ok noted. how about APC for wheel? (just any apc) compared to degreaser i mean. I hope i don't get it wrong that degreaser & APC is similar just that degreaser is stronger??
the degreaser FX (going to get it soon from osren

) i planned to use on interior also, for the plastic/leather dashboard. then i'll get Fabric Cleaner specially for fabric seats, ie those once spray on, a little bit of product is likely to left inside even though wipe it with damp cloth.. so far actually has not done any serious detailing on interior yet, just read and watch many youtube how-to videos haha, like autogeek & wetshine and some others.

so a little advice from sifus is much appreciated
I'm not sure about other APCs and Degreasers, but here are what I picked up from Megs MSDS (as I'm used to using these two for quite a few years already):
Megs APCIngredients:
sodium C14- 16- olefin sulfonate
2- propoxyethanol
sodium metasilicate, anhydrou
water
pH: 13
Megs Super DegreaserIngredients:
oleylammonium chloride, ethoxylated
propylene glycol mono-n-propyl ether
potassium hydroxide
water
pH: 13.5
Megs Wheel BrightenerIngredients:
ammonium bifluoride
ethoxylated alcohol
citric acid
quaternary ammonium compounds
propylene glycol
ammonium fluoride
water
pH: 4.5 - 5.5
I'm no chemist so I don't have the faintest idea of what the above means. But here's my experience & observations based on a few years of using all three of them:
1. Megs APC - works best in cleaning 'organic' soiling, eg. dirt, mud, etc. which are insoluble in water. It's just an alkaline detergent solutions that contains loads of surfactants to 'loosen' and 'suspend' the solids so that they could be flushed from the surface to be cleaned.
2. Megs SD - works best in cleaning petroleum based soiling and able to emulsify oil, grease, etc. better than APC, but doesn't work as good as APC for organic soiling.
3. Megs WB - works best in cleaning brake dust. Since it's acidic and contains liquid ammonia - which is a good solvent for in-organic compounds, eg. metal. Still able to clean soiling and *some* oil/grease, but not as good as APC or SD.
Now, the above three are DEDICATED products to tackle SPECIFIC tasks hence, as I understand it, they are put under the Megs Detailers (pro) line of products. During the earlier times, I used to use those off-the-shelves 'wheel cleaners' from Soft99, Eagle F1, etc. There were times where some of them clean off the dirt very well but just couldn't get all the greasy film off. Then there are times where most of the brake dust were removed but still left the wheel a little dirty with soiling. Then I understood that being an 'all-in-one' there would need to be a compromise, *maybe* because it's not chemically possible (or not commercially viable) to have all three properties in one product. Being OCD, I researched and decided to get some dedicated products, and finally went for Megs D-line (not to mention being a cheapskate since it's cheaper in the long run...

). One gallon of those three can last me years (especially WB since I used that the least often) since it's dilutable (eg. 1 gal APC diluted at 1:10 makes 11 gals = 41.6L (!)).
Over the years, I've also tried some other products but, for some reason (maybe because I'm used to them) I kept coming back to using Megs. So far, considering their performance, I found that they give the most value for money (locally).
So is the degreaser a stronger version of an apc? I don't know about Osren Degreaser FX (I do have some of it & also their Multi-Clean) since I don't use them often enough, but I do think that Megs APC and SD are two different product and have different chemical compositions. I've tried using a *very* diluted (around 1:20) SD to clean some lightly soiled fabric and it doesn't work as good as diluted APC (at the same dilution). And looking back at the chemical ingredients, I'm not sure if SD is actually SAFE to use it on interior, especially for plastics/rubber.
My advice would be, if you're going on the 'professional range of products' route, better use it for what it's intended for. I've done a few 'trials and experiments' before, some went well and some didn't. And those 'didn't' some times comes and a costly price.....
Not a very reliable tests but can get an rough idea....UNCONTROLLED pH value test...
