For stains that have become set-in, you can try these steps:

1. First vacuum the fabric to remove any dust or loose particles.

2. Then check your furniture for cleaning codes. This will help you to know whether or not you can use water on the fabric. If there are no cleaning codes to be found you can test water, vodka and vinegar on a hidden piece of upholstery to see if any of them stain.

3. If you can use water, begin with hitting the stain with a bit of steam to help loosen it up for treatment.

4. If water can be used then mix dish soap with a bit of cool water and with a wrung-out sponge, blot the stain with the soapy mixture. Do not rub as it isn’t good for the fabric. If water cannot be used, try using vinegar or vodka on a cloth to blot the stains, the smell will not remain after the fabric dries.

5. Next, (only if you are using water) rinse the sponge and use only water to blot out the soap.

6. Then press the fabric dry with a cloth or paper towel.

7. If the gentle clean did not work, it is time to break out a more heavy-duty cleaner that is meant for upholstery. Always spot test these in a hidden area.

8. After the chemical clean, if the stain remains, try repeating the entire process. Sometimes, more stubborn stains may require a couple of passes.
