Hi Daniel,

I used this stuff , it doesn't smell as bad as Gunk, it's totally water soluble and environmentally safe (keeps the tree huggers happy!) wink
Joking apart, it's good stuff and I've used it for most de-greasing on my truck,including the gas tank.
I hope this helps

I've definately got this truck thing in my blood ... my DNA sequence has torque settings
