Good buy, Honest mate, forget the add on bazooka solvent and all that it's not needed.
The best way by far to remove ground in chewing gum on a high commercial level is by firstly breaking it down then hitting it with a wire brush..... IMO
So steam away at it and then bazooka it, the bazooka allows you to gradually apply the wire brush to looses gum, saving you the hardship of getting down on all fours and scrubbing!!!...... yeah yeah it's just a drill in a tube and loads of people go on about it been a waste of money but in the right environment this cheap little tool can make you loads and save you time, especially if you charge per gum spot.......... which I don't I might add and still it paid for itself in the first couple of hours of use
