In the trade there are specially designed products for curtain cleaning (colour protection, bleaching, delicates, etc. ) Pro Clean Concentrate is a replacement for all commercially available cleaning agents. It was not developed especially for curtains, but there are always very good experiences with textiles.
In general, Pro Clean Concentrate is very suitable for removing stains from clothing. Just try it out for yourself. Depending on the degree of soiling, add about 20 sprays of pure Pro Clean Concentrate to the detergent compartment or spray it directly into the washing drum. Also make sure that the laundry is colour-stable.
Pro Clean Concentrate is very suitable for hand washing and to pre-treat stains in the fabrics (please check colour-stables). The Pro Clean Concentrate gives the textiles a very pleasant, discreet scent.
