What You'll Learn
Mineral spirits can soften and distort plastic
Mineral spirits, also known as white spirits, are a type of petroleum-derived solvent. They are highly effective in thinning oil-based paints and varnishes and are widely used for cleaning brushes, tools, and equipment. Mineral spirits are mostly hexanes and heptanes (C6/C7 aliphatic hydrocarbons), which are quite flammable.
Mineral spirits are generally safe to use on most surfaces and materials. However, they can soften and distort certain types of plastics. The susceptibility of plastic to distortion by mineral spirits depends on its composition. For instance, mineral spirits can damage polystyrene, especially Bandai plastic, which will crack or become brittle even with minimal exposure. ABS plastic, HDPE, and EPDM are also not suitable for use with mineral spirits.
On the other hand, mineral spirits are often supplied in plastic containers, indicating that some plastics are compatible. Polyethylene bottles, for example, are excellent choices for storing mineral spirits. Additionally, mineral spirits can be safely stored in HDPE containers, as evidenced by their use in storing and selling the product.
It is crucial to exercise caution when using mineral spirits with plastics. While some plastics are compatible, others can be melted or distorted. The safest option is to store mineral spirits in the container they were purchased in or to use an airtight stainless steel metal jar.
In summary, mineral spirits possess the ability to soften and distort certain types of plastics. The specific composition of the plastic plays a pivotal role in determining its susceptibility to degradation by mineral spirits. As a precautionary measure, it is generally recommended to avoid storing mineral spirits in plastic containers unless the plastic is known to be compatible.

Mineral spirits are sold in plastic containers
Mineral spirits, also known as white spirits, paint thinner, or mineral turpentine, are derived from petroleum distillate. They are commonly used for thinning oil-based paints and varnishes and for cleaning brushes, tools, and equipment. Due to their solvent properties, mineral spirits can indeed damage some types of plastic.
When purchasing mineral spirits, they are typically supplied in a plastic container, indicating that some plastics are compatible and can safely store the product. The original container that mineral spirits are sold in is often marked with "HDPE" inside a triangle, indicating that this type of plastic is suitable for storing mineral spirits. HDPE stands for high-density polyethylene, a type of plastic that is widely used and known for its strength and durability.
However, it is important to note that not all plastic containers are marked with their type of plastic, making it difficult to determine if they are safe for storing mineral spirits. In such cases, it is recommended to err on the side of caution and choose alternative containers made of glass or stainless steel. Glass jars, such as canning or Mason jars, are often recommended for storing mineral spirits and similar solvents. Stainless steel metal jars with airtight lids and clips are also a reliable option for safe storage.
While mineral spirits are sold in plastic containers, it is crucial to be cautious when reusing plastic containers for storing mineral spirits. The safest option is to use the original container that the mineral spirits were purchased in or choose alternative containers made of glass or stainless steel to prevent any potential damage or leakage.
