Removing dirt from an old bottle with a small mouth may take multiple attempts with different methods in order to achieve the desired results. Although abrasive chemicals may work to remove debris, they are often costly and potentially damaging to the bottle. Consider using a few common kitchen items to achieve the desired result.
Things You'll Need
- Plastic wrap
- Rubber band
- Uncooked rice
- Liquid dish-washing detergent
- Undiluted white vinegar
Fill the bottle 1/4 full with uncooked rice. The uncooked rice will scrub the dirt from the hard-to-reach crevices of the bottle.
Pour undiluted white vinegar into the bottle to the halfway point. The acetic acid in the vinegar will help loosen and dissolve the dirt.
Add the liquid detergent until the solvents in the bottle reach 3/4 of the bottle's full height. The detergent will break up any oils binding the dirt to the surface of the glass.
Cap the bottle with two to three layers of plastic wrap. Mold the plastic wrap around the neck of the bottle and secure using rubber band. Make sure the seal is tight enough to prevent leakage.
Shake vigorously for several minutes. If the solution does not shake easily remove some of the liquid. Turn the bottle upside down to see how the mixture takes effect. Repeat if necessary. The solution can be left overnight to allow the vinegar and detergent time to dissolve the dirt.
