I think most of you are missing out on Optimum Power Cleans true potential...

I very rarely see people say that they use OPC undiluted. Why? It could be a few things. First, and most obvious, it's much more cost effective diluting it. Second, I think people fear that using OPC undiluted is too "strong", therefore, being unsafe. Well, let me tell you, using OPC un-diluted is just as safe as using it 3:1. I think there's a mis-conception that using OPC un-diluted will dry out whatever you're using it on. I spoke with Dr. G, and he said that's NOT the case. If you're getting the desired results at 3:1, there would obviously be no need to change it. However, if you're ever struggling with something that's heavily soiled, DO NOT be afraid to use it un-diluted! Using it un-diluted, I've found it to be especially effective on heavily soiled leather. It cuts through grime like nobody's business! The whole point of this thread is to tell people not to be sacred to use it un-diluted, you'll be amazed at the results!

Only reason I don't always use it un diluted is cost. I've never felt it was unsafe but I do feel some people think it's unsafe. Hope that made sense.

have you tried it on coated leather?

...and optimum will be amazed with the higher sales volume.

OPC is the only cleaner that I have found so far that easily removes boot scuffs from interior plastic pieces around the sill plate in the door openings. OPC seems to leave some sort of white scummy looking residue that needs to be wiped off afterward.

Mark, does this white residue occur when you are using OPC and do you know what it is? I see it mainly when I use OPC in door jams or under the hood. It's no big deal as I typically go over these areas with either ONR or Poorboy's S&G as a last step to shine things up anyway, just wondering if you get that residue too.

Hey Mark,

When Optimum Power Clean first came out you gave it a try and found it to be an incredibly good and versatile product. I always read your posts and respect your opinion and decoded to give this product a try. I'm still amazed to this day how well Optimum Power Clean works. It's my go to product for nearly 90% of my general cleaning needs...

Thank you my friend!

The only time this product is half decent is undiluted. Its pretty weak IMO. Full strength is like Megs APC+ @ 10:1. So no, dont worry about using it full strength.

I will say that this a good product for greasy parts, like under the hood. Thats about it for me.

Interesting take. I've found APC+ to be weak.

I'm confused here. You state OPC is weak yet is good for greasy parts like under the hood? Talk about contradiction my friend. A great thing about OPC is that it's not a caustic cleaner.
