Properly maintaining your glass sink will prolong its life.
Step 1: Step One
Rinse both the outside and inside of the glass sink and wipe with a towel.
Step 2: Step Two
Use a glass cleaner or mixture of vinegar and water to coat the sink surface.
Step 3: Step Three
Dry well with a non-abrasive cloth. Avoid abrasive towels or scouring pads that may scratch the glass.
Step 4: Step Four
This step is optional. To shine the glass sink, wipe the surface with crumpled newspaper. This will leave a streak-free shine and is great for windows and mirrors, as well.
