I'm kinda thinking (backed up by years of doing it) that Vinegar won't explode.
from wikepedia
Solutions at more than 25% acetic acid are handled in a fume hood because of the pungent, corrosive vapour. Dilute acetic acid, in the form of vinegar, is practically harmless. However, ingestion of stronger solutions is dangerous to human and animal life. It can cause severe damage to the digestive system, and a potentially lethal change in the acidity of the blood.
Due to incompatibilities, it is recommended to keep acetic acid away from chromic acid, ethylene glycol, nitric acid, perchloric acid, permanganates, peroxides and hydroxyls.[65]
Concentrated acetic acid can be ignited only with difficulty in the laboratory, but becomes a flammable risk in ambient temperatures above 39 °C (102 °F), and can form explosive mixtures with air at higher temperatures (explosive limits: 5.4–16%).
So it probably won't burn or go bang.
It definitely does clean bike bits up.
go on,.......live life on the edge.......
