Best option for express car wash & detail inside the loop?

Exactly what the title asks – I’m currently outside the third “loop” in Katy and I’ve got a membership to iShine Express Car Wash & Detail for $40/month of unlimited car washes, and I also love being able to use their vacuums for frequently cleaning out my car since I often do Uber on the side to generate extra income.

However, my living situation may be changing in the near future, and looking on Google Maps, iShine is unfortunately only located in the suburbs, outside either the 99 “loop” or west/south of the Beltway 8 loop.

One of the factors I’m considering for where I’d potentially be moving to would be a much shorter commute to the office on days I’ve got to go in, and it’s located near 610/I-10 going out towards Jacinto City, so I was considering areas like EaDo, Midtown, Downtown, Heights, that general area for inside the 610 loop and north/south of I-10 just east of the Beltway 8 loop.

Therefore, are there any good express car wash/detailing businesses inside the 610 loop or north/south of I-10 just outside the Beltway 8 loop? I’m familiar with Mister Car Wash, but I was wondering if there were any other businesses like them in those areas that I could look into.
