A terrarium provides a unique view of nature, acting as a natural art piece full of vibrant plants and intriguing critters. However, the beauty is concealed when the terrarium glass is smudged or grimy. To keep terrarium glass looking beautiful, it must be cleaned, let in the necessary light and ensure clear visibility for watching your terrarium’s inhabitants. Below is an in-depth guide on how to successfully and safely cleaning your terrarium glass.

Preparation Materials

Before starting, gather the following items:

  • Distilled water
  • White vinegar
  • A spray bottle
  • Newspaper or paper towels
  • A small, soft brush
  • A rubber squeegee (optional)

Detailed Cleaning Steps

Empty the Terrarium

Carefully remove the plants, substrate and any animals or critters from your terrarium. It’s crucial to maintain a secure and stable environment for them while you undertake the cleaning. Keep them safe from temperature changes and potential predators.

Prepare Homemade Cleaning Solution

An effective, environmentally-friendly cleaning agent can be prepared with distilled water and white vinegar. In your clean spray bottle, use a ratio of one part white vinegar to four parts distilled water.

Give it a good shake to mix the contents thoroughly. Vinegar, with its slightly acidic nature, efficiently cuts through the layers of slimy grime and algae without harming your terrarium dwellers when they are reintroduced.

Application of Cleaning Solution

Apply the vinegar and water mixture generously to the interior glass surfaces of your terrarium using the spray bottle. Allow the solution to sit for some minutes—about 5 to 10—to ensure it penetrates and loosens accumulated grime to make subsequent scrubbing less strenuous.

Gentle Scrubbing

Using your small, soft brush, begin to scrub the interior surfaces of the glass gently. The emphasis here is on gentleness, as rigorous scrubbing may scratch or damage the glass. Begin from the top, working your way under to the bottom, to avoid dripping onto the already cleaned areas.

Rinsing and Drying

Once the glass is scrubbed, you’ll see dirty streaks where the grime has been loosened. Rinse the terrarium glass by spraying distilled water generously—again working from top to bottom—to carry the grime away. To dry the glass, use a lint-free cloth, paper towel, or newspaper.

For best results, a rubber squeegee can be employed for a streak-free and spotless finish.

Inspection and Final Touches
