kettles, filter coffee machines, saucepans, frying pans, shower heads, nozzles, tap filters (jet regulators), fittings, vases, toothbrush glasses, baby bottles, sinks, chrome steel troughs, aquariums, etc.

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.

Containers

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.

Flowerpots

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

Tap filters (jet regulators), shower heads, nozzles

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

Electrical appliances

Examples:
filter coffee machines, air humidifiers, etc.

Please read the manufacturer’s instructions.

Important information

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.

FAQ

Frequently asked questions

What is the difference between durgol universal and durgol universal bio?

durgol universal is characterized by its particularly rapid effect and powerful descaling performance.
durgol universal bio also dissolves limescale reliably, but it is even gentler on the environment. Our durgol universal bio is biodegradable at a rate of >99.5% within 18 days making it the more environmentally friendly variety. This ecological added value is regularly tested and confirmed by the renowned SGS INSTITUT FRESENIUS. durgol universal bio dissolves limescale at a slightly lower rate than durgol universal. Most consumers will not notice a difference between the two products.

What is special about durgol universal bio?

In addition, durgol universal bio is free from unnecessary substances, such as perfumes, dyes and preservatives.
The classification “readily biodegradable” is the highest grade of biodegradability. It is regularly tested and confirmed by the renowned SGS INSTITUT FRESENIUS.

A powerful cleaning product that does not harm the environment? Is that possible?

During the development of the product, we attached particular attention to achieving a fast and gentle, yet powerful descaling effect. Strict regulations made this task extremely difficult. But we succeeded. The result is a product that is as powerful as other descalers, while also in compliance with all required environmental criteria.

How do I dispose of durgol products?

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.
