no you cant clean it, and dont try lol the ants wont apprciate it! as Steve said, if you are worried, add another test tube so they can move if they need to
if you connect the two test tubes to one another, remeber they need to breath, so leave a 1mm gap between the two test tubes when u stick them together with for eg selotape, then put some tiny holes in the selotape for air
