Can someone help me

I know this sounds bizaare, but I have a phobia of soap. Dont get me wrong, I am a clean person, i shower, clean my house, bathe my kids, but when it comes to soap, it has to be rinsed off or I cant stand it. I feel if I have soap on me i will itch and it will just keep getting on everything. If someone dont rinse their hands good I dont want to touch anything they touch or let them touch me because I feel it will transfer. I make my kids rinse their hands when they get home from school fearing someone didnt rinse their hands good at school and there was still soap on the sink knobs and my kids have soap on them now and it will get all over everything at the house and me. If i buy shampoo, cant have anything on the bottle. It has literally taken over my life! WHen I take a shower I have to be sure and get all the soap off me. When I do laundry I am afraid not all the soap got rinsed out of my clothes. If I pick up a bottle of soap and it is slick like soap on the outside I have to rinse it off. If I see something that looks like soap on something, I assume it is and freak out. Please, someone help me, I dont want to put my kids and husband through this torture anymore of making sure all the soap is rinsed.

A quick reply - Maybe a form of OCD ? Do you have any bad memories from childhood, such as your parents washing your mouth with soap?
