Machingers are my favourite gloves. I still haven't worn out my first pair and it's been over 3 years. I do wash them when they start to look a little dirty. I put some dish soap in my hands while I am wearing them and "wash" my hands/gloves. I hang them to dry. Machingers let you grip the sandwich to move it but have a nice weave that keeps your hands cool and not sweaty.
