Your Maytag is from the late 60’s to the early 80’s. My family bought one like this in 1969, and it was the first year that they used the “S” in the model number I believe. The “S” designated that it was a safety machine equipped with the pedal that the user needed to step on to keep the wringer on. The dealer we bought ours from suggested that we have him bypass this feature, as most of his customers disliked this feature. To do this he removed the rubber tubing from underneath the machine that the safety pedal was connected to and plugged the hole with a stove bolt, problem solved.
You can use any kind of detergent or soap that you like with this wonderful Maytag wringer. Some people say to not use chlorine bleach in the aluminum tub model, claiming that it will discolor the aluminum. We always used bleach, and I can’t recall that it ever discolored the tub. But it’s a washer afterall, if the bleach discolors the tub a little, it’s not the end of the world, unless you plan on selling a pristine machine at somepoint. Otherwise, enjoy using it.
