Homemade performance with concentrated black soap
This DIY recipe was designed to provide real dishwasher effectiveness, while remaining simple and realistic for home use.
RECIPE – POWDER BASE (≈ 1 kg)
-
450 g sodium carbonate (washing soda)
→ Powerful degreaser, essential alkalinity for washing -
300 g sodium percarbonate
→ Active oxygen: stains, odors, tea, coffee -
200 g sodium bicarbonate
→ Stabilizes the formula, aids rinsing
Preparation
-
Wear gloves (alkaline powders)
-
Carefully mix all ingredients dry
-
Store in an airtight container, away from moisture
** Do not add black soap to this mixture.
➕ ADDING BLACK SOAP (AT WASHING TIME)
Use concentrated liquid black soap.
-
½ to 1 tsp (2 to 5 ml) per cycle
-
Pour directly into the detergent dispenser, over the powder
** Black soap acts as a degreasing booster (sauces, cooked fats), while remaining dishwasher compatible when properly dosed.
DOSAGE PER CYCLE
| Soil Level | Powder | Black Soap |
|---|---|---|
| Normal | 1 level tbsp | ½ tsp |
| Very dirty | 1½ tbsp | 1 tsp (max) |
**Tip: more black soap ≠ more effective. The right dosage makes all the difference.
RINSE AID (HIGHLY RECOMMENDED)
To put in the rinse aid compartment:
-
White vinegar or
-
Diluted citric acid (1 tbsp in 250 ml water)
Essential for:
-
avoiding white streaks
-
improving shine
-
neutralizing water minerals
IMPORTANT TIPS
-
✔️ Use a cycle ≥ 55 °C (activates percarbonate)
-
✔️ Clean the dishwasher filter once a month
-
✔️ Store powder in a dry place
WHY IT WORKS
-
The carbonate ensures mechanical cleaning
-
The percarbonate works deeply at high temperatures
-
The bicarbonate stabilizes and protects
-
The black soap, properly dosed, enhances degreasing without harming the cycle
👉 An honest, effective, and consistent approach for domestic use.
