I have a Bosch washing machine, I set teh temperature at 30 and teh RPM at 800, and my clothes comes out looking worn.
I use liquid detergent and a Calgon Tab.
Clothes look terrible.
Depends on the soiling on the clothes but tbh I will only use a good quality powder and would never wash anything at 30C unless it was more or less clean and just wanted a freshen up. I use green box Ariel for whites etc and purple box powder for coloureds. Minimum temp of 40C for colours and 50 to 60C for whites.
Hey. Try changing the detergent and rinse aid, this is probably the reason. I came across a similar and after replacing the detergent everything is fine.
