How To Strip A Tumbler With Citristrip

Stripping a tumbler, especially one with a durable powder coat or multiple layers of paint, can seem daunting. However, with the right tools and techniques, the process can be simplified. Citristrip, a popular and readily available paint and varnish stripper, offers a less harsh alternative to more aggressive chemical strippers, making it a suitable option for tumbler customization.
Materials and Preparation
Before beginning, gather all necessary materials. This includes:
- Citristrip Paint & Varnish Stripping Gel
- A well-ventilated workspace
- Gloves (chemical-resistant)
- Safety glasses
- A dedicated paint brush (disposable or easily cleaned)
- Plastic wrap (optional, but recommended)
- Scrapers (plastic are preferred to avoid scratching the tumbler)
- Paper towels or rags
- Mineral spirits or acetone (for cleaning)
- Baking soda and water (for neutralizing)
- A container large enough to submerge the tumbler (optional)
Preparation is key to a successful stripping process. Ensure your workspace is adequately ventilated, ideally outdoors or in a garage with open windows. Protect your work surface with a drop cloth or newspaper. Put on your gloves and safety glasses to protect your skin and eyes from the Citristrip.

Application of Citristrip
Apply a thick, even coat of Citristrip to the entire surface of the tumbler. Use the dedicated paint brush to ensure complete coverage, paying close attention to any edges, curves, or intricate details. The thicker the coating, the more effective the Citristrip will be in penetrating the existing finish.
Once the tumbler is fully coated, wrap it tightly in plastic wrap. This step is crucial because it helps to prevent the Citristrip from drying out too quickly. When Citristrip dries, its effectiveness diminishes. The plastic wrap creates a barrier that traps the solvents and allows them to work for a longer duration.
If you prefer not to wrap the tumbler, you can simply apply a very thick layer of Citristrip. However, be sure to check it periodically to ensure it remains wet.
Dwelling Time
Allow the Citristrip to dwell on the tumbler for the recommended time. The manufacturer's instructions on the Citristrip container will specify the appropriate dwell time, which typically ranges from 30 minutes to 24 hours. The exact dwell time will depend on the type of finish being removed and the number of layers present. For particularly stubborn finishes, leaving the Citristrip on overnight may be necessary.

Regularly check the progress of the stripping process. You can do this by carefully peeling back a small section of the plastic wrap and gently scraping the surface. If the finish is softening and lifting easily, the Citristrip has done its job. If not, reapply the plastic wrap and allow it to dwell for a longer period.
Removal of the Stripped Finish
Once the dwell time is complete and the finish has softened, carefully remove the plastic wrap. Use a plastic scraper to gently remove the softened finish from the tumbler. Work in small sections, applying consistent pressure to avoid scratching the underlying surface. For intricate areas or crevices, a small tool like a toothpick or a specialized detailing scraper may be helpful.
Dispose of the removed finish and used plastic wrap properly, following local regulations for hazardous waste disposal. Avoid pouring the stripped material down the drain, as it can clog pipes and harm the environment.
Cleaning and Neutralization
After removing the bulk of the stripped finish, clean the tumbler thoroughly with mineral spirits or acetone. This will remove any remaining Citristrip residue and prepare the surface for further treatment. Use paper towels or rags to wipe down the entire tumbler, ensuring that no traces of the stripper remain.

Neutralizing the surface is an important step. Create a solution of baking soda and water (approximately one tablespoon of baking soda per cup of water). Apply this solution to the tumbler and let it sit for a few minutes. This will neutralize any remaining Citristrip and prevent it from interfering with subsequent painting or coating processes. Rinse the tumbler thoroughly with clean water and allow it to dry completely.
Safety Note: Always wear gloves and safety glasses when handling mineral spirits or acetone, as these are flammable and can irritate the skin and eyes. Work in a well-ventilated area to avoid inhaling the fumes.
Dealing with Stubborn Areas
In some cases, certain areas of the tumbler may prove more resistant to stripping. This is particularly common around edges, seams, or areas with multiple layers of finish. If you encounter such areas, repeat the application process on those specific spots. Apply a fresh coat of Citristrip, re-wrap with plastic wrap, and allow it to dwell for a longer period.
Alternatively, you can use a more aggressive scrubbing tool, such as a scouring pad or a wire brush, to remove the stubborn finish. However, exercise caution when using these tools, as they can scratch the underlying surface if applied too forcefully. Test the tool on an inconspicuous area of the tumbler first to ensure it does not cause damage.

Final Inspection and Preparation for Refinishing
After cleaning and neutralizing the tumbler, carefully inspect the entire surface for any remaining imperfections or residue. Use a fine-grit sandpaper (e.g., 400-grit) to lightly sand the surface, smoothing out any minor imperfections and creating a better surface for adhesion of new paint or coating. Wipe the tumbler down with a tack cloth to remove any sanding dust.
The tumbler is now ready for refinishing. You can apply a new coat of paint, powder coat, or other decorative finish, according to your desired aesthetic. Follow the manufacturer's instructions for the chosen finish, and take the necessary precautions to ensure a professional-looking result.
Alternative Methods
While Citristrip is generally effective, other methods can be used depending on the tumbler material and desired outcome. For instance, sanding is a manual method that involves using progressively finer grits of sandpaper to remove the existing finish. This method requires patience and care but provides precise control over the amount of material removed.
Heat guns can also soften paint, making it easier to scrape off. However, using a heat gun requires caution, as excessive heat can damage the tumbler, particularly if it's made of plastic or thin metal. Always keep the heat gun moving and avoid concentrating the heat on one area for too long.

Considerations for Different Tumbler Materials
The material of the tumbler will influence the stripping process. Stainless steel tumblers are generally more durable and can withstand more aggressive stripping methods. Plastic tumblers, on the other hand, are more susceptible to damage from harsh chemicals or excessive heat. Always test the stripping method on an inconspicuous area of the tumbler before applying it to the entire surface.
Powder-coated tumblers often require longer dwell times with Citristrip, as the powder coat is typically more resistant to chemical stripping than traditional paint. Multiple applications may be necessary to completely remove the powder coat.
Safety Precautions Recap
Always prioritize safety when working with chemical strippers. Wear chemical-resistant gloves and safety glasses to protect your skin and eyes. Work in a well-ventilated area to avoid inhaling harmful fumes. Dispose of used materials properly, following local regulations for hazardous waste disposal. If you experience any irritation or discomfort, discontinue use and consult a medical professional.
Stripping a tumbler with Citristrip offers a method for customization and restoration. By following the steps outlined, individuals can effectively remove existing finishes and prepare their tumblers for new designs.
