Is that steam or degreaser....

[Gone in 60]

Here's a fun little video that's making the rounds in the Royal Enfield community. 
It details a "major service" of an Enfield twin, which mainly seems to consist of blasting something at parts of the bike that would not normally like that.

Question is, what exactly is he shooting at the wet side of the engine and bearings... steam, degreaser?
