Using mineral spirits on concrete is primarily done to help lift and remove grease and oil stains.
Mineral spirits are a common solvent that can be effective in breaking down oily substances, making them useful for tackling stubborn stains like grease and oil on concrete surfaces. The process typically involves applying the mineral spirits to the stain and then using an absorbent material to soak up the dissolved residue.
Based on expert advice for removing grease and oil stains from concrete, here's how you can use mineral spirits:
Steps for Stain Removal with Mineral Spirits
To effectively use mineral spirits for cleaning grease or oil stains on concrete, follow these steps:
-
Saturate the Stain: Carefully pour or apply mineral spirits directly onto the stained area. Ensure the entire affected spot is thoroughly wet or saturated with mineral spirits. This allows the solvent to penetrate the porous concrete and begin dissolving the oil or grease.
-
Apply Absorbent Material: Immediately cover the saturated area with a generous layer of an absorbent material. The goal is for this material to soak up the mineral spirits and the lifted stain particles as the solvent evaporates.
According to the referenced advice, suitable absorbent materials include:
- Dry portland cement
- Talc
- Cat litter (specifically, the clay-based, non-clumping kind is often recommended)
- Fuller's earth
- Cornmeal
- Cornstarch
-
Allow Absorption: Leave the absorbent material in place for several hours, or ideally overnight. This gives the mineral spirits time to work and allows the material to fully absorb the stain.
-
Sweep and Repeat (if necessary): Once the material appears to have absorbed the liquid (it may clump or change color), sweep it away. If the stain persists, you may need to repeat the process.
Choosing Your Absorbent
The choice of absorbent material can depend on availability and the size of the stain. Materials like cat litter or portland cement are good for larger areas, while talc or cornstarch might be easier to use on smaller spots.
| Material | Notes |
|---|---|
| Dry Portland Cement | Effective, readily available for concrete work |
| Talc | Fine powder, good for small stains |
| Cat Litter | Clay-based types are highly absorbent |
| Fuller's Earth | Very fine, highly absorbent clay |
| Cornmeal | Common pantry item |
| Cornstarch | Common pantry item, very fine |
Using mineral spirits combined with an absorbent material is a proven method for lifting challenging grease and oil stains from concrete, including relatively new surfaces like a driveway.
