[Kind of Gross] When I use a q-tip to clean my ears, I notice that gunky reside from the left ear is always darker and dirtier than the right. Is that from driving with the windows open?

In the US. the driver’s seat is on the left and I often drive with the windows open.

Is it likely that tiny dirt particles are flying into my left ear (moreso than my right), causing darker wax accumulation?
