I have had a home of my own for 22 years, been married for 20 of those and have quite old children.
However, I am embarrassingly clueless about some elements of housekeeping. While I do change the bedlinen (even I am not quite this filthy), I don't really know what you're supposed to do to keep the actual pillows and duvets clean. To be truthful, every now and again, I just crack and buy some new ones in IKEA. Surely there must be a better way?
Also, I have no idea why I don't know this stuff - my parents' home is immaculate. I was a very studious, bookish child: this was greatly lauded and encouraged and I wasn't ever shown how to do practical things (e.g. figured out for myself how to clean a bathroom when I bought a house.)
Advice from more capable people would be great.
