Dettol to the Rescue: Safely Removing Paint from Metal and Plastic Models
So, you’ve made a mistake. Or maybe your painting skills have improved tenfold since you last put brush to miniature. Perhaps you’ve stumbled upon an amazing paint scheme you simply *must* try. Whatever the reason, you’re faced with the daunting task of stripping paint from your metal and plastic models. Don’t despair! Before you reach for harsh chemicals, consider a gentler, more readily available solution: Dettol antiseptic liquid.
This guide provides a comprehensive walkthrough on how to effectively and safely remove paint from your models using Dettol, covering everything from preparation to clean-up, and addressing potential pitfalls along the way.
## Why Dettol? The Benefits of a Gentler Approach
While there are many commercial paint strippers available, Dettol offers several advantages:
* **Relatively Safe:** Compared to harsh chemicals like brake fluid or industrial-strength strippers, Dettol is considerably safer to handle. While you should still wear gloves and work in a well-ventilated area, the risk of burns or severe respiratory irritation is significantly reduced.
* **Readily Available:** Dettol is a common household antiseptic, easily found in most supermarkets and pharmacies. No need to order specialized products online or make a trip to a hobby store.
* **Cost-Effective:** Dettol is generally more affordable than specialized model paint strippers, especially when dealing with a large number of models or larger-scale projects.
* **Effective on Acrylics and Enamels:** Dettol is surprisingly effective at removing both acrylic and enamel paints, the two most common types used in model painting.
* **Won’t Melt Plastic (Usually!):** This is a BIG one. Many harsh chemicals can damage or even melt plastic models. Dettol is generally safe for plastic, but *always* test on a small, inconspicuous area first, especially with older or brittle plastics.
## Important Considerations Before You Start
Before diving into the stripping process, there are a few crucial points to consider:
* **Type of Plastic:** While Dettol is generally safe, different types of plastic react differently. Older plastics, particularly polystyrene used in some older model kits, can be more susceptible to damage. As mentioned, always test on a small, hidden area first. Look for discoloration, softening, or warping.
* **Resin Models:** Dettol is usually safe for resin models, but again, testing is paramount. Some resins can become brittle or slightly sticky after prolonged exposure. Short soaking times are recommended for resin.
* **Super Glue:** Dettol will *not* dissolve super glue (cyanoacrylate). If your model is assembled with super glue, the parts will remain glued together. If you need to disassemble the model, you’ll need a dedicated super glue debonder (or carefully try freezing the model, which can sometimes weaken the bond).
* **Etched Brass and Other Metals:** Dettol is generally safe for metals like white metal, brass, and pewter. However, prolonged exposure to any liquid can cause corrosion, so it’s best to keep soaking times relatively short and thoroughly dry the metal afterwards.
* **Safety First:** Even though Dettol is relatively mild, it’s still an antiseptic. Wear gloves to avoid skin irritation, and work in a well-ventilated area. Avoid getting it in your eyes. Keep out of reach of children and pets.
## Materials You’ll Need
* **Dettol Antiseptic Liquid (Original Brown Formula):** This is the key ingredient. While other variations of Dettol might work, the original brown formula is the most reliable and widely recommended.
* **Gloves:** Essential for protecting your skin. Nitrile or latex gloves are suitable.
* **Airtight Container:** A plastic container with a lid is ideal for soaking the models. Choose a size that’s large enough to fully submerge the models.
* **Old Toothbrush:** A soft-bristled toothbrush is perfect for scrubbing away the loosened paint.
* **Water:** For rinsing the models after soaking and scrubbing.
* **Dish Soap:** For cleaning the models after rinsing to remove any remaining Dettol residue.
* **Paper Towels or Clean Cloths:** For drying the models.
* **Small Container for Testing (Optional):** For testing the Dettol on a small part of the model before soaking the whole thing.
* **Eye Protection (Optional but Recommended):** Goggles or safety glasses to protect your eyes from splashes.
## Step-by-Step Guide to Stripping Paint with Dettol
Now, let’s get to the actual process of stripping paint. Follow these steps carefully for the best results:
**Step 1: Preparation and Testing (Crucial!)**
1. **Choose a Test Subject:** If you’re unsure about how Dettol will react with your model’s plastic or resin, select a small, inconspicuous part (like the underside of a base or an interior piece) for testing. Alternatively, use a spare piece of sprue from the kit.
2. **Prepare the Test Container:** Place the test piece in a small container (a small plastic cup or even a bottle cap will do).
3. **Submerge in Dettol:** Pour Dettol over the test piece, ensuring it’s completely submerged.
4. **Wait and Observe:** Leave the test piece to soak for at least an hour, or even longer (up to 24 hours) for a more thorough test. Check on it periodically to observe any changes in the plastic or resin. Look for discoloration, softening, warping, or stickiness.
5. **Rinse and Inspect:** After the soaking period, rinse the test piece thoroughly with water and dish soap. Dry it with a paper towel and inspect it carefully. If you notice any damage, Dettol might not be suitable for your model, and you should explore alternative paint stripping methods.
**Step 2: Soaking the Models**
1. **Prepare the Soaking Container:** Choose an airtight container that’s large enough to fully submerge all the models you want to strip. A plastic food container with a lid works well.
2. **Submerge the Models:** Carefully place the models in the container, ensuring they are not overcrowded. You want the Dettol to be able to circulate freely around each model.
3. **Pour in the Dettol:** Pour Dettol over the models until they are completely submerged. Make sure all surfaces of the models are covered.
4. **Seal the Container:** Close the lid of the container tightly to prevent evaporation and keep the Dettol contained.
**Step 3: The Waiting Game**
This is where patience comes in. The amount of time you need to soak the models depends on the type of paint, the number of layers, and how well the paint was initially adhered. Here are some general guidelines:
* **Lightly Painted Models (Single Layer of Acrylic):** 12-24 hours.
* **Heavily Painted Models (Multiple Layers of Acrylic or Enamel):** 24-48 hours.
* **Very Stubborn Paint (Thick Enamel, Primed Models):** 48-72 hours or longer. You may need to change the Dettol halfway through for best results.
Check on the models periodically to see if the paint is starting to lift. You’ll notice the paint bubbling, flaking, or peeling away from the surface.
**Step 4: Scrubbing Away the Paint**
1. **Remove the Models:** After the soaking period, carefully remove the models from the Dettol solution. Wear gloves, as the paint will be slimy and messy.
2. **Prepare Your Scrubbing Station:** Set up a workspace with a sink or a container filled with clean water. Have your old toothbrush ready.
3. **Scrub Thoroughly:** Using the toothbrush, gently scrub the models to remove the loosened paint. Pay attention to crevices, details, and hard-to-reach areas. The paint should come off fairly easily with a bit of scrubbing. Don’t apply excessive force, as you could damage delicate details on the model.
4. **Rinse Frequently:** Rinse the models frequently with clean water to remove the paint debris and prevent it from re-adhering to the surface.
5. **Repeat if Necessary:** If some paint remains after the initial scrubbing, repeat the soaking and scrubbing process. Stubborn areas might require a second or even third soak.
**Step 5: Cleaning and Drying**
1. **Wash with Dish Soap:** Once you’ve removed as much paint as possible, wash the models thoroughly with dish soap and water. This will remove any remaining Dettol residue and ensure a clean surface for painting.
2. **Rinse Thoroughly:** Rinse the models thoroughly with clean water to remove all traces of dish soap.
3. **Dry Completely:** Dry the models thoroughly with paper towels or clean cloths. Make sure to remove any water from crevices and hard-to-reach areas. You can also use a hair dryer on a low setting to speed up the drying process. Make sure they are completely dry before priming or painting.
**Step 6: Inspection and Touch-Ups**
1. **Inspect Carefully:** Once the models are dry, inspect them carefully for any remaining paint. If you find any small areas of paint that you missed, you can use a hobby knife or a small file to carefully remove them.
2. **Address Glue Residue:** If there’s glue residue, you can try gently scraping it off with a hobby knife or using a dedicated glue remover (taking care not to damage the plastic).
3. **Ready for Priming:** Your models should now be clean and ready for priming and painting.
## Troubleshooting Common Problems
* **Paint Not Coming Off:** If the paint is not coming off easily, the soaking time might not have been long enough. Try soaking the models for a longer period, or try changing the Dettol solution.
* **Plastic Becoming Sticky:** If the plastic becomes sticky or tacky, it’s likely reacting negatively to the Dettol. Immediately remove the model, wash it thoroughly with dish soap and water, and dry it completely. Consider using a different paint stripping method in the future.
* **Discoloration:** Some plastics might experience slight discoloration after soaking in Dettol. This is usually temporary and will fade over time. However, if the discoloration is severe, it might indicate damage to the plastic.
* **Dettol Smells Bad:** Dettol has a strong, distinctive smell. Make sure to work in a well-ventilated area to minimize the odor. You can also add a few drops of essential oil (like lavender or eucalyptus) to the Dettol solution to help mask the smell.
* **Fine Details Breaking:** If you’re working with delicate models, be extra careful when scrubbing. Use a soft-bristled toothbrush and avoid applying excessive force. If any fine details break off, you can glue them back on after the stripping process.
## Alternatives to Dettol
While Dettol is a great option, it’s not always the best choice for every situation. Here are some alternative paint stripping methods to consider:
* **Isopropyl Alcohol (IPA):** IPA is effective at removing acrylic paints and is generally safe for plastic. However, it can be more aggressive than Dettol and might damage some plastics. Test first!
* **Simple Green:** Simple Green is a biodegradable cleaner that can also be used to strip paint from models. It’s less aggressive than Dettol and is generally safe for plastic, but it might not be as effective on enamel paints.
* **Biostrip 20:** A popular choice amongst hobbyists, Biostrip 20 is a water-based paint stripper, it’s generally safe on plastic and metal and removes most model paints.
* **Commercial Paint Strippers:** Commercial paint strippers are the most effective option for removing stubborn paint, but they are also the most dangerous. Use them with extreme caution, following all safety instructions carefully. Make sure they are plastic safe. Read the label!
* **Ultrasonic Cleaner:** An ultrasonic cleaner can be used in conjunction with Dettol or other stripping solutions to speed up the paint removal process. The ultrasonic vibrations help to loosen the paint, making it easier to scrub off.
