Erm, I put my pads in a cup of super super hot boiling water, so put the kettle on and once its clicked to turn off, put it on again - with my kettle if I leave the lid off it keeps boiling... so the water is getting hotter and hotter. or, stick them in the oven but keep an eye on them!!! you don't want to cook them, you just want to melt the glue!
