoid holding the cup with one hand and operating in the air to prevent accidental dropping; do not fill regular glasses with more than 80% of their capacity, especially for hot drinks, to reserve space for expansion; when using outdoors, choose styles with silicone protective sleeves to reduce collision impacts.​

III. Universal Maintenance Tips​

· Regular inspection: Check the glass wall before each use. If there are obvious scratches on crystal glasses or tiny cracks on regular glasses, replace them in time to avoid cracking during continued use.​

· Avoid misuse: Do not use whisky glasses to hold acidic drinks or carbonated drinks. The former may corrode the crystal surface, and the latter may easily cause a sudden increase in internal pressure due to bubbles.​

· Emergency handling: If a regular glass accidentally falls, clean up the fragments first. Do not pick them up directly with your hands; you can use tape to stick small debris to avoid scratches.​

In a word, the maintenance of crystal glasses focuses on "avoiding friction and gentle cleaning", while that of regular glasses focuses on "controlling temperature differences and preventing impacts". As long as you develop careful usage and cleaning habits, you can keep whisky glasses in good condition for a long time without affecting the flavour experience.
