Trident Food Grade Liquid Silicone Lubricant and Conditioner
Use it to lubricate the o-rings in your SCUBA gear set-up and the zippers on your wetsuit and dive bags.
Add a few capfuls to the soak tub before putting in your suit, fins, mask and snorkel post-dive to help break down salt and other minerals from the water, as well as odor and stain-causing body oils. Spray on as a post-wash protectant and conditioner for rubber, neoprene, and silicone parts, to keep those materials soft and supple. Also prevents corrosion and rust on metal parts.
Food grade formulation means this silicone non-toxic and safe to use on mouthpieces as well.
