oh shooot!!! I read this wrong. I'm sorry. Though I'm not wrong about injecting PEG. Which I will show after I point out my mistake.
From Australian health on poisons. It says to
WASH with PEG if you get Schedule 4 poison on your skin.
S4 If on skin, immediately remove any contaminated clothing, wash
skin with methylated spirit or PEG (polyethylene glycol) 300 or 400 if available, then flush under running water until advised to stop by a Poisons Information Centre (e.g. phone Australia 131 126; New Zealand 0800 764 766) or a doctor.

Which I know from experience to remove a thick petroleum product such as tar from your skin you use a thinner petroleum oil. Though injecting PEG is where your Mfsd2a genes will take the oil to where it does not belong.
