Choose a Safer Paint Stripper When House Painting

When repainting your property, there are times when it is necessary to remove old paint. And if you do, mere scraping usually doesn’t work, so you will need a paint stripper. 

However, traditional paint strippers often contain harmful chemicals like methylene chloride, which can be dangerous to your health and the environment. Exposure to methylene chloride can lead to dizziness, headaches, and even more severe health issues like respiratory problems and cancer. Also, the environmental impact of these chemicals is considerable, as they contribute to air and water pollution. They must be used only when proper ventilation is used.  

That’s why it’s important to understand the dangers associated with these traditional paint strippers and seek safer alternatives.

Eco-Friendly Alternative Paint Strippers

Thankfully, things have changed in the past years. Due to the growing interest in “green” buildings, more safe paint strippers are available in the market. Let’s explore three popular types: soy-based, milk-based, and citrus-based paint strippers.

Soy-Based Paint Strippers

Soy-based paint strippers are derived from natural soybeans. They are biodegradable and emit fewer toxic fumes compared to traditional strippers.

This paint stripper uses methyl coyote, a solvent from soybean oil. While this is a key ingredient, many popular brands also contain N-Methyl Pyrrolidone (NMP), which California warns can cause birth defects or the safer Bis (2 methoxy ethoxy) methane. These strippers are effective on paint and clear coatings, though they take longer to work and might need multiple coats. They’re easy to use, don’t drip, and are suitable for furniture, moldings, and cabinetry.

Benefits:

  • Environmentally friendly and biodegradable.
  • Low odor and safer for indoor use.
  • Effective on multiple layers of paint.

Limitations:

  • It can be slower to work compared to traditional strippers.
  • It may require more manual effort to remove stubborn paint.

Popular Brands: Soy Gel, SoyClean.

Milk-Based Paint Strippers

Milk-based paint strippers use casein, a protein found in milk, as the main ingredient. These strippers are gentle and safe to use.

These paint strippers come in powder form and are praised for their effectiveness and ease of use. They emit no toxic fumes and are simple to apply: just mix according to instructions, apply with a nylon brush, and rinse off with water after about an hour. These strippers are a safe and natural option for removing paint.

Benefits:

  • Non-toxic and safe for use around children and pets.
  • Mild odor and minimal environmental impact.

Limitations:

  • Typically, they are less powerful, so they may not be effective on very tough or thick layers of paint.
  • Best suited for small projects or delicate surfaces.

Tips for using milk-based paint strippers:

  • Apply a thick layer and let it sit for several hours or overnight.
  • Use a plastic scraper to remove the softened paint.
  • Rinse the surface with water to remove any residue.

Citrus-Based Paint Strippers

Citrus-based paint strippers use d-limonene, a natural solvent found in citrus fruits. It contains citrus peel extract, but like soy-based strippers, it also includes other solvents, such as NMP or benzyl alcohol. These strippers have low emissions, a pleasant citrus scent, and are biodegradable, though the stripped paint may not be. They work slowly but are effective.

Benefits:

  • Natural and biodegradable.
  • Pleasant citrus smell.
  • Effective on a wide range of paint types.

Limitations:

  • It can be slower to work than traditional strippers.
  • It may require multiple applications for thick or stubborn paint layers.

Popular Brands: SoyGel and Citri-Strip

Caustic Paint Strippers

Caustic paint strippers use lye, which is also found in soap. Though caustic, they are not necessarily toxic. The main risk is skin and eye contact, as inhalation toxicity is minimal. These strippers are water-based, using either potassium hydroxide or sodium hydroxide to break down paint into a soapy substance. They are environmentally friendly, neutralized with water and vinegar, and best for oil-based paints on masonry surfaces. However, they don’t work on epoxy and polyurethane and can damage some metals and wood.

Benefits:

  • Highly effective at removing multiple layers of paint.
  • Environmentally friendly when neutralized with water and vinegar.
  • Cost-effective, often cheaper than other paint strippers.
  • No VOCs, leading to better indoor air quality.

Limitations:

  • It can cause severe skin and eye irritation and requires protective gear.
  • It is unsuitable for all surfaces; it can damage aluminum and darken certain woods.
  • It won’t work on epoxy or polyurethane coatings.
  • Requires careful application and cleanup, which can be time-consuming.

Boiling Water & Baking Soda Paint Remover

Besides the paint strippers mentioned above, you can also use baking soda and boiling water as a safer alternative to traditional paint strippers. It is a simple, non-toxic way to remove paint from metal or hard plastic items. It’s safe and easy to do at home.

Instructions for Metal:

  1. Place your metal hardware in a pot of boiling water.
  2. Add baking soda.
  3. Boil for 30 minutes.
  4. Remove and lightly scrub the item.

Instructions for Plastic:

  1. Bring water and baking soda to a boil.
  2. Remove from heat.
  3. Add the plastic items into the solution.
  4. Soak for 5 minutes.
  5. Remove and gently scrub the item.

Alternative Method for Metal:

  1. For a few hours, boil rusty or old painted fittings in a 50/50 mix of Linseed Oil Soap and water.
  2. Let it cool overnight.
  3. Remove the fittings, brush them off in clean water, and leave them to dry.
  4. Capture old paint sludge and dispose of it safely.

This method breaks the bond between the paint and the metal or plastic, making it a very effective and completely non-toxic option for removing paint.

Using eco-friendly paint strippers is straightforward, but following a few key steps and safety measures will ensure the best results and your safety.

1. Preparation

Clear the area of any furniture and cover the floor with a drop cloth. Wear protective gear such as gloves, goggles, and a mask. Even though you will use a safer paint stripper, it’s still important to use these protective gear to protect your skin and eyes and to prevent inhaling harmful fumes. 

Then, ensure proper ventilation. Open windows and use fans to ensure good air circulation. If working indoors, consider using an air purifier to help reduce any lingering fumes.

2. Application

Apply the paint stripper generously with a brush or sprayer. Allow the stripper to sit for the recommended time (usually several hours or overnight for stubborn paint). Follow the manufacturer’s instructions for the best results.

3. Removal

Use a plastic scraper to remove the softened paint gently. For detailed areas, use a brush or steel wool.

4. Cleanup

Wipe the area with a damp cloth to remove any residue. Properly dispose of the removed paint and used materials according to local regulations.
