Hand washing vs drive thru car wash???
Are they bad for the car? Yes. Thats why I drive light colored cars. Carwashes will always cause scratches and wear to the paint and trim. My Pacifica is dark blue, and the paint is beat.
I just reach over and turn off the parking sensors.



* no waxing though! Thanks to the coating, I only need to apply a bit of a ceramic detailer afterwards which takes much less time compared to a wax procedure.
I also detail my cars so i'm next level OCD on appearance lol

It's actually nice to do cause you don't have to sit there for X minutes then get out pay and wait some more then go back home with that tire shine that comes off in 2 seconds whereas you sit home watch TV have your coffee and never move the car.

I don’t use them, but I think a drive-through carwash is fine if you detail the vehicle —2x/year. If you just use a carwash and never get the car detailed it will look haggard fast.

I vacuum every now and then; doesn't need any more than that, but I apply a leather cleaner and sealer every three months. That, I easily dread more than hand washing once a week. It's back breaking and takes 3 to 4 hours to do properly.

If you really have to use touchless, I recommend picking the least expensive option but at a state of the art facility, mainly because the least expensive ones use the least harsh chemicals and the state of the art ones at least hopefully don't use bad water/or badly recycled water.
The problem with all the soft-cloth/brush automatic washes is that it washes all kinds of vehicles, some full of mud or some with unsecured cargo that can get wrapped in the brushes which then damages your vehicle, for example this (this video might be painful to watch, it was for me so I placed it in a spoiler if you do indeed want to watch it, you may click it)

BTW, a German university did a study on hand washing vs. commercial car washes and they found that handwashing leaves more and deeper scratches even if done properly. The study was later confirmed by the University of Texas. Handwashing is not all what it's cracked up to be. Now it all depends on what kind of commercial car wash you are using. I wouldn't go to those gas station car washes. While I was in Europe on my European Delivery trip it was raining a lot for the first month and I took it to a car spa several times. Those are state of the art automated car washes combined with some hand pre-wash and then a station where you can do final drying using clean towels and vacuum the interior etc. Once the car arrived in the US I put PPF on the front half and the rear bumper, so the most exposed parts are protected and the PPF is self healing.
Ultimately, UV light and harsh weather does much more damage to the paint than an occasional wash.

No offense to car wash people, I just don't want to risk it, the swirls, but mostly, have to drive to one, wait in line, maybe for a longer time than I'd want to, and hope nothing goes wrong with the wheels getting messed up or the car getting messed up. Instead, I can wash my car at 11pm at night in the dark using the garage lights... it's fine. I'll be dead soon, I'm 62, in 38 years or less, I won't live forever, and this method works for me. I had the front PPF's and the whole car ceramic coated 5 years ago, still looks... new.
I putz around with my cars in the garage at night too, detail them etc...washing is just more work and mess than I want to deal with. I go around the car with some QD and a spray ceramic booster and detail the wheels and the interior and all after I've gotten it washed and it comes out perfect. But, if you shone a halogen light on it its swirled and all, but...thats why its white.
As to driving to a carwash, I stop on my way to and fro, thats the point.




A light paint will hide defects a lot better than a dark paint, metallic paints will also hide defects better than solid.
A solid black car going through traditional brush carwash will look pretty bad after 2 yrs, same treatment on a metallic white car will be hardly noticeable.
Of course wax/coating help prevent and hide swirling, effectiveness varies by product.
Hand wash is only as good as the method, single bucket-sponge water only wash is probably as bad as a traditional carwash.
Separate bucket for wheels. Car is washed in garage to prevent water spots. Dry with Makita leaf blower. No swirls since purchase. Re-polish and seal with Sonax Polymer Net Shield every 6 months.
Black car needs special care. It is a full time job!
