Did Optimum PC use to be called this? Can’t find it online...

No, not all but when I joined AG a guy overseas who used to post alot of details he did, nicknamed it that because it cleans "out of this world" and the name stuck with me

Is there any concentrate degreaser that doesn’t have citrus and that is safe on most surfaces interior/exterior? Zep citrus is cool but can’t be used on certain surfaces...I’ve looked at p&s enviro clean to start

3D has a couple that are not citrus based. But i plan to buy there orange de-greaser myself haha

btw you can get superclean at canadiantire has well.

The d-limonene from the citrus is finicky on certain surfaces. Was trying to stay away from that lol

The Zep product I mentioned earlier is not citrus-based and is safe.

Mean Green is not citrus

Hi folks, i haven't done much research on APC's. Is there downfalls to citrus based cleaners? I'm looking for an APC that i can use inside and outside the car.

I could get a gallon of superclean.....

Yes I am using the green apc from zep which is dilutable. I also own zep fast 505 which doesn’t seem to be dilutable. I’ve read that zep citrus isn’t really friendly on some surfaces. I feel the d101 from megs is the same as zep just being higher on the ph scale. Zep seems to be safer at 10-11ph.

The Zep ZDS 50 is some strong stuff. With a pH of greater than 13, I would dilute it at least 30:1 to get the pH to around 11.5. 40:1 brings it down to 11.3. The MSDS of D101 shows a pH of 13 which is slightly less in concentrate than the ZDS 50. A pH range of 6-8.5 is considered pH neutral. For delicate surfaces of interiors I use Simple Green diluted 10:1. With a pH value of 8, it is a safe pH neutral cleaner.

Interesting , if zep apc has a ph of 10.5-11.5 at full , I’m diluted 10:1 for interior/light cleaning. What would the ph be ? I presume around 8-9...I’m not sure how the calculation is made out

For a pH range of 10.5-11.5 I usually split it down the middle at 11 for the calculation. The formula is (original pH value - (-log (old volume/new volume))). In this case 11-(-log(1/11)) = 9.96.
That formula is used for a base or an alkali. For an acid it would be original pH value + (-log(original volume/new volume).
