PARTS ARE BAKED TO GAS OUT ANY REMAINING OIL
'Gas-out' occurs by baking the parts in a specialty oven at a consistent desired temperature. For most metals, this is done for around one hour. Plastic parts are baked separately at a lower temperature and for various time lengths, depending on the product.
COOL DOWN & FINAL INSPECTION FOR ANY OIL
Once done, the parts are removed to cool and are inspected to see if any oil or other contaminants still remain. If there are oils still present, the soaking and baking process must be repeated as many times as necessary to completely clean the item. This could take several hours or several days.
