Tumbler 3.75"D x 4"H, 12 oz., Glass Set: Mouth-blown glass, Rolled rim. Dishwasher safe. However, hand washing will prolong the life of the products. To maintain the original qualities, we advise some extra care. Before placing the glasses in the dishwasher, it is advisable to rinse them in lukewarm water to eliminate any residues. Once in the dishwasher, place glasses in the appropriate rack to avoid scratches. The washing temperature for the dishwasher should be 65 ºC (140 ºF) with a rinsing phase at 65 ºC (149 ºF) and a washing cycle of approximately 90/120 seconds. Carefully dose the brightener, an excess amount may cause iridescence on the glass surface, and a poor amount leaves water drop marks. At the end of the washing cycle, open the door and leave it ajar for 5-10 minutes to vent steam and avoid the formation of halos on the glass due to condensation. If washing glassware by hand, handwash glasses individually with a non-abrasive detergent, warm water, and a soft sponge or cloth.
