carb cleaner - has it ever worked for you?

has anyone cleared obstructing dirt from his carb using just carb cleaner without having to dismantle carb?

what happens to the dirt? ever made it worse with carb cleaner?

ive got a pierburg 2e3 on my golf which is giving bad idleing.i think it might have sucked up some crap from the bottom of the gas tank. i have an inline filter and changed it.

what sort of dirt can get past the inline filter?

thanks,
