And here I'm wondering what he used for the enema vessel. Hydrochloric acid absolutely wrecks plastic in no time at all, it does significant damage to metals fairly quickly as well. I'm going to assume it was glass.

Polyethylene, polypropylene and Teflon aren't damaged by hydrofluoric acid. Enema bags are commonly polypropylene, so he may not have used anything special, just the glass etching kit and the enema bag he already had to make an arse etching kit

Eats glass too.

Mild steel self passivates in HF but damage that layer at elevated temperatures & you can get a metal flourine fire.
