Costco Members: Armor All Ultimate Car Care Kit Expired

That's a super loaded question. Could write a novel, but I'll stick to products offered in this kit (soap, window cleaner, interior protectant, tire shine, wash mitt).

Wash soap: you want a good pH neutral soap. Just straight soap, no wax additives. I personally use Meguiar's Gold Class (often abbreviated in detailing discussions as MGC). There are some other great ones but this one isnt super expensive and is readily available at most any store that sells detailing products.

Window cleaning: Stoners is what is usually recommended as a simple purchase in a store. It comes in an aerosol can and works great. Although I personally use a general APC (all purpose cleaner) diluted at around 64:1. Costs literally pennies to make a gallon of it and works just as well as any dedicated window cleaner.

Interior protectant: for dash, panels, etc. As someone already mentioned...Aerospace 303 (often referred to as just 303). Stuff is legendary. It's expensive but highly worth it. Try a 16oz bottle but it's cheaper by the oz to buy by the gallon.

Tire Shine: I personally use Optimum Opti-bond tire gel. Another item that seems expensive but it really isn't when you consider what you are paying for cost per oz. A gallon is about $50 on Amazon but you dilute it 1:1 so you're getting 2 gallons of tire shine for that price (19 cents per oz). But I think this current price is a high price probably due to inflation. The last time I bought it I only paid $34 for a gallon (13 cents per oz). When you consider at any auto parts store you'll pay $7 for a 20oz bottle (35 cents per oz) of another product that is inferior you start to see it really isn't as expensive as it seems. Just a larger cost up front.

There are other tire shines that are also great such as Carpro PERL or Chemical Guys VRP. These are the big 3 that get recommended the most in detailing circles. All three are water based as opposed to silicone that attracts dirt and grime whereas water doesnt. Most detailers prefer water based over silicone for a variety of reasons that I won't go into to prevent the novel I mentioned at the beginning.

Wash mitt: Get a quality microfiber wash mitt. Avoid cheap ones from Wally World. Just go for a decent quality one from Amazon. There's one by Chemical Guys that costs like $8. If you get really crazy there's a company by the name of "The Rag Company" that offer the best microfiber products you'll ever find. More costly but you get what you pay for. A good "cheap" microfiber towel is the Kirkland brand at Costco. They're usually like $17 for 36 towels. They are usually the bare minimum detailers will recommend for MF towels.

Please note - these are my personal recommendations based on what I tend to use. I also tried to mention other comparable products that are also highly regarded.

.97 means it's the clearance price already, so not likely to be lower in store.

FWIW most of the items in this kit are wipes, and the wipes always seem to dry out before I can use them all.
