Love can fix everything, not in this case... in this case you need a little propane flame thrower

No , i'm not kidding...
my brake pads got a bit of oil (mineral oil) and i found a little trick to fix them.
Maybe is not the same process to fix every pads but in my case seems working as well.
I removed the pads and i left them on the floor , my idea was to remove the oil without using any chemical reaction (i need to find a way to do it too).
so i figured "let's try to vaporize the oil"? those pads seems in very badly condition (can't brake with the regular power and they also made a frustating noise)...
So here what i come up with... a propane torch!
Set them under the fire for some minutes , let them to come back to the normal temperature and after a bit of cleaning i mounted again on my mtb.
Well seems this way works!
Sadly the results was not grat with the front pads , in the other case they totally remains as before.
What you guys think?
do you have some personal way to fix them?
Sorry for my bad eng.
(My pads and brake are Shimano deore M446.)
