How about megs APC+, i know its not a dedicated tire and wheel cleaner. but is it safe to be used for this purpose?
-APC+ has a pH value of 13.2...seemingly, then, a highly alkyline = "strong cleaner"...more than likely a good tire cleaner...may not be good for certain wheel-types, though...But, how you going to keep it off all the wheel surfaces while performing tire-cleaning?
-As has been mentioned/questioned before: Will, or does, this particular ph value tell the
whole story? Probably not.
I know the following doesn't begin to scratch the surface...
-Acid-Base titrations (strong acids/bases; weak acids/strong bases; weak acids/bases), buffers/buffering, salt and water formation through acid/base neutralization reaction processes---and, conversely, hydrolysis: salt reacting with water to form acids/bases...may be, or are, additions to the overall
ph story-line.
-The APC+ product description states it is completely water soluble, and can be diluted to the point of being a "safe" leather cleaner. Is this in fact true?
Here's a partial listing of it's MSDS:
1.a) Ethylene Glycol Monopropyl Ether
b) Sodium Metasilicate
2.a) Linear Primary Alcohol Ethoxylate
b) EDTA
When these two bases and two acids are:
'in solution'...Is this 'solution' then considered to be: Buffered; titrated through acid conjugation to the point of neutralization (ph7), or, beyond (13.2)?
-Not saying it's not ...But, if possible...What %, by volume, of water-dilution will it take to 'lower' this particular product's ph level to be "leather-safe"?
The Chemists/formulators really do know the products...It's usually up to the end-users to do the research to satisfy any curiosity they may have.
That, or trust in products' manufacturers, chemicals suppliers, the products' label-instructions, or members of detailing-forums, such as AGO's.
