I’ve been using “Pink Juice” since 1979! If you know anything about the photo industry, anything that’s been around that long has to be great! I certainly do which is why I use it to clean EVERYTHING except my sensor. Lots of folks use it as well, and some still head to the LensClens website wondering which of their product is “Pink Juice” as it’s known in the industry and then see the warning and wig out. Well, here’s the reason behind the warning as stated by the folks at LensClens.
“Pink Juice” is in fact the same item as Lens Clens #1. Because Lens Clens #1 has chemicals that will attack plastic over time (12-24 hours or longer) we have to protect our self from liability with a cautionary statement because we don’t know how every customer will use it. Our primary business is with industrial based customers, where usage can involve hundreds and thousands of parts. If you take a hard plastic part and soak it in a beaker full of Lens Clens #1 overnight or longer; it will start to pit or corrode the surface of the plastic part just like a beaker full of most cola’s (that ordinary people drink without hesitation) would do. You can use Lens Clens #1 for your camera gear just like Moose Peterson recommends, and either wipe it dry, or let it air dry and you will not experience any problems. When it comes to cleaning and maintaining camera equipment with “Pink Juice” no one has more knowledge or experience than Moose Peterson period.
Lens Clens #1 or “Pink Juice” can be used on any hard non porous surface. If the surface is porous like a soft vinyl fabric covering a chair it will soak into the soft material and remove some of the color so when in doubt use with caution. Hopefully this answers your question and concern. I fully support and endorse anything that Moose Peterson has to say about using “Pink Juice” to keep your camera gear clean, and in the best long term condition possible. Moose is the #1 expert and authority on cleaning and mainlining camera gear in my opinion. Best regards.
So moral of the story, don’t soak your lenses or camera bodies in “Pink Juice” or cola!
