Stop Buying Laundry Detergent — This $0 Recipe Lasts a Year!

Key idea

• Replace store-bought laundry detergent with a DIY concentrated cleaning gel made from 3 inexpensive ingredients.
• Claimed cost: about $6 for roughly 1 year of laundry (about 300 loads).

Why detergent is expensive (the “markup” explanation)

• Most commercial detergent bottles are mostly water (about 90%), plus dye/fragrance.
• The actual cleaning surfactant is only a small fraction (under about 3%).
• Branding and fragrance encourage people to equate smell with cleanliness, even though cleaning chemistry doesn’t require scent.

Health/skin reasoning

• The DIY gel is described as:
  • Low-sudsing
  • Free of synthetic dyes, optical brighteners, and fragrance
• The speaker claims this may help reduce reactions such as:
  • eczema
  • baby skin irritation
  • migraines linked to scented detergents

Ingredients to buy (and where)

• Washing soda (sodium carbonate)
  • Example: Arm & Hammer Super Washing Soda (yellow box, ~3 lb)
  • Price: ~$4.99 at Walmart/grocery; ~$6 on Amazon
• Borax
  • Example: 20 Mule Team Borax (~4 lb)
  • Price: ~$5 at Walmart/Target/Home Depot
• Castile soap (for surfactant/grease cutting)
  • Example: Dr. Bronner’s Pure Castile Bar Soap (~$4.50 per bar)
  • Cheaper option mentioned: Kirk’s Castile (~$2 per bar)

Recipe / step-by-step method (bucket gel)

1) Grate soap

• Grate Fels Naptha soap into flakes.
• Target amount: ~1 cup grated soap flakes.

2) Melt soap

• Add 4 cups hot water to a saucepan.
• Heat on low and stir for about 10 minutes.
• Do not boil (boiling causes foam and can ruin consistency).

3) Mix in bucket

• Use a 5-gallon bucket (Home Depot sells orange ones mentioned; ~$3.50).
• Fill about halfway with hottest tap water.
• Pour in the melted soap mixture.
• Add:
  • 1 cup washing soda
  • 1 cup borax
• Stir slowly with a long wooden spoon for about 2 minutes.

4) Finish and cure

• Top off the bucket to full with cold water.
• Put on the lid and let sit overnight.

5) Result

• After about 12 hours, it becomes a thick, semi-translucent gel (“white gold”).
• Expected performance: about 300 loads (roughly 1 year for a family of four).

How to use (per load)

• Use about 1/2 cup gel per wash.
• Add it:
  • directly into the drum, or
  • into the detergent tray (for front loaders).
• Claim: it dissolves instantly in any water temperature.

HE (high-efficiency) machine notes

• The claim is that it won’t damage HE washers because it’s naturally low-sudsing.
• Supporting argument:
  • Many suds from synthetic detergents can clog drainage sensors.
  • This recipe uses soap chemistry instead, closer to what machines were originally designed for.
