I got it after I saw it recommended by somebody on this subreddit

Really detailing a car that's pretty dirty takes more than 30 minutes so dissolve yourself of that idea from the start. The main tool to get an interior clean will be a wet/dry shop vac (note that the ones that you put quarters in are never wet vacs and you risk shocking yourself silly if you use it that way as well as destroying the surprisingly expensive machine, don't do that). Get yourself a detailing brush (something like this, most auto parts places will have them) and put that in one hand and your vac hose in the other. Get at everything you can. Get as much of the chunks and dust as you can get to.

Work the carpet real good to get as much out of it as you can. There will be lots of sand and crap like that worked in to the fibers. Where you've got seams in the seats, spread them open and vacuum the crud out. Take the floor mats out and vacuum them separately. I usually hit the floor mats with a pressure washer. If you go to one of those self service car washes they usually have clamps on the wall to hang your mats while you blast them and that works really well. Floor mats see a lot of grime though and often times they'll be too far gone to bring back.

Next get a bucket with some hot water and something like Mr. Clean mixed in about 10:1. You'll want a microfiber rag and an old toothbrush. Go over all the hard surfaces paying extra attention to stuff that you touch a lot like the steering wheel, door handles and all the buttons and what not. Use the tooth brush to get into the corners and stuff. For buttons and switches, use the toothbrush mostly dry. Scrub a bit, wipe it clean with the rag and scrub more if needed. Do this where you have lots of light so you can really see what your doing. If you've got things like cup holders with grungy sticky goop in the bottom you can squeeze some soapy water into there, let it sit for a minute then suck it back out with the vac. Move the seats all the way up then all way the back when you're doing this so you can get into everything as much as possible.

If you've got leather, hit all that up with up with a leather cleaner followed by a conditioner. I really like Lexol products for this. They will leave your leather feeling wonderfully supple and smelling like new leather. Follow the instructions on the bottles. It goes apply cleaner per instructions, wipe clean with a damp rag then dry. Apply conditioner per instructions, let it soak in/dry then buff with a clean rag.

Hit all the hard plastic and soft vinyl surfaces with a cleaner/conditioner. I hate Armor All, it leaves everything shiny and greasy/sticky. Dust will be sucked to it like a magnet and it will look cheap and shitty in a few days. The Turtle Wax Ice products are a lot better IMO. It leaves a dry matte finish.

Finally you want to shampoo all the carpets and upholstery. Use the same mix 10:1 mix of water and cleaner, but get a fresh bucket of it. You'll want a stiff bristle scrub brush for this part. Slop a bunch of your soapy water on and scrub the bejesus out of it. Do a single area at a time, like one foot well. Suck as much of the water back out as you can with the vac. If you've got fabric seats, hit those up as well but don't get them so wet, they'll soak up a lot of water and make your butt wet for a while every time you get in the car if you go overboard. When you're all done with this, park the car in the sun with the windows open just a crack to bake the moisture out.

The last step is cleaning the windows real good. A good cleaner makes all the difference here. Stoner's Invisible Glass is the best I've found. If you've got a lot film on the glass, it can be helpful to start with straight isopropyl alcohol to cut through that. Use a paper towel for the initial grime. Finish with the glass cleaner and a lint free cotton towel (old dress shirts are great for this). Make sure you get all the way to the corners of the glass. Roll the windows down a couple inches and get the part at the top that's against the seal. I usually buff up all the shiny surfaces with this last step (gauge faces, radio display, mirrors, door handles, etc.).

Phew. So that's the interior. I'll leave the exterior for some one else (one tip though, Bar Keepers Friend and Magic Eraser sponges work wonders on wheels). Detailing is aptly named. It's all about paying attention the little stuff. To do a full interior on moderately neglected sedan sized car will probably take you about 4 hours. A pro can do it in half that. A minivan or SUV coated in child slime will be double that. If your fingers and back are sore the next day, you probably did it right.

Holy shit these are the exact ones I was looking for at on another detailing website but couldn't find them on Amazon. Thank you! I agree that I don't think I need that many options, so I might just pick up two of these but I'm not crazy about the metal band over the plastic band for possible scratch situations.

hmm. I bought a brush that was cheaper than the one listed in the wiki but it is definitely described as a detailing brush that wont dissolve. The bristles don't come out but simply lay down, like 90 degree angle lay down. I cant get good leverage to clean.
