During the process of using liquid silicone materials, one may inevitably encounter the challenge of cleaning uncured liquid silicone, where common household cleaners might not be effective. This article will introduce several more specialized cleaning solvents that perform excellently in removing liquid silicone.

Cleaning Solvents
1. Absolute Ethanol (Alcohol with Very Low Water Content): Absolute ethanol is ethanol with a purity of 100%. It is a colorless, transparent, flammable, and volatile liquid with low toxicity and a slightly irritating odor at room temperature and atmospheric pressure. Ethanol in a critical state has a strong dissolving capacity and can destroy the chemical structure of silicone.

2. Mineral Spirits: Mineral spirits are a type of solvent oil, typically represented by petroleum ether, mainly used as a solvent and for grease processing, but it is volatile and flammable. In laboratory column chromatography, petroleum ether (PE) and ethyl acetate (EA) are commonly used as eluents. It is important to note that petroleum ether should not be confused with gasoline.

3. Acetone: Acetone, a colorless and flammable liquid, exhibits a minty odor and possesses active chemical properties. It is capable of dissolving oils, fats, resins, rubber, and various substances. Additionally, it can dissolve cellulose acetate and nitrocellulose, making it an important volatile organic solvent.

Safety Warning
These chemical cleaning solvents are flammable and emit irritating odors, posing health risks to humans upon prolonged inhalation. When using these solvents, please take appropriate safety measures, including wearing personal protective equipment and ensuring good workplace ventilation. Additionally, considering these solvents might damage models or other items, a test should be conducted before use to verify their feasibility.
Simplified Handling Methods
Liquid silicone is a non-toxic material, and contact with the skin can simply be washed off with soap and water. If liquid silicone accidentally spills on the floor, it can first be wiped clean with a cloth; if the floor becomes slippery, sprinkling fine sand can effectively prevent slipping. This method offers an option for those seeking more environmentally friendly or minor cleaning solutions.
Through this article, we hope to provide a comprehensive and practical guide for individuals and professionals dealing with the cleaning challenges of liquid silicone, helping them choose the most appropriate cleaning method.
