Removing polymer clay residue from glass can be tricky, but it’s manageable with the right materials and techniques. Here's how you can do it effectively:

Materials You'll Need:

• Rubbing alcohol (isopropyl alcohol)
• Acetone or nail polish remover (non-acetone removers can also work)
• Glass cleaner
• Microfiber cloth or cotton pads
• Plastic scraper or old credit card
• Baking soda (optional)
• Water

Step-by-Step Guide:

1. Initial Cleaning with Rubbing Alcohol

• Soak a microfiber cloth or cotton pad with rubbing alcohol and gently rub the glass where the polymer clay residue is.
• The alcohol helps break down the residue, making it easier to wipe away.
• For stubborn spots, let the alcohol sit for a minute or two before wiping.

2. Use Acetone for Stubborn Residue

• If rubbing alcohol doesn't fully remove the residue, try using acetone or nail polish remover.
• Soak a cotton pad with acetone and gently scrub the area. Acetone dissolves most of the oily or sticky residue left by polymer clay.
• Be careful not to overuse acetone on glass that has coatings or tinting, as it can damage them.

3. Scrape Away Hardened Residue

• For hardened or more stubborn bits of clay, use a plastic scraper (such as an old credit card) to gently scrape off the residue.
• Be gentle to avoid scratching the glass, and scrape at a shallow angle.

4. Baking Soda for Extra Cleaning (Optional)

• If there’s still residue left, mix baking soda and water to create a paste.
• Apply the paste to the glass and gently scrub the area using a microfiber cloth. Baking soda acts as a mild abrasive and helps lift away stubborn residue.

5. Final Wipe with Glass Cleaner

• After removing the residue, clean the glass with a glass cleaner to restore its shine and remove any leftover smudges from the alcohol or acetone.
• Wipe the surface dry with a clean microfiber cloth.

Additional Tips:

• Avoid using sharp objects (like razors) to scrape the glass, as they can scratch it.
• Test acetone in a small, inconspicuous area if you’re concerned about any coatings on the glass.
• Rubbing alcohol and acetone can evaporate quickly, so work in small sections for the best results.

Following these steps should help you safely and effectively remove polymer clay residue from glass!
