I don't have a reason to go to a laundromat...
...nor would I want to. Germs, grime and crud galore. I'd have to run a bleach cycle on empty on any washer I would use, and use a heavy-duty degreaser to remove baked-on grime, skin oil residue and God knows what else baked on the drum of the dryer. The fact that commercial dryers can kill most bacteria does not assuage me. It would be a chore in of itself, hence my name 'superocd'.
However, I would take time to stop at an old laundromat to use old the old Wascomat W1xx series. I love it when the relays click into the spin cycle and the big whistle it would make when it would spin down. I would feel especially happy if I could use an old Hoyt, Troy Laundrite ("Big Boy"), Cook Aldwash/Aldry and a plethora of pre-1980s machines that are simply not around any more.
I was a 90s kid but I feel like I've missed out on some pretty interesting machines. I only went to the laundromat three times a year, when we washed bedspreads and curtains that would not fit in our GE Filter Flo at home. The machines there were the ubiquitous 1980s Wascomat/Huebsch Loadstar combos. The new computerized Alliance/Wasco/etc. stuff, while good, is pretty boring -- every laundromat has these now. I guess they kind of have to because parts are probably nonexistent for older machines, as are many of the manufacturers, and they are certainly not water and energy efficient. The washers filled way above the glass door and had no sensors to determine how much water to use and the dryers had standing pilots and ran hot.
