Bath yes, bowl of water no.
Gliders aren't going to use a bowl of water to bath in, you have to physically wash them yourself under a stream of running water that drains.
Turn both hot and cold water on and adjust it to where you can't really feel it being warm or cold when your put your wrist in the running water. like testing a baby bottle, you want the water close to your own body temp.
hold the glider kind of vertically slanted, keep the head and face away from the water, use one hand to let their back feet stand on and your other to support the back with your thumb under their front legs.
use a drop of dawn dish soap, the original blue kind.
Rinse really well.
Dry with a hand towel or tea towel, NO HAIRDRYERS. and make sure to keep the gliders warm until completely dry.
you may have to gently pick the wax off, and give more than one bath.
