Must be awesome to get a new car! A clean and near perfect sheet, must be great to have. Ron's advise is most trusthworthy here, but I'd like to give my take on things as well.
I suggest you get the following:
- ONR Wash&Shine (Blue one), I think it's the more versatile cleaner, since it's more adept to interior cleaning. Blue ONR seems to have a lot of gloss enhancers these days and pretty okay protection, which is awesome. I find it hard to get streak free windows with ONR, but maybe a stronger concentration in a spray bottle would be an awesome window cleaner. Need to test that out. Don't expect it to work on kicked up sand, mud or bigger bits of debree, these should preferably be rinsed off first.
- Opti-Seal is awesome as a drying aid, and very economical. Watch out though, cause it will likely ruin your dring towels, at one point they will only work properly if you use Opti-Seal. That's the case with me at least. Opti-Seal gives a nice shine, but nothing crazy. It's the best glass cleaner I have used to date, but not perfect and my search continues. The ease of use with Opti-Seal, whatever way you apply it is absolutely insane. Expect Opti-Seal to last 3 months if used as a drying aid. You won't really know when it's gone, so just apply it a couple of times a year as a drying aid (or during every wash, for easy drying), or two times a year with the foam applicator. I personally don't use it on wheels.
- Optimum Car Wax gives an amazing shine, but requires a bit of elbow grease, compared to Opti-Seal, and is a bit more finnicky. As a drying aid it works good. I would expect it to last a month or three weeks when used as a drying aid or when used dry.
- Optimum Power Clean is an absolute necessity in my opinion. If only to clean wheels and tires, on which it works awesome. For tires I would suggest a stiff brush from the rag company, and for wheels the Optimum Wheel & Body brush. Maybe a lug nut brush. I don't know yet how to clean wheel barrels or wheel wells if you want to stay rinseless. But a Worx Hyrdoshot may work great for the whole wheel area. I also use Power Clean to soak bugs on the frontal area (front bumper, hood, grille, windshiels, wing mirrors), and use distilled vinegar to neutralize. Be careful though, since vinegar causes surface rusting on bare metal. I first clean the frontal area quickly so the dirt is off there, allly OPC, agitate with W&B brush (SOOOOOO SOFT), spray vinegar, wash again and dry. Works pretty great.
- Avoid using Super Clean or any of those cheaper All Purpose Cleaners. They ruin your car, your equipment and possibly your health.
- Clay as needed indeed, and I suggest reapplying Opti-Seal (And Car Wax) after claying. A good test would be to get a plastic bag, put your hand in it, and gently wipe the paint after you cleaned it. You will feel if it needs claying.
- Towels are a great way to use ONR, but the Big Red Sponge or the new Ultra Black Sponge are also great ways of applying ONR to the car. They need an occassional scrub with Power Clean, but generally, after a dunk in ONR, they are completely clean. When used in conjunction with a large and high qualtiy drying towel, there isn't a faster way to wash your car, which you may find enjoyable.
- Optimum tire bond has not served me very well yet, and seems to last for a short amount of time sometimes. But this may be due to improper cleaning beforehand on my part.
Hope this helps.
