Wash off dirt and grime, especially on the threads.
Do not allow salt to accumulate on the threads. Use a dry bag over your BearVault in saltwater conditions.
Use mild soap and warm water.
Use a clean toothbrush (or similar) to clean the threads of both the canister and the lid.
You can put a BearVault® canister in a dishwasher, using mild detergent. The lid should be hand-cleaned.
Keep your BearVault® strong
Keep DEET and other harsh chemicals far away from your BearVault®. Double-bag these in ziplocks, and be very careful not to leave residue on the outside or opening of the bags.
Some fishing lure liquids can cause chemical damage to the plastic.
Chemical damage can result in spontaneous stress-cracking of the canister, rendering it weak and unusable for food protection. If chemically damaged, the canister should be discarded (it cannot even be recycled with chemical damage!).
Milky blotches or lines on the canister, sometimes accompanied by spontaneous cracking, indicate chemical damage.
UV light also damages plastics over time. Store your BearVault® in a cool dry place, out of the sun when not in use. Try to keep your BearVault® in the shade and do not store it long-term in the sun. Signs of UV damage include a yellow tone to the blue canister. UV damaged canisters are not usable.
Close the lid properly: swivel both nubs past the stopper, but do not over-tighten it.
Lid action can be improved by applying a little food-grade silicon lubricant on the threads once a year.
