PG / VG as a cleanser?

[koopatroopa]

I've read that PG/VG is used to sterilize things. I don't really know how accurate this is but what if vaping is actually cleaning our lungs/sinuses? I feel like I don't get sick as much when my co-workers and friends do but that could just be from not smoking analogs. Has anyone heard or read into this type of thing?
