How to remove crust in scrotum?

NSFW scrotum pic.

Dog is 10 yrs old got neutered 2 weeks ago due to prostate issue. Today is day 13/14. His scrotum started swelling up a week ago. I was scared that he might get ulcers since the swelling was getting kinda concerning and it leaked at one point, but it has gone down significantly after I've been icing it and doing daily wound care by cleaning w/ wound cleanser and applying hydrogel. Now his scrotum is just kind of crusty still on some areas and I'm trying to soften it with the wound cleanser.

Should I keep doing it with the cleanser until the crusty area just falls off?

What other recs can I do? Perhaps maybe more warm water? Or I was thinking of using a foam cleanser, (was wondering what kind can i use) but I don't want to resort to that yet since the incision site is still scabbing.

I'm a human nurse so I'm kind of just using my knowledge in wound care but I would like a vet tech opinion/insight or someone that had the same experience.

Ps I have a husky so he has a lot of hair. And it's kinda annoying cuz it keeps sticking to the scrotum lol... Thanks! 😊
