Toucan Pool’Gom is not a sponge but, rather, a real eraser. So you have to use the Pool’Gom differently.
Moisten the tip of the Toucan Pool’Gom and rub it over the dirty surface.
Take great care. Do not use Toucan Pool’Gom on lacquered/varnished or vulnerable surfaces. You’re not sure? Then first test it on a small concealed area.
