I know a lot of you use APC's cut 10:1 for interior cleaning. Mostly Megs' APC. I would like to know what the pH of it is cut 10:1, and how it compares to DP Total Interior Cleaner on carpets (not mats). Also, can Meg's APC be used on everything inside (except glass) like DP total interior cleaner?
 
Wow, the pH is 12.3. Now I need to figure out what it is for DP total interior cleaner.

what is it supposed to be?
 
Well when cleaning leather the pH of the cleaner should be 5-5.5. A cleaner with a high pH such as 12 will actually remove the tanning agents in the leather. This is why Im wondering what the pH of Megs APC is at 10:1 and DP TIC.

I wouldn't use Megs APC, nor APC+ on leather even cut 20:1. DP total interior cleaner cut 1:1 works the best for me. Use it full strengh for very dirty interior.
I do however use APC+ on interior (vinyl, carpets, fabrics, and mats) cut 10:1. But keep it away from leather.
 
Yeah, Ive been using DP TIC on everything and will continue to do so. I just bought a gallon of it, so Ill cut half of it 1:1. I never liked the idea of using APC on the interior.
 
I have seen woolite diluted 1:7 as recommended for leather. It has a pH in the desired range. It worked great on a grimey leather steering wheel. I had tried a interior detailer (these are alkaline types too - weak APC) initially and it seemed to "soften" it too much.

Woolite makes too many suds for me. Love it on carpet mats though.
 
From what I was able to find the PH of the APC at 10:1 would be 7.5. I'm not positive on this but it looks like the PH values of the water and the APC average out. This would make sense when you think about something like Lye having a PH of 14 and Vinegar (ph 2.8) being able to almost neutralize it. What information do you have on the leather cleaner ph being 5-5.5? I thought most leather cleaners where ph balanced. I should have paid more attention in those darn science class argggh.

Edit I just looked up my Megs Leather Cleaner Conditioner and it has a PH of 9 now I'm more confused

"A pH of 7 is neutral, 0 is the most acidic pH rating, 14 is the most basic (alkaline/caustic) pH rating. The pH scale is a logarithmic scale. Each unit of change equals a "power of ten". A pH of 3 is actually 10 times more acidic than a pH of 4. Conversely, a pH of 13 is actually 10 times more alkaline than a pH of 12. Therefore, a pH of 13 is 10,000 times more alkaline/caustic than a pH of 9."









thought this might help
 
I found this...I cannot explain it...describes a leather cleaner..maybe automotive leather is different but i sounds right. I read that Woolite diluted to 7 ot 10:1 is supposedly near neutral.

snip it....

Leather has an isoelectric point around a pH of 5.2 and in its completed state is typically below a pH of 4. Highly alkaline cleaners (pH over 9) work well for hard surfaces but not for leather. Continued use of high alkalinity will shift the pH higher and allows the lubricating fat-liquor components and dyes to migrate out of the leather. The leather therapy combination of the present invention gives cleaning and lubrication properties without introducing harsh pH changes.

The leather laundry solution is an emulsion that contains a unique combination of "anionic" (strongly negatively charged ions) and "nonionic" (neutral) fatty surfactants and fatty acid esters in a pH balanced (pH 6+/-) formula. The solution has a golden brown appearance with a pleasing odor.

The ideal pH range of the compositions is between 6 & 7. Variability due to water pH is insignificant since components are pH balanced at the manufacturing source and are stable across a wide pH and water hardness range

I currently use both DP Total Interior Cleaner diluted 1:1 and Megs APC diluted 10:1 and straight. I'll take them into work tomorrow and run PHs on them in our Chemistry Lab and post what I get.
 
That would be awesome, thanks.
 
OK just checked the PHs on Megs APC diluted 10:1 and DP Total Interior Cleaner diluted 1:1 and here are the results:

Megs APC 10:1 - 12.41 ph (very alkaline)

DP Total Interior Cleaner 1:1 - 7.65 ph (almost neutral)

These were checked on an Orion PH Meter. Hope this helps.
 
Wow then even DP is a bout 1000 times more basic than the recommended ph of 5.5.

Guess I should move onto another option huh?

Thanks wolf. Do you think DP mixed 1:1 made it more basic? Since distilled water is neutral, maybe DP straight is closer to 5- 5.5? Or it could be the other way around, Im just trying to think optimistically.

Id like do to more testing on specific leather cleaners. I have a feeling that the majority of leather cleaners arent 5- 5.5. Anyone care to help out?

Alright, just called Meguiars. The pH of their Gold Class Leather Cleaner & Conditioner is 7.

Im going to start a new thread for info on leather cleaners to see how much we can gather up.

D&D I'm wondering why you would need something more acidic (5-5.5 ph) than almost neutral to clean leather. We have Sulfuric Acid here at work and I know what it will do to a pair of leather boots. I know that the Sulfuric is way more acidic than a 5-5.5 ph but still I wonder why it would be beneficial to have something on the acidic side of the PH scale as opposed to around neutral, what benefit does it serve. I guess I wonder because some manufacturers PHs on leather cleaners are higher than 7.

Just posted the same thing on your Leather thread just posting here as well in case someone reads one and not the other.
