How to Get Soap Scum Off an Aquarium

The milky layer on your aquarium walls may be soap scum left from a previous cleaning and inadequate rinsing, or it may be mineral deposits left from evaporated water. Regardless of what type of scum it is, the same natural substance -- possibly in your kitchen pantry -- will remove either one and leave your aquarium sparkling. Don't use glass cleaner or bleach.

Step 1

Pour 1/2 cup of white vinegar into a large mixing bowl. Add 1/2 gallon of distilled water. Pour the mixture into a spray bottle for easier use if you desire.

Step 2

Take a clean rag and dip it into the vinegar-and-water mixture. Wipe the rag over the soap or mineral scum to remove. For stubborn areas, use a new toothbrush to gently scrub and loosen the scum.

Step 3

Rinse the aquarium thoroughly with fresh water and set the tank out to air dry.
