As the natural passivated layer on stainless steel surfaces ages it can form a rust-red deposit known as rouging. Rouge is not acceptable under GMP regulations as surfaces with rouge deposits are not visually clean. The deconex® DEROUGE system removes rouge effectively at neutral pH-value. We also offer products which build up or renew the surface passivation of your equipment, which prolongues the life of the equipment and reduces the risk of production downtime. Regular maintenance protects your production equipment and so aids the retention of value. Due to long-standing experience Borer Chemie and Groesfjeld can provide precise cleaning processes for both derouging and surface passivation.
