500 g washing soda (sodium carbonate)
-
250 g baking soda

Equipment Needed

Large pot (at least 5–6 liters capacity)
-
Large bucket or container (30 liters capacity)
-
Grater
-
Wooden spoon
-
Measuring jug
Step-by-Step Instructions
-
Grate the Soap
Using a kitchen grater, grate the 400 g of white bar soap into fine shavings. The finer the shavings, the easier they will melt. -
Heat the Water
In a large pot, pour 4 liters of water and heat it over medium heat. Do not let it boil. -
Melt the Soap
Add the grated soap to the hot water. Stir continuously until the soap fully dissolves. This may take 5–10 minutes. The mixture will look slightly thick and creamy. -
Add Washing Soda and Baking Soda
Once the soap is completely melted, slowly add the washing soda and baking soda. Stir thoroughly until fully dissolved. -
Transfer to a Large Container
Pour the hot mixture into a large bucket or storage container. Add the remaining 20 liters of warm water gradually while stirring. -
Mix Well
Stir the mixture for several minutes to ensure everything is evenly combined. -
Let It Rest
Cover the container and let the detergent sit for 12–24 hours. During this time, it will thicken into a gel-like consistency. -
Final Stir
After resting, stir the detergent again. If it’s too thick, you can add a little more warm water to reach your desired consistency. -
Add Fragrance (Optional)
Add lemon essential oil or another scent of your choice and stir well.
How to Use
Use approximately:
-
150–200 ml per regular load
-
250 ml for heavily soiled laundry
Shake or stir before each use, as homemade detergent can separate slightly.
Extra Whitening Boost
For even brighter whites, add one of the following directly into the drum:
-
1 tablespoon baking soda
-
1 tablespoon oxygen bleach
-
½ cup white vinegar (in the softener compartment)
These natural boosters help maintain brightness and remove stubborn odors.
Storage Tips
Store the detergent in sealed plastic containers or large bottles. Keep it in a cool, dry place. Properly stored, it can last several months.
Important Notes
-
This detergent works best in warm or hot water.
-
For cold washes, dissolve the detergent in warm water before adding it.
-
Always test on delicate fabrics first.
-
Avoid using on wool or silk.
