Grease stains ruin the appearance of wood decks.

Wood decks provide convenient spaces for entertaining, relaxing, cooking and other outdoor activities. Their natural appearance adds aesthetic appeal to home exteriors and landscapes. Food drippings from grills and barbeques can leave unsightly grease spots on deck surfaces. Grease spots become more difficult to remove the longer they soak into wood. Frequently clean wood decks to preserve their appearance and prevent them from absorbing stains. Promptly remove grease from a wood deck using basic solutions and supplies.


Step 1

Cover the vegetation around the perimeter of the deck with plastic drop cloths for protection against runoff.

Step 2

Fill a clean plastic bucket with 1 gallon of hot water and 2 tbsp. of liquid dish detergent. Thoroughly mix the solution.

Step 3

Dip a long-handled nylon brush in the soapy water. Scrub the deck with nylon brush to dissolve the grease.

Step 4

Attach a spray nozzle to a garden hose. Spray the deck with water from the garden hose to wash away the soapy water.


Step 5

Inspect the deck for remaining grease. If grease remains, squirt liquid dish soap liberally onto the spots and stains. Refill the plastic bucket with fresh hot water.

Step 6

Scrub the remaining grease stains with the nylon brush. Frequently dip the brush in the hot water to create lather.

Step 7

Rinse the deck with water from the garden hose to wash away the dirty solution. Allow the deck to air dry.


You can substitute liquid laundry soap for the liquid dish detergent.


Test the solution on an inconspicuous area of the deck to ensure the wood does not become discolored.
