1. Freeze it. Blu-Tack will become brittle when it is frozen. To remove Blu-Tack from a carpet, place an ice pack or a bag of frozen peas on the Blu-Tack for a few minutes. Once the Blu-Tack is frozen, you should be able to scrape it off the carpet with a putty knife or your fingernail.
2. Heat it up. Blu-Tack will also melt when it is heated. To remove Blu-Tack from a carpet, you can use a hair dryer or a heat gun to heat up the Blu-Tack until it melts. Once the Blu-Tack is melted, you should be able to wipe it off the carpet with a damp cloth.
3. Use a solvent. There are a number of solvents that can be used to dissolve Blu-Tack. Some of the most common solvents that are used to remove Blu-Tack from carpets include rubbing alcohol, acetone, and WD-40. To use a solvent, apply a small amount of the solvent to the Blu-Tack and then rub it with a cloth until the Blu-Tack is dissolved.
4. Use a commercial Blu-Tack remover. There are a number of commercial Blu-Tack removers that are available on the market. These removers are typically made with a solvent that is designed to dissolve Blu-Tack. To use a commercial Blu-Tack remover, follow the instructions on the product label.
5. Get professional help. If you are unable to remove the Blu-Tack from the carpet yourself, you may need to get professional help. A professional carpet cleaner will have the experience and the tools to remove the Blu-Tack without damaging the carpet.
