Can I use vinegar instead of an enzymatic cleaner on a polyester couch?

Vinegar can help neutralize odors, but it may not fully break down the urine proteins. For best results, use an enzymatic cleaner specifically designed for pet stains.

How long should I let baking soda sit on the stain?

Let baking soda sit for at least a few hours, or overnight, to absorb odors. Then vacuum thoroughly.

What if the urine stain has already dried?

For dried urine, rehydrate the area with water or an enzymatic cleaner, then follow the same blotting and treatment steps. You may need to repeat the process.

Part 1: Material and risk

When your dog has an accident on a polyester couch, acting fast is the key to preventing a permanent stain and lingering odor. Fresh urine is much easier to remove than dried, and with the right approach, you can keep your couch looking and smelling fresh.

Why Acting Fast Matters

Fresh urine is mostly water and urea, which makes it easier to blot up before it sets. Once it dries, the urine can bond with the fabric fibers and create a stubborn stain and odor. That's why your first move should be to soak up as much liquid as possible.
