A BAD CAR WASH

2010 Hyundai Elantra • 3,100 miles

If you get a bad car wash from a drive through machine and it leaves streaks that you can only see in a certain light (Light shining through from behind while the car is in the garage), will those streaks always come off with a proper car wash? I believe the streaks to be from water though it could be that there could be some dried soap mixed in there (though I doubt that.) Does it matter?

Wash it by hand to see if the streaking comes off. I never really heard of a "bad" car wash. You might ask the operator at the car wash. They usually rinse with clean water, then dry by blowing air over the car to prevent accusations of scratching the paint with power towels and rotating brushes. Hand waxing will help too. It will promote the water beading up and running off along with any detergent that might be in it.

This was just a drive through car wash at a gas station. The blow drier is on a timer and it doesn't give you enough time to get your entire car dry. It leaves streaks. However, these streaks will come out. I was planing on having my car waxed soon anyway. This should prevent any further issues. However, no damage done. I can do a proper car wash on my own and it will come out clean, yes?

Yup. If the streaking is due to leftover detergent or from minerals in the water, that will even cause streaking with hand washing. Hand drying will reduce that tendency but you have to be careful to not "find" any sand or dirt that can get caught in the rag and scratch the paint. Even if the blow drying lasted longer, it's still just pushing water around that will leave trails of residue. There's no real good way to avoid that other than with hand wiping. That's why you see some people at old cars shows meticulously examining every square inch of their car looking for that. It's also one of the many reasons I let my "new" car sit in the garage and prefer to drive my old rusty trusty '88 Grand Caravan. It has never gone through a car wash since it was new. I just let the rain do its thing. My old new car with 4,200 miles gets hand washed and waxed, then parked back in the garage out of sight. Hmm. What good is a car you won't drive?

Oh well. Keep in mind too that another source of spotting is from rain. We always hear about acid rain but that isn't nearly as big a deal as it was many years ago. Still, any water from any source that isn't hand dried will leave some hint behind that it was there so I wouldn't be too hard on the car wash. If it was free, just accept it and rinse your car again at home, then hand dry it, at least in the areas you'll see. If you have to pay for the car wash, save your money and wash it at home. I don't even use detergent on my new car. I just surprise it with lukewarm water and a rag, then lots of buckets of clean warm rinse water. I do get spots but it doesn't take long in storage before the dust hides them!
