Forget the love to all bullshit.....

If you want to make sterile oil,then you are going to need to have some tools of the trade.
You'll need to get some BA {benzyl Alcohol} and some Whatman filter's {or the likes of}
You'll need to go down to the local shop,grab your favorite oil {not coldpress hippie crap}
Proper heat and chemically extracted cheap shit,like rice bran oil {healthy and very viscous}
Now take the amount you need to reduce your gear,wack it in the microwave 'till it is starting to boil,
Then let it cool down. Add 2-3% BA and filter it with your whatman filter,add it to your gear and give it a hot bath {swirl it in a hot pot of water,to further mix it}
