How could it possibly solidify
whilst under a jet of water?

Something's not right here.

Not all of it did, but using cold water is the best way to get rid of manfat from the skin. Hot water somehow is a recipe for disaster.

Try it yourself - for best (worst) results spaff over your own hairy chest and see what happens when hot water is involved.

Science time
Protein denatures and coagulates when heated. You know how egg white goes solid and opaque when you cook it? Same principle.
