Here is a link to a product description of the Varsol product.
It appears to be a cleaning type solvent or "Stoddard Solvent". I had not heard of it before. http://www.exxon.com/exxon_lubes/tig...ets/pds086.htm
There appears to be at least two types of Naptha, a light and a heavy. I don't know what type we use. I'm going to check with my supplier on it.
The Naptha type I have used, I have passed a torch over wet metal to dry it faster, and it would not burn when the torch was removed.
I'll have to toss some matches in the parts washer to see if it burns!
The Varsol 1, or Varsol 18, looks good. But just like the Naptha, there are other products like Varsol 1 with Naptha, and a long list of other Varsol combinations.
Spiking the solvent with other products will most likely increase the flammability.
Keep the parts washer covered and in an area where there is no other flamable products for safety. Also away from grinding, cutting, equipment. Sparks can fly a long way!
I bought a proper parts washer with a melt away lug on the lid. It will drop the lid if the parts washer catches fire and the lid is up.
We did have a fire a long time ago (1949) when they used gasoline, (yes gasoline) to clean a tractor, a drop light fell into the bucket and POOF! They never did that again!
Wear hand protection, these products can cause nerve damage, lung damage, skin cancer, and dermatitis.
