How funny … I threw one away this morning. :D

I use It’s a 10 spray-in products and always throw the caps away (unless I’m going to be traveling with them).

Afaik, it doesn’t affect spray products to not have the caps on, they’re just for possible leakage and such.

Well, lost my original response in trying to log in. I recycle plastic caps.

Lucille, most plastic caps are not airtight. Many have a tiny hole to allow the air to escape when you replace the cap. My personal opinion, with absolutely no scientific backing, is the caps are to prevent the product from being sprayed accidentally before it gets to the consumer.

Caps sometimes disappear. As long as I’m not traveling with it, or have young kids around, I don’t worry about it. In fact, one of my little travel spray bottles lost a cap. I put it in a ziplok to travel.

I like covers for sprayers - it protects the spray top and keeps it clean - also prevents accidental sprays.

I can usually find a replacement from my recycle bin

Tina Marie - holy cow, you're YOU again! 😊 Welcome back from HU land!

Lucille - I like the covers too. It would bother me to not have the original cap. I have issues. 😄 So, I would buy a new can and use the cover on that for the can currently in use. I would sleep better knowing my can had an OEM cover....because as I said, I have issues. 🤣

Ally De you are cracking me up! Yes it’s nice to get out of hu land! Thank you 😊

I threw the cap away. So far, the can, sitting on my bathroom counter, shows no evidence of having an unattended spraying spree ( a so far unexploited science fiction story) or overcome by layers of dust.

However, I do think caps are useful for travel. Also, for keeping the product safe from little fingers in the store, and the little finger owners themselves safe, as inexpert spraying knowledge might mean the child might spray himself in the face; and keep the store safe from the unwatchful parent who might sue the store for the capless product on their child's face depending on what the spray can contained.
