If you enjoy the look of a glass vase in your home to show off floral arrangements, hold potpourri to give the room a pleasing fragrance, or hold pretty shells, pebbles, or sand to use as an eye-catching conversation piece, you will want to take the time to periodically clean out the interior. In time, the insides of glass vases can become encrusted in dust and residue from holding flowers in water. Here are some tips to use when cleaning the interior of a glass vase so it looks good as new. Cloudy Marks To remove a cloudy haze from the interior of a glass vase, use a mixture of vinegar and coarse sand. Pour a cup or two of vinegar into the bottle and add a few tablespoons of sand. Hold the vase and carefully shake it so the sand scrapes against the interior of the vase with the vinegar helping to cushion the abrasion. Do this for a minute and let the vinegar soak on the area for a half an hour before repeating the shaking process. This may take about a dozen shakes before the cloudiness disappears, but when it finally disappears you will be left with a vase that has a crystal clear shine. Staining To remove stains that have settled on the vase’s interior, fill halfway with water. Add an effervescent tablet used for indigestion. Leave the tablet in the water overnight. In the morning, the stains will miraculously be gone! Another way to remove staining is to fill the vase half-way with water and add a dish washing cleaning tablet. This will slowly disintegrate, spreading the cleanser in the liquid so it soaks the stain away within hours. For stains that are stubborn, you may need to follow the above methods with a vinegar soaking. Fill your sink with very hot water and add a cup of two of vinegar. Place the vase into the water, making sure the water completely covers the area with the stain. Allow to sit overnight. The next day, use a soft-bristled dish brush to scrub away any stains from the interior of the glass.  Floral Residue When you have residue left behind from using the vase for fresh flowers, you can make a paste to eat away at this material so your vase is clear once again. Place a tablespoon of salt in a small bowl. Add a tablespoon of vinegar and mix will. Use a long-handled toothbrush or dish scrubbing-brush to adhere the paste to the interior of the vase. Let the paste sit for a few minutes, scrub once again and rinse with water to remove the residue. Click here for more information on glass vase...
