Instructions

The correct dosage saves money and protects the environment. Depending on the amount of limescale to be removed, use the biodegradable descaler either undiluted or diluted with water at a 1:1 ratio.

Examples:
kettles, water jugs, saucepans, vases, flowerpots, pet food dishes, etc.

Depending on the quantity of residual limescale, fill the container with diluted or undiluted durgol universal bio so that it covers the limescale completely. Leave to act for up to 30 minutes. If the solution stops generating foam, but visible limescale is still left, the active substance is used up and you should add more durgol universal bio. Rinse thoroughly.

To dissolve external limescale residue, place the pot in a larger container and proceed as described above. Then rinse the container thoroughly with water.

Place in a container filled with durgol universal bio for up to 30 minutes. Afterwards, rinse with water.

Examples:
filter coffee machines, air humidifiers, etc.

Please read the manufacturer’s instructions.

Always use durgol universal bio cold. Do not mix with other cleaning or washing products. Use only on undamaged, acid-resistant materials. If in doubt, test on a concealed area first.

  • Tip: pour used descaling solution or any leftover product into your toilet bowl and leave it there until you next use the toilet. This has the following advantage: acid residue can dissolve limescale and urine sediment in the toilet.
  • All empty product bottles must be disposed of in domestic waste, even though all durgol bottles are similar to conventional PET beverage bottles. Unfortunately, manufacturers of products sold in PET containers but which are not intended for consumption are not eligible for membership of PET Recycling Switzerland. This means that the durgol bottles must be sorted out before the recycling process, even if they have been rinsed thoroughly.
