Finding that your foam sofa cushions have been damaged by urine accidents can be disheartening. But don’t worry – with the right cleaning methods and products, you can fully restore foam cushions after pet or human urine. It just takes some patience and persistence.

Follow these comprehensive steps to thoroughly and effectively clean urine stains, residues and odors from foam sofa cushions:

Act Quickly to Blot Up any Wet Urine

At the first sign of fresh wet urine on your foam cushions, quickly use paper towels, rags, or an absorbent cloth to blot and absorb as much of the liquid as possible. Try to avoid excessive rubbing, which can further push urine deeper into the cushion foam before you have a chance to extract it. Swift action here prevents the urine from fully soaking into the cushion.

Make a Vinegar Cleaning Solution

In a spray bottle, mix together equal parts white distilled vinegar and water to create your cleaning solution. The acetic acid in vinegar helps neutralize and dissolve the ammonia compounds in urine that cause lingering odors. Vinegar also acts as a natural stain remover.

Lightly Mist the Vinegar Solution Over Affected Areas

Lightly mist the diluted vinegar cleaning solution evenly over the stained or smelly upholstery areas of the foam cushion. Avoid completely saturating the foam with liquid, which can take longer to fully dry out.

Make a Spreadable Baking Soda Paste

In a small bowl, stir and mix baking soda with just enough water to form a thick paste consistency that can be easily scrubbed into fabrics. Baking soda will help absorb and neutralize stubborn urine odors.

Use a Soft Brush to Work Paste into Cushion

Use a soft bristle upholstery brush, small towel, or your fingers to work the baking soda paste thoroughly into the stained or smelly areas of the foam cushion. Scrub gently but diligently to lift odors and stains.

Rinse Clean with Fresh Water

Once you’ve scrubbed the baking soda paste over all affected areas, use a clean damp cloth or towels to wipe away any vinegar solution or baking soda residue remaining on the cushion surface. Blot gently to lift out as much moisture as possible.

Rapidly Dry Cushions with Fans

Stand cushions on their sides or ends and use stationary or oscillating fans directed at the upholstery to accelerate drying time. Rotating cushions occasionally exposes all upholstery sides to maximize air circulation.

Deodorize with Odor Absorbing Powders

Once cushions are fully dried, sprinkle baking soda powder or other odor eliminating powders generously over the surface. Let powders sit for a minimum of a few hours up to overnight before thoroughly vacuuming away.

Repeat Cleaning Process as Needed

For severe urine stains or stubborn embedded odors, repeat the cleaning process 1-2 more times for best results. Patience and diligent repetition using these methods will allow you to fully restore urine-damaged foam cushions.

With the proper cleaning technique and common household products, even set-in urine stains and odors can be completely removed from foam sofa cushions, restoring them to fresh comfort again. Don’t give up too quickly!
