Interesting blog site----but---DO NOT, I repeat, do not, use WD40 on your machine inner parts !! you can use
sewing machine oil itself. outside places are great to clean with NON-abrasive GoJO hand cleaner. be careful how close
you get to decals with any cleaner ! you can not easily replace them. I love the painted ones--purple being my favorite--
but it is a big job & best done by someone with experience in this field. I don't know if the "Glenn" mentioned on this
site is the same one, but Glenn Williams with the 301 site is honest, his guy is experienced with painting.
