Some soaps with lemon juice or other acidic ingreds will eat the molds but if you are using herbs, ect just oil the molds well before pouring in the soaps & then freeze them before you pop out the soaps to get them to unstick...I used to use antique candy molds that worked very well until I did a soap with lemon in them...lol.....learned my lesson...Michele'
