#PIC5072: White Chalky Residue On Interior Trim Panels Or IP Dash Pad - keywords appearance chalk color dark dash dust film instrument leather left pad panel right spot spots stain substance vinyl white - (Jan 20, 2009)

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:

Some customers may comment of a chalky substance that is present on the interior trim panels. This is more commonly noticed on dark colored trim versus lighter colored trim. The release of this chalky substance is referred to as "Out Gassing" and can occur with plastic and vinyl materials.
Recommendation/Instructions:

DO NOT replace the trim panels to correct this concern. Clean the interior trim panels using Murphy's Oil Soap or an equivalent, non-acidic, cleaner. Replacing the trim panels does not guarantee this will not happen again.
Note: Murphy's Oil Soap can be purchased at most grocery stores. Follow the directions on the bottle for use.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.​

I've had a few people ask about this concern with their XLR.

Crimson Pearl told me about "Damprid" kit you can get at any Home Depot / Lowes. Since I started using this in my storage of cars...no white residue...
It works for me.

White chalky residue on door panels and dash.

My car was at the dealer today, and white residue was present on door panels and edge of dash.
It was easy to clean off with the Murphy oil, my question is it harmful?

It depends on what it is. If dust, no. If anthrax, yes. If you don't post anymore, your question will have answered itself.

Doesn't Murphy oil have a dark tint to it,almost a motor oil color? I would think theirs better car specific products that would do the job. Plus the materials on the dash and almost everywhere else are vinyl/plastic. Not leather wouldn't think their porous and residual oil everywhere.
