That leads me to a more general comment, which maybe could not be
discussed here in detail. I think it may be important in the case of
such a streetcomplete quest that there are clear and objective criteria
for the use of the tags.

It would be necessary to have the information at least at
https://wiki.openstreetmap.org/wiki/Key:wheelchair#Amenities before it
is asked for amenities like car_wash to be completed by wheelchair=*.
Unless this is clear you only will be able to give a rough guess and add
a wheelchair:description:lang=*. This would already be quite fine if a
wheelchair user gets a precise information about the amenity by this
description tag. Even if there are somewhere clear definitions - the
final user has to know about them.

My personal opinion is that in this case - where a streetcomplete quest
asks you to fill in undefined tags, it would also be an adequate
procedure for someone who knows something about the subject to simply
add amenity=car_wash to the wiki page and suggest criteria, commenting
that these criteria are not based on a general consensus to reduce the
ambiguity of the tag.

At the moment there are 1024 amenitiy=car_wash tagged with some
wheelchair=* information. The criteria for the tagging are not clearly
defined. As far as I got it and made no mistake
nwr["amenity"="car_wash"][wheelchair][~"wheelchair:description.*"~".*"];
just gives two results worldwide. The description seems not to be used
too frequently.

Cheers,

Sebastian

[nearly completely off topic: I've never used a car wash but I know an
artist who made great photographs from inside the car during the washing
procedure - I always thought that it is usual to stay inside... at least
20 years ago... ;-) ]
