When it comes to bending hard tubing, I've tried to watch videos, as well as read forums, and I keep hearing/reading about using olive oil to lubricate the bending insert so that you can easily pull it out of the tube after you're done with a piece. Well, I have been test bending some pieces and using olive oil with the bending insert, and while it's been fantastic for keeping the insert from getting stuck, I just can't seem to completely clean the oil out of the tube properly.
After several rinses/washes with warm soapy water (even using the insert to assist with "scrubbing"), there is still a lot oil on the inside the tube, and I'm wondering... Is there is another lubricant that I should be using instead, or is there an easier way to clean this olive oil out of the tubing itself?
I am likely going to have a few pieces that are longer and have some slightly intricate bends, as well as using white tubing for the final build which is not see-through; whereas, the tubing I am doing my test bends with at the moment is see-through and I can easily notice that I still have oil to be removed from the inside of the tube. Unless, of course, olive oil doesn't adversely affect water temperature and water-cooling hardware?
Any help is appreciated, thanks.
