Glass items that you have picked up along a shoreline, such as "beach glass", may be covered in stains caused by the salt water. Depending on how long the glass piece has been sitting in the water, the stains may not be removable using a dish detergent or similar soap. A liquid that is commonly found in homes can be used to break up deposits found on glass items, removing the stains that are caused by salt water.
Things You'll Need
Undiluted white distilled vinegar
Bucket or sink
Sprayer or faucet
Fill a sink or bucket with enough undiluted white distilled vinegar so that the glass item will completely be submerged in the vinegar.
Soak the glass item in the white vinegar for one hour.
Remove the glass item from the white vinegar.
Rinse the glass item with hot water from your sink's sprayer. If the glass item is especially fragile, you can rinse the item with hot water from a faucet instead of a sprayer.
Dry the glass piece with a lint-free cloth.
Examine the glass item and repeat the cleaning process if you still notice salt water stains on the glass item.
