Hygiene issues because he hates being wet

For a while, I could get my DH to shower every few days and he had no trouble doing so on his own. I just needed to remind him to use soap and shampoo. A few months ago, he just absolutely refused to go into the shower. He said he didn't need that anymore, it was too small, stuff like that. So I bought some microfiber washcloths, no-rinse soap and no-rinse shampoo. He HATES being wet (says it's cold) so I get the water very warm and try to get some parts washed when he's in a good mood but it's really getting harder and harder. He is not cooperative and leaves the bathroom in a huff before I can get very far. I have the towel right there ready to give him after I wash each arm or leg, but he just gets angry. He's itchy a lot and his skin is getting flaky on his arms and legs (which usually prompts me to try to wash them). He still shaves (with help) so his face gets cleaned and I can get him to use deodorant. I'm just stuck as to what to do to keep him clean without it being a fight.
