Mineral spirits are frequently used to clean paintbrushes and thin oil-based paint, but they are also useful for various household cleaning tasks, such as cleaning tile that has dried grout or clearing out any debris clogging your garden tools. Mineral spirits are a useful tool to have on hand—that is, until it’s time to discard it. Handling leftover or unused mineral spirits needs greater caution than handling other home waste due to potential safety hazards. This article will explain how to dispose of mineral spirits rags at home or after cleaning.

What Are Mineral Spirits?

Although this isn’t entirely correct, some people may believe that “mineral spirits” is merely another term for paint thinner. One type of solvent that is made from petroleum is called mineral spirits, and it is used to thin oil paint.

Any solvent that can be used to dilute paint is referred to as paint thinner. Product labels that read “paint thinner” frequently contain acetone, mineral spirits, and other chemicals, but not necessarily. One type of paint thinner specifically made for use with lacquer paints is called lacquer thinner. Instead of mineral spirits, it could be produced with denatured alcohol. Each product has a different formula for paint thinner. Nowadays, there are also natural paint thinners that are safe for the environment—like those made from citrus peel.

These differences are important when selecting the appropriate product for a task, but they become less significant when discarding them. The main handling guidelines for mineral spirits, conventional paint thinners, and other strong solvents are the same.

How to Get Rid of Mineral Spirits at a Hazardous Waste Facility

Mineral spirits have an extended shelf life when kept sealed. They could be lying around the house from a cleaning or degreasing project, or from painting. They essentially have an endless shelf life as long as the cap is securely fastened to the container. Years are at stake here. However, there are instances when getting rid of them is necessary. Mineral spirits must be taken to a facility that can properly dispose of them because they are a hazardous waste substance.

Locate the Nearest Facility

Every large county and city has a location for disposing of hazardous trash. It’s really simply a matter of finding one close as mineral waste disposal centers sometimes offer free mineral waste disposal.

Fortunately, the Environmental Protection Agency (EPA) maintains a database where you may locate a facility to get rid of mineral spirits. To complete the process, simply enter your location data.

Ensure the Safe Storage of Mineral Spirits Before Discarding Them.

Store mineral spirits carefully until you’re ready to discard them. As the original can or container is made specifically to prevent them from reacting with air or other chemicals, keep them in it.

Instead of keeping the mineral spirits in your home, keep them in your shed or garage until you’re ready to discard them. The storage area you employ should ideally be free of any heat sources.

How to Dispose of Mineral Spirits Rags

Remember that you must dispose of the rags or applicators you used appropriately in addition to the mineral spirits. Hazardous garbage also includes rags that contain mineral spirits on them. Contaminated rags can quickly catch fire and present a concern to the environment, much as mineral spirits.

  1. Make sure the rags are totally dry before discarding them. Several hours or maybe a day or two may pass, depending on the temperature and humidity.
  2. After the rags have dried, place them in a metal container that fits tightly on top. This could be a metal trash can or a paint can.
  3. Place the “flammable” container in an area with good ventilation, away from heat sources, sparks, and open flames.
  4. Either call a specialized business or dispose of the rags at a hazardous waste site.

Tips for Safe Mineral Spirit Disposal

The only safe place to dispose of mineral spirits is the hazardous waste facility. Tossing them away should never involve the following few things:

  • Never spill any chemical, even this one, on the ground. It can damage the ecosystem by seeping into groundwater.
  • Keep the container out of the garbage. Mineral spirits can contaminate groundwater once they are at a landfill, are flammable, and pose a risk to those who handle the trash.
  • Never empty them down the toilet or sink. Mineral spirits are not suitable for disposal since they can damage septic tanks and sewer infrastructure, as well as contaminate groundwater.
