"Strip wash" is basically a non ph neutral car shampoo that is stronger than the ph neutral wash that most detailing companies offer. It has the ability to remove previously applied waxes/sealants etc. This is what you want to use before doing a complete detail. adams has theirs but i use this:

Of course after any application of wax/sealant/ceramic you want to use a ph neutral soap.
Then iron decontamination- watch the video for instructions but it's easy to use

clay bar- Really any clay bar will do. You can buy many at auto parts stores then you just need detail spray for lubrication. I just use the large bottle of meguiars detail spray. No need to use top dollar detail spray for clay lube. I do however also like Adams clay mitt- pricey but it makes the process go a little quicker.
Now on to polishing the car . . . There's a whole world's worth of info/opinions/ equipment options out there. You could research it for months and never have a clear answer. I'll leave you with this video as i think it boils it down for a beginner. Harbor freight DA machine, griots complete compound(not what i use but it will do well).

Then for maintenance use Adams Ceramic Boost every 3rd wash to prolong the longevity of the coating.
Welcome to the big world of detailing! haha. I'm sure you'll have more questions throughout the process. Don't hesitate to ask
