Yeah, laundry detergent prices are outta control lately. Plus, half the ingredients sound like they belong in a chemistry lab, not a washing machine. That’s why more people are switching to DIY versions. You save money and know exactly what’s touching your clothes and skin.
I have a homemade liquid laundry detergent recipe that’s incredibly easy and inexpensive. If you’ve wondered how to make homemade washing liquid, this guide is for you. I’ll share the basics, a few tweaks, and the details on how eco-friendly it is, what it costs per load (spoiler: it’s pocket change), and what to consider before trying your own DIY liquid laundry detergent recipe.
Benefits of DIY Liquid Detergent
Before jumping into the actual DIY liquid laundry detergent recipe, let’s examine why more households are making the switch.
Eco-Friendly
Store-bought detergents pack phosphates, which are terrible for aquatic life (Wikipedia backs this up). Switching to a DIY liquid laundry soap recipe is better for the planet no phosphates, no guilt, and no giant plastic bottles piling up at home
Cost Savings
This is where DIY detergent really shines. Store-bought brands like Tide or Persil can cost $0.25–$0.35 per load. A gallon of the homemade liquid laundry soap recipe works out to less than $0.10 per load. That’s real savings over hundreds of wash cycles.
Gentle on Skin
Store-bought detergents often contain dyes, fake scents, and preservatives no wonder your skin reacts. A homemade liquid laundry detergent recipe puts you in control: keep it non-toxic, skip fragrance, or add essential oils to make laundry day less boring.
Tip: Some DIYers (like lifestyle blogger Lauren) swap Epsom salt for kosher salt in their detergent mix because Epsom can react with hard water and leave residue. Small tweaks like this make your formula more customized.

In my experience, dump in enough washing soda so it actually blasts through those greasy stains. Don’t be shy about it. And if your skin freaks out at, like, everything, just ditch the borax. Keeps your laundry soap way less harsh, which is a total win for the sensitive-skin crew.

Cost & Performance Comparison
Here’s a quick breakdown:

That’s up to 70% savings. A Reddit user even mentioned, “I make a gallon at a time, and it lasts my family of four nearly two months.”
Disadvantages of DIY Recipes
To keep things honest, here are a few considerations before you switch:
- Some manufacturers claim DIY detergents can void washing machine warranties.
- If stored improperly, liquid detergent may grow bacteria or mold (use smaller batches if concerned).
- Results can vary depending on your water hardness and washing habits.
That said, thousands of households use homemade liquid laundry detergent recipes safely without issues.
