Question by dankmaster24: How can I clean unknown automotive residue off a pyrex cassarole dish?
I inherited a very large pyrex cassarole dish that was used to hold some sort of dirty automotive oil (possibly motor oil, but not sure). It is now covered in a thick, stick, oily residue. Is there a way to chemically clean this so it is safe to use for cooking, or is this a lost cause?

Neat dish soap is a natural decreasing agent
Soak it in this and hot water over night
Give it a quick wash then put it in the dishwasher
If you don’t have one wash several times in hot soapy water
