Persil Color Deep Clean Laundry Detergent - 2.925kg (45 Washes) | Color Protection & Stain Removal | Perfect for Family Laundry & Activewear

The detergent does not have brighteners and does not fade dark clothes. I use it for warm washes at about 95/100F and it dissolves well, no problems. I do not have experience for true cold washes. It smells similar to Persil for whites (linalool) and it leaves a very mild smell after the drier (less than the US leading detergent). I use 30ml (2Tbs) for small loads and 60ml(4 Tbs) for full loads (half the recommended amount). The amount of detergent needs to be adjusted for hardness of water and amount of soil.
