Do not dump used oil or other waste fluids at the space. If the blacksmithing cause is currently accepting used oil, it may be donated appropriately. Alternatively, transfer your old oil to an empty oil bottle (we try to keep a few of these on hand), then leave it in the oil dumpster at a
participating Supercheap Auto location - they provide this service for free. Brisbane City Council also provides
guidelines for disposing of garage waste, along with free drop-off days for these fluids. If you need to dispose of a car battery, check Gumtree/Marketplace for lead recyclers who will often collect it for free (maybe even pay you!).
