We are clear about the resistance performance of our doors. All common detergents and polishes currently widely available have been the subject of stringent lab tests. GD Dorigo assures that when used correctly, the detergents listed as positive in the test report will not ruin the surface of the door. Nevertheless, the use of bleach is not recommended. Furthermore, further tests have proved the seal on packaging, resistance to abrasion and to sharp rises and drops in humidity.

The GD Dorigo system is all this and more: quality and safety are built one day at a time.
