My 18 year old daughter is very eco-conscious. This tip comes from her. After block fusing 4 yards of boucle, my iron was a gunky mess. I had no iron cleaner and I was preparing to drive 20 minutes to get some. My daughter suggested using canola oil to clean the iron once it cooled. I didn't really want to drive to JoAnn's so I tried it. It worked! I poured a little canola oil on a paper towel and wiped the soleplate of the iron with it. With just a little pressure and circular wiping, the iron was clean! I didn't have to inhale that noxious iron cleaner. I'm not sure if there is something magical about canola oil or if any oil would have done the job.
