I use a product that is not quite straight d-Limonene. It has some others stuff mixed it to make it more useful as a cleaner, and an emulsifier.
I don’t use it much, but it does come in very handy when you need it.
I mostly use it on carpets for oil and grease stains at ratio around 3-4oz per gallon. I use it straight on a cloth for gum, and adhesive removal.
From my experience it doesn’t make the best all around APC because:
It’s expensive.
It doesn’t foam
It’s not safe on more delicate interior plastics and “leather” seats.
Not really good wheel or tire cleaner. Maybe better at stronger ratios.
Ok as a tar remover straight, but not as good as something like Tarminator, and more cost because you are using it straight.
Then you have APCs with a little bit mixed in.
I my opinion APCs with added orange terpenes do seem to clean better than most APCs without them.
I also avoid using them on interiors to some extent and only use it on “leather” in extreme circumstances. I don’t use it on possible delicate or clear plastic pieces. I will use it on hard interior plastics in places like kick plates around the doors and the bottom of the door cards where they get scuffed a lot.
I use this type for most exterior needs. Mostly wheels and tires, but also for cleaning plastic rubber trim. Something as as pretreat on the paint occasionally, always work from the bottom up. Avoid it on glass and I try to avoid getting stronger cleaners on headlights too.
I believe they can only add a small amount of “orange” because it decreases the foaming affect.
I have used, and now use something similar to this
