What`s the best way to remove old wax in the roofline gutters? Have some old and caked on wax in the gutters that even a tooth brush can`t reach that well. Just wondering what you guys like to use to strip/wipe wax in crevices. Thanks.

I get a thin card like a credit card or something like that and drape a MF towel over it and stick it in the crevice. I actually use a old access card to my local gym
