🍋 Step 1: Prepare the Lemon
How to Prep Fresh Lemon
- Choose fresh lemons – Look for bright yellow, firm lemons.
- Wash the lemons – Scrub under running water.
- Zest the lemon – Use a microplane or zester to get 1 tablespoon zest.
- Juice the lemon – Squeeze to get ¼ cup fresh lemon juice.
- Strain – Strain the juice to remove seeds and pulp.
- Set aside – Keep the zest and juice separate for later.
💡 Pro Tip: "Organic lemons are best if you're using the zest, as you'll be adding it directly to the soap."
⚠️ Step 2: Safety First
⚠️ Important Safety Rules:
- Always wear gloves, goggles, and long sleeves when working with lye
- Work in a well-ventilated area
- Keep vinegar nearby to neutralize any spills
- Keep children and pets away from your workspace
- Use heat-safe containers – glass or stainless steel
- Never add water to lye – always add lye to water
📝 Step 3: Make the Soap
Step-by-Step Instructions
Prepare the Lye Solution:
- Measure 1 cup distilled water into a heat-safe container.
- Slowly add ¼ cup lye to the water while stirring. Do not inhale fumes.
- Let the lye solution cool to 100-110°F.
Prepare the Oils:
- In a separate pot, combine 2 cups olive oil, 1 cup coconut oil, and ½ cup sunflower oil.
- Heat gently until all oils are melted and combined.
- Let the oils cool to 100-110°F.
Combine and Blend:
- Stir ¼ cup fresh lemon juice into the cooled lye solution.
- Slowly pour the lye mixture into the oils while stirring.
- Use an immersion blender to blend until "trace" – when the mixture thickens.
- Stir in 1 tablespoon lemon zest and 1 teaspoon salt.
Mold and Set:
- Pour the soap mixture into molds.
- Cover with a towel and let sit for 24 hours.
- Unmold and cut into bars.
💡 Pro Tip: "Fresh lemon juice gives the soap a beautiful yellow color and a fresh, clean scent!"
⏱️ Step 4: Curing
How to Cure Your Lemon Soap
- Place bars on a rack – Use a wire cooling rack with good air circulation.
- Wait 4-6 weeks – This is essential for a mild, long-lasting bar.
- Turn occasionally – Flip the bars every few days for even drying.
- Test for mildness – After 4 weeks, test a bar on your skin. It should be mild and not irritating.
- Store properly – Once cured, store in a cool, dry place.
💡 Pro Tip: "The lemon scent will intensify during curing. Be patient – it's worth the wait!"
