People having permanent press
I think most humans are much like you, they have garments and sheets labeled "permanent press" but wash and dry them like any other garment without second thought and without resulting problems.
Personally I look at something and ask myself, does this need delicate or normal and sort it from there. Regular cottons and sheets hot water, warm for casual items and cold for delicate. A lot of 3button coin op washers seem to be set up that way.
