Clogged tear duct

I think my one week old has a clogged tear duct. He has nonstop eye boogers in his left eye that keeps crusting over. I go to the doctor on Tuesday to confirm if this is it.

Any advice on how to keep the eye boogers under control though until then? It’s like every second it happens and then if I don’t get it immediately it’ll crust over and get stuck on his eyelids
