3. Apply solution correctly
Apply the prepared cleaning solution directly onto all silicone areas showing mildew. Use a spray bottle for even coverage or carefully pour the solution onto the affected joints. Ensure the entire stained surface is saturated so the solution can penetrate the mildew buildup effectively.
After application, allow the solution to sit for at least 30 minutes without disturbance. This dwell time is crucial for the vinegar’s acidity to weaken mold spores and for the baking soda to start breaking down the stains. Avoid rinsing or scrubbing immediately; patience improves the cleaning efficacy.
4. Scrub mildew stains
Once the solution has had time to work, use a small, soft-bristled brush—such as an old toothbrush—to gently scrub the silicone. Focus on the darkest, most affected areas, moving in circular motions to lift the mildew without damaging the sealant. Avoid harsh scrubbing tools that can tear or wear down the silicone.
For tougher stains, repeat the application and scrubbing process as needed. Persistent mildew may require multiple treatments before it fully fades. Always rinse the brush frequently to avoid redistributing spores.
5. Rinse and dry thoroughly
After scrubbing, rinse the silicone thoroughly with warm water to remove all residues of the cleaning solution and loosened mildew. Leaving solution behind can lead to discoloration or damage over time.
Dry the area completely using a clean, absorbent cloth or towel. Moisture left on silicone joints promotes mildew regrowth, so ensure no dampness remains. For best results, consider using a hairdryer on a low heat setting to speed drying in hard-to-reach corners.
