Important note: durgol forte does not contain any corrosion protection and is therefore not suitable for use in conjunction with metals. In these cases we recommend durgol universal. Before using durgol forte, be sure to observe the warnings on the product label. Always use durgol forte cold. 

Removal of cement residue; i.e. final cleaning by acidification as a last step when laying panels, after curing of the sealant, and to remove limescale or efflorescence. Before starting, wet joints and highly absorbent panels thoroughly with cold water. Dilute durgol forte at a 1: 3 ratio (durgol: water). Apply the solution evenly with a cloth or brush, then leave it to act for five minutes. Do not allow the solution to dry. Thoroughly scrub the surface. Rinse immediately with plenty of cold water. Rinse the cloth or sponge frequently and always use clear water. Repeat if necessary. Allow to dry completely. When treating larger surfaces, work on sections of max. 4 m2 at a time. One 1,000 ml bottle of durgol forte cleans an area of approximately 20 m2 to 60 m2, depending on the level of contamination.

Removing limescale: use cold water to moisten the clay pot thoroughly. Dilute durgol forte at a 1:1 ratio (durgol: water). Pour the solution into the pot so that it covers all the limescale. Leave to act for up to 30 minutes. To dissolve external limescale residue, place the pot in a larger container and proceed as described. Then rinse the container thoroughly with water.

Removal of stubborn limescale and urine sediment (yellow streaks) Add approx. 3 dl to the water in the toilet bowl. Leave the solution to take effect for as long as necessary; brush and flush. If there are yellow streaks or particularly stubborn residue in your toilet, apply durgol forte using a soaked cloth, allow the product to take effect for up to 30 minutes, then brush and flush. If necessary, also descale your cistern (attention: if the cistern has metal screws, use durgol universal instead of durgol forte).

E.g. heavy limescale deposits on exposed bricks, on facades or concrete structures, in fountains, on stairs, in car washes.

Frequently asked questions 

durgol products have a shelf life of 3 years from the date of manufacture. 

The more limescale that has accumulated, the more descaling solution is needed. If the limescale does not dissolve completely during use, this means that not enough descaling solution has been added and the acid agent has been used up. In this case, simply add a little more descaling solution and let it work again until the limescale is completely dissolved. As our descalers have a very high limescale dissolving power, we recommend a sparing dosage, which should only be increased if necessary.

durgol forte does not contain any corrosion protection and is therefore NOT suitable for use in conjunction with metals. In these cases, we recommend durgol universal or durgol universal bio. Observe the warnings on the product label before using durgol forte.
