DIY Hand Sanitizer – Easy, Cheap, Effective

Hand sanitizer can be expensive or sold out when you need it most. Making your own takes 60 seconds and costs pennies. This guide uses the World Health Organization (WHO) formula for maximum effectiveness. Two ingredients. No fancy equipment.

The WHO Formula: What You Need

  • Isopropyl alcohol (99% concentration – do not use lower)
  • Aloe vera gel (pure, no additives)
  • Optional: 5-10 drops essential oil (tea tree, lavender, peppermint for scent)
  • Small squeeze bottles for storage
  • Funnel

Step-by-Step Instructions (60 Seconds)

  1. Pour 2/3 cup isopropyl alcohol (99%) into a bowl or measuring cup
  2. Add 1/3 cup aloe vera gel
  3. Add 5-10 drops essential oil (optional, for scent)
  4. Whisk or stir until fully combined
  5. Use a funnel to pour into small squeeze bottles

Why These Ingredients (According to WHO)

The WHO recommends hand sanitizer with at least 60% alcohol to be effective. This 2:1 ratio of 99% isopropyl alcohol to aloe vera creates a final concentration of approximately 66% alcohol – well above the minimum. The aloe vera prevents skin dryness.

What NOT to Use

  • Do not use 70% isopropyl alcohol (final concentration will be too low)
  • Do not use vodka or drinking alcohol (not strong enough)
  • Do not use any alcohol below 60% (ineffective against viruses)
  • Do not use moisturizers or lotions with additives (interfere with alcohol effectiveness)

How to Store Your Hand Sanitizer

Store in small (2-4 oz) squeeze bottles. Do not use large containers (alcohol evaporates each time you open). Keep away from heat and flames (alcohol is flammable). Do not store in cars during summer (heat degrades effectiveness).

How Long Does Homemade Hand Sanitizer Last?

Properly stored in sealed containers away from heat and light, homemade hand sanitizer lasts 3-6 months. Check for separation – if separated, shake or stir to recombine. If the smell changes or becomes weak, make a fresh batch.

How to Use Hand Sanitizer Correctly

Apply a dime-sized amount to the palm of one hand. Rub hands together, covering all surfaces including between fingers and under nails. Continue rubbing for 20-30 seconds until hands feel dry. Do not wipe off excess – let it air dry.

When Hand Sanitizer Is NOT Enough (Wash Hands Instead)

  • Hands are visibly dirty or greasy (sanitizer does not clean dirt)
  • After using the bathroom (soap and water required)
  • Before eating (soap and water preferred)
  • After handling raw meat (soap and water required)

Conclusion: 2 Ingredients, 60 Seconds, Protection

Making your own hand sanitizer saves money and ensures you never run out. Keep a small bottle in your car, bag, and desk. With 2 ingredients and 60 seconds, you have effective protection wherever you go.
