Standard Instructions (Mix Fresh)

Step 1: The Base (1 minute)

  1. Place empty bottle on digital scale
  2. Tare scale to zero
  3. Add Distilled Water first
  4. Why: Adding water first prevents the alcohol from splashing out or evaporating during measurement.

Step 2: The Sanitizer (30 seconds)

  1. Pour in Ethanol slowly
  2. Watch the gram count carefully—precision ensures the 40% ratio

Step 3: The Surfactant & Scent (30 seconds)

  1. Add Dawn Dish Soap — be extremely careful not to squeeze. You want a single drop (1g).
  2. Add Tea Tree Oil (drops sit on top)

Step 4: The Mix

  1. Cap the bottle tightly
  2. Swirl gently in a circular motion
  3. Do NOT shake vigorously (this creates pressure and foam)
  4. Ready to use immediately

🧼 PRO MOVE — The "Flash Dry" Technique:

For a mirror finish on black quartz or granite:

  • Spray lightly (mist, don't soak)
  • Wipe immediately with a microfiber cloth
  • Flip the cloth to the dry side for a final buffer pass
  • The 40% alcohol evaporates instantly, taking any potential water spots with it

Troubleshooting

Problem Solution
Streaks appearing Too much Dawn used. Dilute with 20g more alcohol.
Smell is too medical Add 1g Lavender or Peppermint oil.
Spray nozzle clogging Use distilled water only (tap water minerals clog).
Oil floating on top Normal separation. Shake gently before each use.
Haze left on stone Dirty microfiber cloth. Switch to fresh cloth.

Final Notes

The Chemistry: Commercial sanitizers use 70% alcohol, which is great for hospitals but aggressive on stone sealants. Water-only cleaners don't disinfect. This 40% blend is the "Goldilocks" zone: strong enough to kill common kitchen bacteria, but gentle enough for daily use on expensive finishes.

The Physics: The ethanol lowers the surface tension of the water (along with the trace amount of Dawn), allowing the liquid to spread thinly and evaporate rapidly. This is physically what prevents "spotting" on quartz.

Why Distilled?: Tap water contains dissolved minerals (calcium/magnesium). When the water evaporates, those minerals stay behind as white spots. Distilled water is empty, leaving zero residue.
