Is this stuff safe on rubber such as hoses and door gaskets? The manufacturer claims it is but I have noticed it contains petroleum distillates.

Not answering your question directly, but I bought Gunk Silicone spray and it has a boatload of petroleum in it. Stinks like penetrating oil. Chances are the Liquid Wrench is just as bad.

The Liquid Wrench smells the same way.

Use Ace Hardware Pure Silicone lubricant (spray) - really good stuff - no petro, no odor.

Dielectric Grease is great to use on rubber gaskets and hoses. It is a little messy but conditions them great.

Some silicons are not compatible with rubber and will actually deteriorate it. Without knowing the exact composition and a compatibility chart it is difficult to know which ones are bad.

Spray the silicone spray on a styrofoam coffee cup. If the cup dissolves quickly, this is not something that is safe around plastics or rubber. For long term safety around rubber, use a pure silicone spray or the grease as mentioned above. You would be surprised at the number of silicone sprays that will fail the cup test!
