Using A foamer to clean wheels/tires

So I have been using Brake Buster because of its reputation of being a great wheel and tire cleaner in one without being super expensive. I believe it's a bit over 25 bucks a gallon on amazon. So I learned to realize when it is diluted in a regular spray bottle it does not really clean very well, like, at all. So I used it in a foamer, similar to the IK foamer only it's the Adam's polishes version. Its foams really well and clean great, my only complaint was that it uses a ton of product. So I wanted to try something different to get a similar performance but not use as much product so I tried using a chemical guys foaming spray bottle. It worked very well similar to the foamer but used a lot of product once again. So all of this being said, what does everyone else recommend to use to spray out their wheel/tire cleaner to get great performance but still save product. Maybe using A foamer is the best option, if so just say, just curious to know anything others have come across. Thanks.

I am using 4 to 1

Thank you very much for the info! I'll have to try that!
