I can relate - try a "clarifier" sold in hair care isle
I know the feeling or maybe I should say "I know the smell". It's amazing to try all types of products, some with "scrubbing bubbles" (actually that's a bathroom cleaner) but you probably get my drift -- nothing helps.
I can't say this enough, clarifier worked for me. It's marketed for removing heavy metal and chlorine build-up. Hair stylists are aware of this product and it's marketed to swimmers too.
I found some at Walgreen's in the haircare isle and I also bought some at the hair salon I go to. Some of the products have a really "acrid" smell and others don't. The stuff I like best I got at the salon was a Nexus product that has three items in this type line. There's a 1) clarifier solution, 2) a clarifing shampoo and 3) a clarifiing conditioner. There's all kinds of products like this out there.
I usually use the shampoo or clarifier all over my body with great results but last week I put a big glob (maybe 3 tablespoons) into my "soak in the bathtub night" bathwater. I just sat and soaked for a half hour (gave myself a pedicure while I was at it). I got the best results that way.
Let me know how it went. It's a fairly inexpensive, quick thing to try.
I've posted a lot on this and other "odor" subjects in the last month or so. Good luck and let me know what you think.
