Yesterday was coverlet/quilt wash day. As these are items that won't go in any of our front loading washers, and one didn't wish to faff about with Maytag wringer, off to local launderette one went.
Much as one dislikes the place it was lesser of two evils...
Thinking of this thread decided to take a peek at rating plate inside washer doors to see what Speed Queen series washers are installed. Apparently they are the "SCN" and happily lovely Florence Ballard has done us a video on YT.
Mind you as noted previously wash time is horribly short. For so called "Heavy" soil with "Normal" cycle and "Hot" water comes to over $11 USD for largest washer (IIRC 50lb capacity, maybe larger.
Of total cycle of 33 minutes (again this is less than displayed because at end of cycle there are several minutes left in display, but machine goes to "zero" and shuts off.
Pre-wash is about two minutes.
Main wash on "Heavy/Normal" is barely 6-7 minutes (machine began filling for main wash at 27 minutes, dumped wash water at about 23 or 24 minutes. Balance of time is spent on drains, fills, rinses, pulse spins, lather rinse and repeat until final rinse.
Place only has the one large machine and it's one those in the know go to because it has longest cycles and seems to rinse better. Smaller machines started at same time with same cycle selection finish sooner. Go figure.
As have said with such short wash time forget about using turbo charged enzyme technology or whatever detergents. There just isn't enough time. Less so because chlorine bleach is dispensed about one minute into wash.
One spends considerable amount of time either pre-treating or pre-soaking anything but the lightest soiled laundry before using these machines. That and coupled with commercial/industrial detergent in one's stash (yesterday was Ecolab Solid Super Star loaded with phosphates), seems to do the trick Will also use industrial laundry sour in final rinse (Ecolab Navisour).
For lightly soiled items find vintage powdered detergents work well enough. Have that stash of Cheer Bright Clean in coin vend sizes so that's me for you.
