How to hand wash - Fill a bowl with cold water, rinse and squeeze your used pads thoroughly before emptying the water and adding hand wash soap. Make sure there is no blood still coming out when you rinse before air drying them. How to machine wash - Save up all your used pads in a bag until the end of your period and then empty them all out into your washing machine, do a cold rinse cycle first and then add your usual laundry detergent (Do not use fabric softener!). Then just put the pads on a 40 degree wash and air dry them once they are done. We don't tend to recommend a tumble dry as it can reduce the life span of your pad but every now and then it should be fine! Then you are ready to go again next month…for the next 10 year or so! P.s Adding a tad bit of vanish if you have it, helps the process a little (Not a necessity though)
