I would suggest setting aside some sort of budget as it gets pricey real quick depending on your level of interest.
For starting out I would suggest at least three 5 gallon pails with grit guards. One specifically for wheels and the other two for the “two bucket” method of washing. I use thick and soft microfiber towel as opposed to a sponge for doing the upper part of the vehicle and then a couple microfiber sponges for the lower part of the car that I throw away when they get soiled.
Use dedicated tools and sponges for the wheels and do not use those on the paint as they pick up small metallic particles from the brakes which can then scratch paint. Wheel woolies are also handy to have to clean the wheel barrels and inside of fenders.
Depending on contaminants left on the paint after washing, an iron or tar remover might be required. I bought Trix which does both iron and tar. Haven’t used it yet but reviews seem good. After that, a clay bar may be needed for other contaminants embedded in the paint. You can either clay using a clay lubricant compound or I like to use car soap in a spray bottle so I can rinse it off when done.
Once the outside of the car is clean, clean the door jams and then try the car completely. If applying a wax/sealant/ceramic, I wet a microfiber towel and then dry it without a drying aid so the paint is ready to accept whatever coating is being used. For a regular wash on a vehicle that is protected, use a drying aid to reduce the risk of scratching.
As for products, there are a ton out there. Search YouTube and figure out what fits your budget and work from there. I’m a huge fan of Ammo NYC products. They are all proprietary blends and Larry has a video explaining how they all work and how to apply them. Can’t go wrong with any of his stuff. It’s all east to use and the outcome is always great.
Depending on condition of your paint, paint correction is another realm of detailing to consider. If your paint has scratches/swirls, you may want to consider having it corrected before applying any sort of ceramic or sealant for the best possible shine and outcome.
Detailing is one of those things where you can really go deep down the rabbit hole. Like I said in the beginning, figure out your budget and level of commitment and work from there. Having flawless (or as close to perfect as you can get) can get really time consuming and expensive. Between tools and materials I’ve spent close to $1500 in the last couple of years for an electric pressure washer, towels, products, paint correction tools, etc. I find it relaxing to spend time in the garage listening to music and having a clean car. Winter is almost over here and it’ll be time to paint correct the Stinger and
Telluride and I can’t wait.
Good luck.
