I thought I responded to your post but I don’t see it?? Thank you for the information about the tunnel blowers. I’m going to look into getting heaters to blow hot air towards the dryer intakes. At this point it seems like the easiest solution. As long as we can get the air temp above 45 the streaks and spots won’t happen.

I would bet you are getting water in the dryer housing during the wash and that dirty water is getting blown on the car. During hot Utah summers it evaporates before the dryer comes on. I had this happen to a customers car after I had just finished washing the bay down. I sent him through and forgot I hadn't kicked the blowers on to blow the water out. His car looked just like your pictures.

One last thought - if it is condensation on your blowers. Are your blower housings and ducts plastic or metal? I would think your chances of getting condensation would be greater with metal, and also pose a bigger chance of generating some type of sediment when condensation forms on the blower if it is metal.
We thought that could be a possibility too, so several times over the last couple decades we’ve wash out the dryer housings to see if that would help but it didn’t change the white streaks and spots. The only thing that ever gets it to stop is temperature. The dryers in this particular location are pretty far removed from the washing process too. Our other dryers at the other locations are real close and get some moisture in them - but they don’t have the streaking/spotting issue. It seem to definitely be something unique in this locations water, but we have no idea what.

Not sure of your setup, but it be condensation on underside of the roof in the bay. As temperature increases the condensation burns off and doesnt drip onto the surface of the car. I know it happens from time to time in my self serves especially since i run hot water.

That sure looks like chemical. Put a piece of pH paper on it before it dries.
Could a cold weather blowdown be purging out residual chemical in a line? Disable any freeze protection blowdown feature and try a wash.

Do you switch over to hot water for anything at 45? If so, it could be your water heat source.
Ok, THIS is an intriguing thought. In this particular location, the dryers are inside of the bay and the dryers are located directly beneath the open garage door (the door stays up during the wash cycle in the winter and closes after the car exits). Since this doesn’t happen at our other locations where the dryers are located on the outside of the building, you may be onto something. Now I’m wondering if it is condensation from not only being insude of the bay, but from also being in close proximity to the door panels above it since the door is in the up position. The dryers and door are far enough from the wash equipment that there’s no drips coming off of them - they stay dry. BUT, there plenty of humidity in the air from the wash cycle. It’s not like our exterior mounted Dryers that are pulling air from outside the bay.
