A wash concentrate for our linen Workwear, the denim and everything else in cotton. Plant fibres are rough up close. Cotton & Linen Care lets them swell in the water, so a small amount of detergent is enough to lift the dirt. No optical brighteners, no bleach. Colours stay bright, and the old trick of vinegar in the last rinse becomes unnecessary.

Made for us by a textile care specialist in Mönchengladbach who has produced this formula for denim houses for years. The bottle is clear, 100 percent recycled PET with a white cap. 240 ml lasts about 24 hand washes or 12 machine washes. 50 ml is the size that travels.

Safety: Attention. Causes serious eye irritation. Keep out of reach of children. If in eyes: rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. If eye irritation persists: get medical advice or attention. If swallowed: call a poison centre or doctor if you feel unwell. The UFI code and the full label text are on every bottle.
