I agree with the cornstarch now that you mention it. It is baby powder with corn starch and I rarely use it - just used to keep the area dry. I think I will get some of that powder for jock itch (which is what it really is). I may react to that as I do a LOT of stuff but worth the try.
As for laundry, clothes, etc. - I use cotton mostly, no scented products at all including unscented fabric sheets. I am sure if I showered every day and used the powder when problem is dormant it would help. BUT - my other skin problems - soooo dry,etc. I cannot shower every day - every third day and wash my hair. I don't use any soap directly on those areas and I rinse thoroughly. I have dealt with this for many years off and on and it is mostly because of my obesity and folds of fat - have to be honest here!
