EcoConscious Mask Defog & Scrub, formulated with only the safest ingredients for our planet.

Friends, a foggy mask is the fastest way to miss the good stuff. Our Mask Prep Kit pairs two professional-strength formulas designed to do one job extremely well: keep you seeing clearly, dive after dive.

Mask Scrub handles the job nobody talks about: conditioning new lenses and reconditioning old ones so defog actually has something to grip onto. Use it on dive mask lenses and skirts, swim and safety goggles, ski goggles, and most sports masks.

Mask Prep Kit:

  • 0.5 fl oz Mask Defog
  • 0.5 fl oz Mask Scrub

Professional strength, built for advocates who actually use their gear.

    Usage

    Mask Scrub Directions: Apply to dry interior lens and skirt surface then rinse well. Repeat as needed and finally apply defog for crystal clear vision! Caution: Do not use on plastic or coated lenses. Avoid eye contact. Not for internal use.

    Mask Defog: Apply a small drop to the inside of a dry mask lens. Rub gently with a fingertip for 10-15 seconds, working it across the full lens surface. Rinse with fresh water before use. For best results, defog before every dive; reapply if fog returns mid-dive.

    So, I jumped into the lab and whipped up a batch using our tested and proven eco-safe ingredients. I like my defog a little more thick and believe the guar gum can also leave a slight film on the lens to help reduce fogging.  It worked great for me, so I started giving out samples to friends and Divemasters – they all loved it!

    Our ecosafe Mask Defog is based off of our shampoo that is tested to be biodegradable and safe for fish AND it works brilliantly!  Testimonials have been rolling in that it holds up to multiple dives, and our bottles are sustainably made from sugarcane resins and recycled plastics. Our mask defog is just another way to protect what we love and see clearly while doing so!

    Worked great!

    Much better than scrubbing with toothpaste. I can now put my mask on dry and see clearly without fog or streaks!

    L❤️VE it!

    I struggle with foggy masks. I hate scrubbing new masks with toothpaste and smelling mint for the days. The cheap soap solution found on most boats burns my nose and eyes. I bought a new mask on a dive trip and used both the Scub and Defog. My mask stayed clear! Toothpaste and baby shampoo will never touch my mask again.

    Clean Without Minty Residue

    I needed a mask cleaner, and was excited to see that S2S now offers one! Especially nice that it comes with the mask defog. It's a win-win. Clean mask without minty eyes and a mask defog that I already use!

    The Only Defog I Use!

    As a PADI Instructor, I need a product that stands up to multiple dives, provides my students a clear mask and is safe for the aquatic environment I love. Stream2Sea Mask Defog checks all the boxes!! Not only is it the only defog I use, it is a product I encourage all my students to purchase!

    The best defog!

    Everyone on the dive boat uses my Stream2Sea defog because it works better than all the other brands!
