I use white vinegar cca. 1dl. I pour it after first water intake and I put detergent between first and second water intake.
I noticed better stain removal, color retention and smell improvement.
I may be under the influenece of placebo effect, but to me laundry seem to be washed better with addition of vinegar.
got it bundled in Jazz Jackrabbit Collection form GOG’s Christmas sales
so much nostalgia
