FAQ - questions and answers.
What is EDTA?
EDTA is ethylenediaminetetraacetic acid. It is used in detergents and cleaning agents to soften water. EDTA is poorly biodegradable in sewage treatment plants. It can dissolve toxic heavy metal salts from the sludge is then fed perhaps even into our drinking water. Therefore, we have never used EDTA in our products.
Doing laundry: How to do it right?
Why is it so important to load the washing machine right?
The amount of water and the amount of detergent are designed for a correct load size. Too low of loadings can result in the detergent being overdosed. This leads to detergent residues, gray wash and skin irritation.
Overcharging is bad for the machine because the ball bearings etc. are not designed for it and will be worn early.
More tips on how to do laundry right is summarized in our laundry fibula.
Do you need special detergent for colored fabrics?
Coloured fabrics differ from heavy-duty detergents especially by the low content of bleach. In addition, color detergent does not include any brighteners as they can lead to color changes. So that the laundry's colors remain rich and vivid, most colored fabrics have additives, so-called color care agents and dye transfer inhibitors.
If you permanently use colored fabrics for white washing, they will degray by the lack of bleaching agents and optical brighteners.
You can find more information in our wash fibula.

How to remove grease and oil-based stains, for example, fat splashes, sauce, make-up and machine oil stains and water marks on shirt collars?
For this kind of stains, we recommend spraying havon FS in an undiluted form on the dirt or stain edges. In case of kitchen grease on white cotton, for example, chef's jackets, you can use RADIKALIN instead of havon FS. Let it work for about 15 minutes and then wash as usual. Alternatively, you can use havon V8 detergency boosters in the prewash dose. Please refer to the fabric care symbols.

How come my laundry is grey and hard?
Gray, scratchy laundry indicates calcium deposits. You can avoid calcium deposits when you dose the detergent correctly and also use a softener such havonCALC in case you have hard water.
To avoid detergent residue, you dose the detergent exactly as prescribed and load the machine correctly. A capped back of the hand should fit between the inner wall of the drum and the laundry. Also, have the manufacturer of your washing machine check the level of water and increase it if necessary.
You have to decalcify so that your gray, hard laundry will become white again: Place your laundry in a ten-percent ecosol DESCALER solution (100 milliliters ecosol DESCALER and 900 milliliters of water) for at least two hours. Alternatively, you can descale directly inside the washing machine: A 4-5 kilogram machine needs a liter of ecosol DESCALER. Wash your laundry at 60 degrees Celsius. You not only descale your laundry, but also the washing machine and heating elements.
How do I dose my washing powder correctly?
