Removing barbecue grease from concrete can be effectively achieved using heat-based methods that help liquefy and lift the stain. Two notable techniques involve using an old iron with butcher paper or applying boiling water.
Method 1: The Iron and Butcher Paper Technique
This method utilizes heat to draw the grease out of the porous concrete surface and into an absorbent material.
-
Materials You'll Need:
- An old iron (avoid using one you plan to use for clothing afterward to prevent grease transfer).
- Butcher paper (or thick, absorbent paper without ink that could transfer).
-
Step-by-Step Process:
- Prepare the Surface: Ensure the concrete area with the grease stain is clean and dry.
- Lay the Paper: Place a few layers of butcher paper directly over the grease spot. The multiple layers are crucial for absorbing the melted grease.
- Apply Heat: Heat your old iron to a medium-high setting. Gently press the hot iron onto the butcher paper covering the stain.
- Observe Absorption: As the iron heats the grease, it will liquefy and be drawn up into the paper. You should notice the stain transferring from the concrete onto the paper.
- Repeat as Necessary: Once a section of paper becomes saturated with grease, replace it with fresh layers and repeat the ironing process. Continue until the stain is significantly faded or no longer transfers to the paper. While its effectiveness can vary, this approach is worth a try for stubborn stains.
Method 2: Boiling Water for Grease Removal
Boiling water can melt the grease, allowing it to be removed from the surface before it has a chance to cool and re-solidify.
-
Materials You'll Need:
- Kettle or pot for boiling water.
- Stiff-bristled brush or broom.
- Absorbent rags or old towels.
-
Step-by-Step Process:
- Boil Water: Bring a sufficient quantity of water to a rolling boil.
- Apply in Small Doses: Carefully pour boiling water over the area in small doses. This helps to localize the melting action and prevents the grease from spreading.
- Immediate Removal: As the hot water melts the grease, it will rise to the surface. Promptly sweep the spot or dry the spot so any oil that melts will be removed. Use a stiff brush to agitate the area and push the liquefied grease away, or use absorbent rags to soak it up before it cools and re-sets into the concrete.
- Repeat and Refine: Continue applying small amounts of boiling water and removing the melted grease until the stain is visibly reduced or gone.
-
Safety Precaution: Always exercise extreme caution when handling boiling water to prevent burns. Consider wearing appropriate protective footwear and gloves.
For optimal results, it is generally recommended to address barbecue grease stains on concrete as quickly as possible, as fresh stains are easier to remove than those that have set over time.
