Frog Spit Mask Defog

I have been using Frog Spit (the product!) for quite some time now. Since the product needs to be applied beforehand and dry before use, this has forced me to take great care of my equipment by rinsing it properly after use, and prepare it for the next dive every time. It also works on plastic lenses which suits me well given I use goggles for the pool (which I don't apply every time), and a Sphera mask for freediving. One defog takes care of all my needs. I suggest using the same after dive practice to avoid greasy fingers while applying. The product is like a soap also and helps in keeping the mask or goggles clean. It's perfect when used properly!

My husband is an instructor and I'm a divemaster. We used this on our last day of diving, and it's fantastic. We put it on before our first dive, and it lasted all day. Great stuff!

Worked all day. Never found any product but frog spit that works this well.

Yes the frog spit waa great we were new to snorkeling and plan to be scuba diving after certification we used it and our masks stayed clear. It was an awesome experience. Our masks were also purchased from silver forest and they dot ap well and felt great on our faces and the anorkles too. Thank you guys so much and hope to see ta again sometime soon

Even use it on my sunglasses

No need to apply on every dive. This lasts over multiple dives.
