Is vaseline good as solder flux?

Could you elaborate on the feasibility of using Vaseline as a substitute for solder flux? While Vaseline is a petroleum jelly commonly used for skin care, I'm curious to understand if its composition could potentially aid in the soldering process. Solder flux, on the other hand, is specifically designed to remove oxides and impurities from metal surfaces, ensuring a strong and reliable solder joint. Could Vaseline potentially offer similar benefits, or would it pose risks such as contamination or reduced conductivity? I'm interested in hearing your thoughts on this unconventional approach.
