My eyeglass cleaner is not spraying anymore. I tried washing the sprayer with hot water and it still doesn't work. What do I do?

Take it back to where you bought it, I buy mine at Walmart, and have had to do this several times.

Buy a new one, and use the it, then pour the current into that bottle as it gets used up.

Just pour (dampen) a cloth with the fluid, and wipe the lens, then wipe with dry.

Buy a new one, they're not that expensive, or buy a spray pump at your local dollar store, pour the contents in, and use that. It's the contents, not the pump that are important, so transferring the contents into a different (never used or cleaned thoroughly) container with a pump, is a good solution if the pump clogs.

I agree... they are cheap. Throw it out, or better keep it to refill the new one you buy when its used up.

Mix your own with distilled water and a small amount of ammonia and 100 proof vodka or pure isopropyl rubbing alcohol. I mix 50% distilled water. 49% alcohol like either isopropyl alcohol or ethyl alcohol like vodka (best) and a tablespoon of pure ammonia liquid. That's about what Windex is made of. Some rubbing alcohol is denatured and leaves a bitter residue on your fingers and your glasses. You do not want that, so use ethyl or isopropyl alcohol for an alcohol that leaves no residue.

I had glasses for over 2 decades, before I got lasik. Not once did I use eyeglass cleaner. A bit of liquid soap, some warm water, rub it, then dry, and it's fine.

Vodka, distilled water, ammonia, and isopropyl alcohol? That sounds really expensive. Soap and water is cheaper. Heck, just buying a new eyeglass cleaner at Walmart is cheaper.
