How to Remove Black Mastic With Boiling Water and Vinegar

Written by chris simon | 13/05/2017

Vinegar is a natural cleaning compound for almost any cleaning task around the house. Toxic cleaning chemicals are bad for our health and the environment, and are not easily disposed of. A large bottle of distilled white vinegar is inexpensive, and will not damage household surfaces, including soft furnishings and carpets. Black mastic is one of the more difficult substances to remove from surfaces, but a solution including boiling water and vinegar can be applied to prevent permanent staining.

Scrape away the excess black mastic from the surface with a blunt knife, plastic spoon or plastic knife. Be careful not to scratch the surface you are cleaning, and discard the implement after use.

Mix 1/2 tsp baking soda, 2 tbsp white vinegar, 1/2 tsp liquid soap, and 2 cups boiling water.

Pour the cleaning compound into a clean, empty spray bottle.

Spray the mastic stain with the cleaning compound. Ensure the stain is fully covered.

Blot the stain with an absorbent cloth until it is completely removed. The stain may take some time to remove, especially from fabrics and carpets. Repeat the steps with more cleaning compound and absorbent cloths until the stain is removed.


Discard the used cloths containing mastic stains.


Do not use boiling water on woollen rugs or carpets.
