Haven’t tried but I wonder if a box of baking soda might help? If it can get rid of the funky odors in the refridgerator, maybe it might do the same in the forge?
Either one should help - just don’t forget and leave it in there when the laser is on. I recently tried the ‘laundry scent boosters in the vacuum’ and even after emptying the vacuum a few times it’s continued to put out laundry odor instead of dog hair odor during use - which means even those might work if you happen to have some already.
