I don’t know where to post this, but I thought this was the place even though I have no image.
I have a Black and Decker curling iron which I bought about 7 years ago. It is one of those butane lighter type iron. Now I haven’t used it in about 5 years, but I want to use it tonight!! Is it safe to use this? I don’t want it catching fire or something. There is still butane in the therma cell.
