Dross stays on the table instead of the floor. I picked up a $28 needle scaler from Harbor freight and it works great. It leaves small marks on the metal but since it's the back of the part it's not an issue. They easily sand away if you want. Just be sure to clean the oil off the scalers before using. Don't dread the dross!! If you like this tip, please click the Fab Forum like button below Apologies for the vertical video. Had to one hand it.
