What you’re going to do:
Put the rice, dishwashing soap, and vinegar in the glass, the bottle, or the vase and fill it up to the top with water. Put your hand on the opening of the glass or put the lid on the bottle and shake well. The rice scrubs away any filth from the glass. Repeat if necessary. Rinse the glass and let it dry.
Why does this work?
Rice is small enough to get into all the small nooks and crannies but big enough to not get stuck. It’s also good for scrubbing the glass clean without damaging the material. If the glass is in really bad condition let it sit overnight with vinegar inside before you test out the rice trick.
