Petroleum jelly spray, reef safe?

[Swip]

I use a wooden mold for cement frag plugs and put petroleum jelly on it to keep the cement from sticking to the wood.
Right now I use normal petroleum jelly. Is there anything wrong with using the spray kind?
It would be much easier for me.

Can you provide the name or a link to the exact product you're considering?

Yes the name is Presto Vasline Spray, here is the safety sheet but it's german so it's probably not helping much. http://www.atu.de/extern/files/artikel/PRE021_Sicherheitsdatenblatt.pdf

I would suggest using vegetable oil spray like the kind used for cooking, assuming it's sufficient to keep the cement from sticking to the wood.

The vegetable oil spray does sound safer for the tank. I don't read enough German to decipher that data sheet, unfortunately.

Vegetable oil spray seems to have the same blowing agent(pentane) as the petroleum jelly spray. At least the ones I've seen here in germany. They seem to be considered food safe(both the vegetable oil and the petroleum jelly spray), but the safety sheet of pentane says it's damaging to water organisms.
Is this true or can I still safely use the vegetable oil spray?
I've also thought about putting wax on the wood, would that be safer?

Thanks, as always, for the help! Really love the chemistry forum

The pentane likely would be toxic if enough of it were present, but the spray shouldn't have much and the pentane probably won't remain on the surface very long at room temperatures.

Would just a light coating of liquid 100% natural vegetable oil work as the release agent?

Edit: Ha, never mind just read the data safety sheet.

How about a 100% silicone spray like what's used for treadmill belts? We use 100% silicone O ring lube for unions and my understanding is that is reef safe.

It'll have a propellant of some kind, too, so you might want to check that.

I think they come in pump spray bottles.

Can't you just soak the plugs in some white vinegar for a while to remove what ever impurities are on them?

 

[bertoni]

Pump spray bottles should be okay.

Vinegar might help remove impurities. That depends on what's in the plugs.
