Glassware should be cleaned immediately after use to avoid stubborn residues. Wash glassware in hot water and rinse with cold water. Crystal glass should be washed in lukewarm water. Scrub glassware thoroughly with a brush ensuring that all surfaces are covered. Do not use any harsh cleaning utensils such as steel wool pad to wash glassware as this will cause scratches.
For stubborn stains, use a mild detergent only. Always follow the manufacturer’s instructions and do not use more than the recommended quantities. After using a detergent, ensure that glassware is rinsed thoroughly to avoid any detergent residues being left on the glass.
Glassware can be washed in the dishwasher. However, take care not to wash glasses with very delicate long stems in the dishwasher as the possibility exists that these may break.
Avoid using scratched, cracked or chipped glasses
Avoid stacking glassware unless it is specifically identified as stackable. For best results store glasses in appropriate crates.
Do not expose glassware to an open element or electric plate and do not place it in the oven. Normal glass can withstand temperature changes of 42 degrees, and tempered glass can withstand temperature changes of 130 degrees.
Never allow glassware to be placed inside a microwave oven.
