How to remove stains from silicone rubber products?

2025-04-02

As a manufacturer of silicone products, we have come to recognize that silicone rubber, as an environmentally friendly alternative to plastic, has been extensively utilized in daily life owing to its diverse characteristics. Based on the customer requirements we have analyzed and the customized products we have developed, they can be categorized as follows:


  1. Kitchen Supplies: Silicone baking tray mats, Silicone cake molds, ice trays, silicone spatulas, ladles, heat-resistant gloves, reusable silicone food covers, etc.   

  2. Baby Care Items: Silicone nipples, baby bottle protectors, teething toys, bibs, bath toys, etc.

  3. Electronic Accessories: Phone cases, tablet protectors, earphone cases, keyboard protective films, data cable interface protectors, etc.

  4. Household Items: Bathroom non-slip mats, coasters, furniture foot covers, silicone sealing rings, etc.

  5. Sports and Outdoor Gear: Fitness bands, water bottle covers, shoe insoles, etc.   

Additionally, in the industrial sector, silicone components are also widely utilized.

Although silicone products are mostly characterized by their scratch-resistant and anti-fouling properties, they still need to be cleaned after each use to maintain cleanliness and disinfection. This is also a good way to extend their service life.

Causes and Classification of Silicone Stains

  1. Surface Stains: Dust, fingerprints, food residues and other daily attachments

  2. Oily Stains: Cooking oil, cosmetics residues and other insoluble oils

  3. Chemical Adhesives: Glue residues, sticker residues and other stubborn adhesive substances

  4. Oxidation and Yellowing: Material aging caused by long-term exposure to ultraviolet rays or high temperatures

Four-step Basic Cleaning Method

1. Warm Water Pre-treatment

Soak the silicone products in 40-50℃ warm water for 10 minutes to soften the stains. Please note that boiling water should not be used as it may deform your product.

2. Neutral Detergent Cleaning

Choose unscented dishwashing liquid and gently wipe the surface with a soft sponge. Use a soft-bristled toothbrush to assist cleaning in the concave and convex textured areas.

3. Deep Rinse

Rinse repeatedly with flowing clean water to ensure no detergent residue.

4. Dry

Use an ultra-fine fiber cloth to absorb the moisture and place it in a cool and ventilated place.

Do not expose it to direct sunlight or dry it, as this will accelerate the aging of the product.


The method for removing stubborn stains


  1. Dishwashing liquid + warm water: Dilute at a ratio of 1:10 and soak for 20 minutes. Focus on brushing with a toothbrush (the dishwashing liquid can also be replaced with edible baking soda). This can remove oil stains and residual cosmetics.

  2. Alcohol wiping: Wipe the surface with 75% medical alcohol to dissolve adhered sticky substances.

  3. Lemon juice soaking: Mix fresh-squeezed lemon juice with water in a 1:3 ratio and soak for 30 minutes. This can restore the original color of the product.


Five Key Precautions

  1. Disabling Tools: Steel wool and hard-bristled brushes may scratch the surface.

  2. Chemical Prohibited Areas: Chlorine-based bleaches and strong acid and alkali solutions may damage the molecular structure.

  3. Temperature Limitations: The temperature range of resistance is usually -40℃ to 220℃. Extreme temperatures should be avoided.

  4. Protection of Electronic Components: Products with circuits are prohibited from being soaked.

  5. Special Treatment for Medical Grade: Implantable devices require dedicated disinfection protocols.
