6`ish years ago I fell into the detailing trap. I have a storage cabinet I bought just for detailing stuff. It`s packed full of Polish Angel, Gyeon, Letherique, Sonax and whatever other uber boutique brands. What I`ve learned, spending money doesn`t always mean the best products. And, brick and mortar doesn`t always = crap. The wheel cleaner everyone`s talking about is Eagle One Wheel & Tire. It`s like $5 for a 24oz bottle and appears to work 95% as good, if not exactly the same as the Sonax Fallout I bought for like $119 for 5 liters. I`m pretty bad at math but 6x5 is like 4 times cheaper. One of the most popular sealant`s right now is Meguiar`s Fast Finish. Which costs $15`ish, and works close to as well as the Polish Angel stuff I use which was 5x as expensive. Don`t get caught up on brands, and don`t listen to people who poo all over stuff you can buy at a Walmart. While Walmart`s full of junk, they have some stuff that`s great. With all the products I currently own, my next trip will be to AutoZone to get some Eagle 1 wheel cleaner. No more Sonax Fallout for me.
Turtle Wax Ice Seal n Shine for example, works better than some of the $40-70 a bottle stuff I have. I`d say go to Walmart or Autozone and pick up some Eagle 1 Tire & Wheel and the Turtle Wax. If you`re going to buy the Eagle 1, the bottle says something about Plasti-Dip & Black on it. They have 2 products that look almost identical, but aren`t. I`d use this on your wheels over a degreaser, but that`s just me. And at $5 a bottle it`s priced good even for a frugal person like yourself. If you want to be a bit more spendy, Mothers CMX is getting a lot of praise. It`s a SIO2/TIO2 spray sealant that`s $15-20 for a 24oz bottle. Saw some YT videos where it performed awesome in torture tests. One of my all time favorite soap`s is Meguiar`s Gold Class. $8 for half a gallon at Target or Walmart. And honestly it probably works as good as the Gyeon Bathe I use. Which cost like $25 for a liter. So uh, more math.... yeah it`s a lot lot lot cheaper to buy the Meg`s. Even if Bathe is better, it`s not 6x the price better.
To Echo what PA DETAILER said, detailing can be an expensive hobby, but you said yourself you`re a cheapskate. So you won`t fall into the same patterns I did of wanting to buy and try everything. I wish I could figure out how to be cheap, because I sure don`t have money for Polish Angel & Gyeon lol.
You said you had cans of degreaser, I personally wouldn`t use a degreaser that`s not diluted on wheels or tires. Perhaps someone here with more experience can chime in. I know at full strength you can do some damage with them very quickly.
