To clean glassware, especially stubborn and hard-to-remove stains, follow these simple tips:
Use fresh lime to remove long-lasting stains on glass
Lime is great for removing stains on glass (soak lime for 10 minutes and rinse with warm water)
Cut a thin slice of lime and rub it vigorously on the stained area. Wait for 10 minutes for the acid in the lime to penetrate the stain. Then, rinse with warm water. Glassware that has been cleaned with lime will not only be shiny but also effectively eliminate any unpleasant odors.
Use vinegar combined with baking soda
Vinegar combined with baking soda can remove yellow stains on glass
Vinegar combined with baking soda will quickly clean the yellow stains on glassware. First, soak the glassware in white vinegar for about 15 minutes. Then, gently wipe the stains with a soft cloth soaked with baking soda. The stains will gradually loosen, and finally, rinse with clean water.
Use salt
Dissolve salt in a little warm water and pour it into a jar or glassware that needs to be cleaned. Soak it for a few minutes, then use a soft cloth to scrub by hand.
Toothpaste
Apply some toothpaste to the glassware and scrub the stains with a brush. The fluoride in toothpaste will leave the glassware clean and shiny.
Peel off adhesive tape on glassware
Use heat to remove labels on glassware
When you buy new glassware, the adhesive labels can be difficult to peel off. The easiest and most effective way is to use heat to loosen the adhesive of the label. Take the glassware out in the hot sun, and then use your fingers to peel off the label, which will be much easier.
Additionally, you can use 90o alcohol to soften the adhesive, then gently scrub with a sponge to remove it.
