Before you begin, gather the following supplies:

- Acetone or nail polish remover (ensure it contains acetone)

- Cotton balls or soft cloths

- Mild dish soap

- Warm water

- A soft brush (an old toothbrush works well)

- Paper towels

- A dull knife or spoon (to gently scrape)

- Patience and care

The sooner you address the glue, the easier it will be to remove. If the glue is still wet, take immediate action. Use a paper towel to blot the area, being careful not to rub it, which can spread the glue or push it deeper into the fibers.

Before applying any solvent, it's crucial to test for colorfastness. Choose a hidden area of the fabric and apply a small amount of acetone or nail polish remover. Wait a few minutes and check for any discoloration or damage. If the fabric holds up well, you can proceed.

1. Dab, Don’t Rub:

Use a cotton ball or soft cloth to dab a small amount of acetone directly onto the glue stain. Avoid saturating the fabric, as excessive moisture can damage it.

2. Let it Sit:

 Allow the acetone to penetrate the glue for a few minutes. This will help break down the adhesive bond.

3. Gently Scrape:

Once the glue has softened, use a dull knife or spoon to gently scrape away the glue. Be careful not to damage the fabric fibers.

4. Repeat as Necessary:

You may need to repeat the dabbing and scraping process several times, especially if the glue is thick or has dried hard.

After removing the glue, it's important to clean the area to eliminate any residue from the acetone:

1. Prepare a Soap Solution:

Mix a few drops of mild dish soap with warm water.

2. Dab with Soapy Water:

 Use a clean cloth to dab the soapy solution onto the affected area, wiping away any remaining glue and acetone.

3. Rinse:

Dampen another cloth with plain water and dab the area to rinse out the soap. Avoid soaking the fabric.

4. Blot Dry:

 Use a dry cloth or paper towels to blot the area until it’s as dry as possible. You can also place a fan nearby to help speed up the drying process.

Once the area is dry, use a soft brush to gently restore the fabric's texture. This will help lift any fibers that may have been flattened during the cleaning process, making the area blend in more with the rest of the sofa.

If the stain persists or if you’re unsure about handling the situation, it might be worth consulting a professional upholstery cleaner. They have specialized tools and techniques for dealing with tough stains without risking damage to your furniture.

To avoid similar accidents in the future, consider these tips:

- Use a Drop Cloth: 

If you frequently use nail glue or other adhesives, protect your sofa with a drop cloth.

- Be Cautious:

Always handle adhesives carefully, keeping them away from upholstery.

- Choose Alternative Products:

If possible, look for non-permanent adhesive options that are less likely to damage fabric.
