1. Blot the Stain:
- As soon as you notice the oil stain, blot it with a clean, absorbent cloth. Avoid rubbing the stain, as this will only spread it and make it more difficult to remove.
2. Baking Soda and Cornstarch:
- Create a paste by mixing equal parts baking soda and cornstarch.
- Apply the paste to the oil stain and let it sit for 30 minutes to several hours, or overnight.
- The baking soda and cornstarch will absorb the oil from the drywall.
3. Dish Soap and Water:
- Prepare a mixture of dish soap and warm water.
- Apply the soapy solution to the stain and scrub gently with a sponge.
- Rinse the area with clean water and blot dry.
4. Hydrogen Peroxide (for Light-Coloured Drywall Only):
- This method should only be used on light-coloured drywall, as it can potentially bleach darker colours.
- Apply a small amount of hydrogen peroxide directly to the stain.
- Let it sit for a few minutes, then blot with a clean cloth.
- Rinse the area with clean water and blot dry.
5. Dry the Area:
- Allow the affected area to dry completely. This may take several hours or overnight.
6. Spot Testing:
- Before applying any paint or other finishing materials, test the stain removal methods on a small and inconspicuous area of the drywall to ensure that they do not cause any damage.
7. Covering the Stain:
- If you're unable to completely remove the motor oil stain, you may need to cover it up with touch-up paint or a sealant.
- Ensure the area is clean and dry before applying any paint or sealant.
- Match the paint colour to the surrounding drywall as closely as possible, and apply it carefully to cover the stain.
- Allow the paint or sealant to dry according to the product instructions before moving any furniture or objects back into place.
8. Professional Help:
- If you are unsuccessful in removing or covering up the stain, consider seeking help from a professional cleaner or restoration service specializing in stain removal and drywall repair.
Remember to work carefully and test any solutions on a small area before using them on the entire stain.
