I have lubricated my electric hair clipper with WD40 and although it penetrates perfectly, it continued to make noise because there is metal-on-metal friction at a high frequency and sufficient temperature. With pressoil, the noise almost disappeared, because pressoil is 100% for lubrication and does not contain many volatile hydrocarbons, like the penetrating WD40. I believe it also works for sewing machines.

Very good for lubricating scissors, pruners, etc. It would be good if it also came in a larger packaging and stated its uses.
