I'd like to get your opinions on using an APC to clean interiors. Vinyl, leather, plastic, upholstery, carpets, rubber, basically everything except the glass. Is it possible to use different dilutions of an APC to clean everything? I've read a bunch of threads that have differing advice. Some say it's fine on most surfaces, some say APC has no place in the interior.
I'm thinking 1:5 for dirty carpets and mats, 1:10 for plastic and rubber, 1:20 for leather and light maintenance everywhere.
I'm looking to maintain a 2013 BMW that I just bought (not too dirty) and deep clean then maintain the family van (kids are pigs).
Thoughts?

You're definitely asking the right questions.
I think having a dedicated carpet cleaner, dedicated leather cleaner, dedicated leather conditioner, and dedicated plastic and rubber cleaner is completely overkill. But, I am a professional so my opinion is bias.
Personally, I would get Mckee's 37 Hi-Intensity APC+ because it's incredibly versatile. Also, (like Eldorado2k already mentioned) I think you could just keep it simple by only having one dilution of whichever product you decide to purchase. At the 10:1 dilution M37 Hi-Intensity APC+ is extremely effective at cleaning dirty floor mats while also being safe enough to use on leather.
One thing I would recommend is getting a product like M37 Fast Interior Detailer to use after cleaning with the APC to neutralize the alkalinity of the APC. Or, if you want to save money you could just use your rinseless wash product. Before buying Fast Interior detailer I had used ONR, D114, and Wolfgang Uber to wipe down leather after cleaning with an APC.
The one exception to the 10:1 dilution ratio I recommend for M37 High Intensity APC+ is for carpet & upholstery cleaning. These areas can't be as effectively neutralized and if you're not using an extractor (I never do) then you might want to err on the side of caution and have another bottle of APC+ diluted 20:1 or have a dedicated carpet & upholstery shampoo.
If you don't mind spending your money on the best quality interior cleaner, Ultima Interior shampoo gel is a seriously amazing interior cleaner.
One thing to keep in mind (like other members have said) if you are consistently keeping the interiors of your vehicles clean then there is really no reason to ever reach for an APC. You can just use your rinseless wash and a microfiber towel or use a dedicated interior detailer. That way you never have to worry about letting cleaners dry in the carpet or leaving a surface in an alkaline state.
