Now it is time to deal with cleanliness. Pay attention to small areas where dirt appears and spots them. For minor defects, you can use vinegar and a microfiber fabric and wipe gently.
Alternatively, create your own natural upholstery cleaner, which you can use for this stage and next. Add a teaspoon of dishwashing liquid to a small bowl of warm water and use an electric hand mixer to whip it until the mixture makes soft peaks.
Slowly apply soap’s shud to stain with a soft-brisle brush and do not see some dirt until you take off. Use a spatula to remove most dirty foams, then rinse the rest with a white cloth and a very small amount of fresh water. Once the sound is completely removed, take a look at the stain whether you need to repeat the process.
