Hello all. I am preparing for my art pipe install bying some tools etc penetrating oil.
The acetone tranny fluid mix.
This isnt my first rodeo as I have berks on my 350z and also at one point had art pipes. Once you remove the first time its a breeze. However on my Z the o2 sensors both of them chewed up the threads. Id like to avoid that this go around.

My question is
Is it safe to use the acetone tranny mix or even pb blaster on the o2 sensors or should that be avoided. If avoid it how do i remove the sensors without damaging the threads?
