Combine the baking soda and dish soap in the gallon bucket before slowly pouring in both bottles of peroxide. The combination of ingredients will cause a reaction similar to a science project volcano eruption. While pouring, pause periodically to allow the level of foam to drop below the rim of the bucket before adding the remaining hydrogen peroxide.
Wash the skunk-sprayed area thoroughly with the solution using a sponge or nylon bristle brush. Wearing a breathing mask or respirator makes it easier to work on the spot without being as affected by the strong skunk odor. If any items where the skunk sprayed are removable, take them out of the house to be washed with the peroxide solution.
Remove and replace the air filters in the home's ventilation system. Open all of the windows in the house and turn on the whole house fan. Place a few outward-facing fans near the original spray area as well as near open windows to create an exit draft for the odors.
Mask any residual odors around the house by lighting scented or unscented candles and spreading out piles of freshly ground coffee beans.
Revisit the original skunk spray spot after two hours have passed. Rewash the area with the remaining solution if the skunk smell persists.
