Homemade Liquid Soap for Laundry Without Spending a Penny

By Vitia

In today’s world, where both the cost of living and awareness of eco-friendly practices are rising, making your own household essentials can be a smart and sustainable choice. One such essential is liquid laundry soap. Surprisingly, you can make an effective and natural homemade laundry detergent without spending a single penny—by simply reusing and repurposing ingredients and materials you already have at home.


Why Make Your Own Laundry Soap?

Commercial laundry detergents often contain harsh chemicals, artificial fragrances, and unnecessary fillers that can irritate sensitive skin and harm the environment. By contrast, a homemade liquid soap is:

  • Non-toxic and gentle
  • Eco-friendly and biodegradable
  • Budget-saving
  • Customizable to your needs

What You’ll Need (For Free!)

You don’t need to go shopping to make this liquid soap. Here’s how to make it with free or reused materials:

  • Soap scraps – Leftover pieces of bar soap from your bathroom
  • Hot water – Straight from the tap
  • Used cooking pot or container – For mixing and storing
  • Essential oil leftovers (optional) – If you have any nearly empty bottles, even a few drops can add fragrance
  • Old blender or whisk – To help blend the mixture (optional)

Step-by-Step Instructions

  1. Grate or Chop the Soap Scraps
    Take your leftover bar soap pieces and grate or finely chop them to help them dissolve faster.
  2. Add Hot Water
    In a large container or pot, add the soap pieces and pour in hot water (about 4 cups of water for every 1 cup of soap). Let it sit and melt for a few hours or overnight.
  3. Stir or Blend
    Use a whisk or an old blender to mix the soap and water until it becomes a smooth, gel-like liquid.
  4. Add Fragrance (Optional)
    If you have any drops of essential oil left in old bottles, add a few drops for a natural scent.
  5. Store and Use
    Pour your liquid soap into an old laundry detergent bottle or any other clean container. Use about 1/4 cup per laundry load.

Benefits of This Homemade Soap

This simple recipe is more than just frugal—it’s a sustainable way to reduce waste by repurposing soap ends and containers. It’s safe for most fabrics and washing machines, and it leaves your clothes clean and lightly scented without the artificial chemicals.

You’re not only saving money—you’re also taking a step towards a more sustainable and self-sufficient lifestyle.
