APC alkaline free?

[F-150]

I was wondering if this product is alkaline free or ph balanced. I notice that on my bottle of GC leather aloe cleaner, it says that it won't strip the leather's vital oils that harsh chemical cleaners do. And I like using apc for leather cuz it cleans very quickly and is a spray. And I found out that leather cleaners that are non alkaline will prolong the life of the leather. But I don't want to use APC on leather if it'll actually have a negative in the long run. From what I know, it's a Meguiar's product so it should be perfectly safe for it's intended use, I'm just making sure.

Any time you use APC on leather or vinyl you will want to follow it up with either a leather and/or vinyl protectant.

Yeah I use Lexol conditioner. I've found that I like the look and feel of the leather more after using that than any other leather conditioner product out.

But is APC non alkaline?

According to the MSDS the pH value of APC undilluted is 12.3, so I guess that's a no...

Btw, you can find the MSDS's here: http://meguiars.com/msds/

I think it's safe to use APC regularly for cleaning leather, if dilluted accordingly.

APC pH = 12,3
water pH = 7,0 = neutral

APC 1:10 pH = 7,48

so if APC is diluted properly 1:10 the pH is nearly balanced.

Hope it helps

Eh? How did you calculate that?

I use a different APC which undiluted is at pH 13.4, when diluted 1:50 the pH value is 10.6.

The pH value of Meg's APC dilluted 1:10 is definitely NOT 7.48! Remeber the pH scale is logarithmic, so calculating the resulting pH after dilution is not so simple!

My guess would be that Meg's APC diluted 1:10 would be at about pH 11.

It would be great if someone could comment on this. Maybe Mike knows the answer?

You mean 10:1. And thanls for the msds, I forgot about that.

Sorry for my wrong answer, you are definitely right, the pH scale is logarithmic and the answer is not so simple.

The pH of dilutions depends on many complicated factors: chemical reaction, electrolytic dissociation, temperature, and so on.

Because we don't know the exact chemical composition of APC, we can only determine the pH value of the dilution relative exactly with indicator paper.

For acids it gives a rough calculation for dilutions acid:water at 1:10 increase the pH approximately about 1 so it could be analog that dilutions base:water at 1:10 decrease the pH about 1.

Would be good, if a chemist from Meguiars could give a better answer - it interested me also.

Well this is some info I got from autogeek (the website) about Meguiar's APC.
The alkaline cleaner and wetting agents produce a superior foaming action that is strong enough to lift dirt and grime out of floor mats, but gentle enough to safely clean leather.

Don't worry Just wouldn't want anyone to think that APC is almost pH-neutral when diluted.

Yes, it's worth respecting that a base with a pH value of 11, will be ten times stronger than one with a pH value of 10!

I've read that water that has been in contact with the air for a period of time, is no longer at pH 7, it's then about 5.7. That is why it seems to lower the pH value of a base a bit more than 1 when diluting it 10 times.

Btw F-150, where did you find out that non alkaline leather cleaners will prolong the life of the leather? Might be safer to use something like GC rich leather cleaner then, if used often...

[F-150]

I got some of this info on the Lexol site. Under their leather cleaner. But also somewhere else like properautocare or something, I forget, I'm still searching.
Someone could always get a handheld ph tester if they want to test diluted apc. Also if they want to drop around $70. But yeah the GC leather cleaner cleans well, it's just harder to use. I like a spray leather cleaner and haven't tried the lexol leather cleaner because I've heard it doesn't clean very well.

I have another question, from seeing what other sites are saying I'm getting confused. For interiors, like door panels, or leather, or carpets. Is APC a spray agitate and wipe/dry product? Or is it a spray agitate rinse(for instance go over with a damp terry cloth) then dry?

Re: APC alkaline free?

Aloe Leather Cleaner, Aloe Leather Conditioner and Quick Interior Detailer are also alkaline.

Re: APC alkaline free?

wipe/dry or rinse?

I also noticed this difference in automotive interior cleaners.

Some products like ArmorAll oxy ....(I do not remember the name precisely) cleaner requires rinsing after cleaning vinyl. I do not want to rinse my vinyl door panel. So I chose products that can be (according to the bottle label instruction) merely wiped off.
