I get what you're saying and I think it's good that you try. It's like the stereotype that only women clean or are good at cleaning but if someone previously uninterested in cleaning finds a spot on something they care about eg. upholstery, car exterior, hand bag, furniture, etc male or female, they will want to know how to remove it properly without doing any damage and suddenly be very interested and eager to learn, albeit some would prefer to pay someone else to handle it. For many people certain topics including car care and maintenance just doesn't seem relevant enough until something happens despite the benefits of knowing about things that affect your life on a regular basis.
