I have tried so hard to make these homemade foam soap pumps work. Mostly because I love mason jars, especially when they have pretty soaps and lotions in them to use as well. I have tried many, many ways to get them not to rust. From cutting the hole differently, to using a paint coatings that is supposed to prevent rusting, to hot glue gunning or caulking around the hole where it meets the pump. None of them worked for me.
Until I discovered the plastic lids. These may have been out for awhile, but I'm a little slow. Months ago I bought wide mouth and regular ones, cut that hole, inserted the pump and have been washing our hands with no rust ever since.
Hallelujah! I love these. So easy and they were really cheap. Bonus!
