Do Not Understand All This Palaver About Soaking
Bung even the most filty soiled wash into the Miele, add Persil, or my European commercial washing powder for colours, and perhaps some extra oxygen bleach if required and set the washer for either 100F,120F, or 140F and that is that.
Wine,tomato sauce, curry,blood, the lot come out spotless with 99.9% of stains shifted.
Only time one soaks anything is either for vintage fabrics that shouldn't be banged about too much, and fragile textiles for the same reason.
Tried soaking some stained dinner linens once in the Miele, using the dedicated cycle for doing so. Cycle ended and one drained out the water, linens were that clean they only required rinsing and spinning out. Never bothered with a soak as a prelude to washing ever again.
Certinaly wouldn't soak anything in LCB laden water for several hours. It just isn't required and probably does more harm to textiles than anything else.
LCB whitens and removes stains in about five minutes, less if the water is >120F. Longer contact time does not improve results and indeed any stains not shifted within say <10mins aren't going anywhere. This is one of the reasons commercial laundries have a separate but short bleach cycle (usually the first rinse), and not part of the long wash cycle.
