Removing the deposit even from the pans, at least from what: pour water, add soda -> put boil on a small fire. Now - attention! - add silicate glue (liquid glass), (it's Clay Contorsky - the former "for 14 kopecks") and all this (it turns into flakes) is slowly boiling in a small window for two hours (for skewers and cast-iron - up to four hours). Further, all the oil is oil, or it peels off, or a little bit to help it just with a strap, without any abrasives. Advantages - you do not have to do anything - everything itself is getting down + no smell, no other side effects - know yourself boils. Cleaned from the skewers to the lids, from pig iron to Al, removes even the film after the infusion of the cookie.
