Why the Frigidaire may not have removed the stains....
For a few summer I was washing my white T-shirts in a Frigi '62, with the standard 3 ring agitator. The typical stains were berries, chocolate, and tomato sauce, and they always washed out. Then I bought a new Energy Ring, aka big bottom fin, from JoeL. These fins are smaller, visibly so. These are the same fins found on the Jetcone agitator which is the one inside the machine in the "Which " test . When I switched fins this summer, I hung the shirts on the line, stunned to find some of stains still there, muted but visible.
Nothing changed. I still eat dark chocolate (Lundt Intense Orange) berries and home-made spaghetti sauce often, still spill sometimes ;'D, use the same detergent, Tide with Bleach Powder, same procedure. Fill machine, agitate for a few minutes, pull the dial out for a soak (30 -40 minutes), then resume the wash period from where I paused for the soak.
So now, I soak longer and turn the dial around for another full wash period, just before the first overflow. And the stains come out. I tried never spilling, but it didn't work. ;->
Findings: the smaller fin does not move the clothes as fast. Nor does it hit as hard since it is more bell-shaped and does not flatten out the way the standard one does. The advantage though is that there is no tangling, no matter how you load the tub. If you're not a challenged eater like me, you'd never notice the difference.
