Mandi from Vintage Revival is a fan of acid mirrors but not a huge fan of some of the DIY methods out there in the blogosphere. In her original post she explains how to go about giving mirrors an acid finish without completely removing the reflective coating completely, her preference. By leaving some of the reflective coating you create depth and color variation giving your mirror more character. One thing she emphasizes is to make sure you use your gloves and use them properly!
Here are the original mirrors that inspired Mandi.
