500 PSI DEFOG/MASK SCRUB PACK

I’ve used this product for years. It has always been great for new masks and for every dive. I never get a fogged mask when I use this product before each dive.

Works great

The defogger is the best I have ever used. Use just a small amount on each lens and spread it evenly. Rinse in water just before starting snorkeling. If you put too much amount, it doesn't rinse off. I used the scrub but it leaves residue. I had to use microfiber cloth to wipe it clean. Next time, I am buying just the defog and will use microfiber cloth for cleaning.

Used the mask scrub on a new mask and tested the defog after. The mask scrub did a good job of cleaning off the oily coating on the new mask and the defog worked like a charm. Even after flooding the mask 5 or more times the defog still did the job of keeping it crystal clear. I definitely would purchase a lager amount in the future.

I recently went on a dive trip and there were multiple people using different types of mask defoggers. This 500 PSI was the thickest of the bunch and also the last one used. It didn't seem to do the job as well as some of the other lighter spray defoggers. It was fine but I wouldn't purchase again. The scrub seemed to work well.

Good stuff. It's great that you can put the defog on when the mask is wet or dry as when I went snorkeling several days in a row on my recent cruise the mask wasn't always fully dry from the day before. I used the mask scrub before leaving home then the mask defog every day on three masks before snorkeling. There was plenty of product for four days of snorkeling but I'll need to repurchase or get a larger size before my next trip.

Used the defogger, used the mask scrub, used more defogger. Tried it dry, tried it wet. Tried leaving it on longer, tried rinsing quickly. Mask immediately fogged up every time as soon as I put it on again. Tried it on another mask, no difference. As far as I can tell, this stuff has zero effect. Was really surprised given the positive ratings

We used this and another brand and they both worked well to keep the moisture from accumulating inside the goggles in our snorkeling gear. Prep them the night before so you’ll be set. But don’t forget to bring it with you in case you need to reapply. Should last all day. It didn’t irritate our eyes.
