OK..so iv realized something recently and im a little lost for what to do.

i realized this morning that i need to clean my snakes tubs bleach them and what not..but i have the heating pads stuck to the bottom of the tubs! can i just remove the heading pads from the tubs and re-stick them..or will removing them wreck them? i thought i read someplace that pulling heating pads off once stuck on will wreck the pad?

any ideas are appreciated thank you!
