So 1st world problems. I now have a couple bottles of the Lysol Disinfecting Spray (the metal aerosol spray cans, not the plastic spray spritzer bottles).

I was never a user of the Lysol aerosol (disinfectants) prior to The Year of COVID. But here we are. So I've read the Directions for Use. And it says nothing about shaking the can before use. Is this odd? Or is it intentional that I'm not supposed to shake the (disinfectant) aerosol can prior to use?

I have used other aerosol cans for other uses, like an aerosol can of spray paint, for painting hobby models and priming wargaming miniatures, etc. Those cans do tell me to gently shake the aerosol paint can prior to spraying.

I have Googled this, and found no definitive answer. Maybe Google isn't a know-it-all after all.
 
OK, I have like 6/7 cans of Lysol in my house, don’t ask me why.😁

Now, to your question

I went into my laundry room, and I looked at the Lysol cans, and the directions explicitly state to:

“Hold up right, spray 6” to 8” Away from surface, Spray 2 to 3 seconds to cover surface, allow for 30 seconds to disinfect.”

******************

Yet, ‘Oust’ provides the same directions, but explicitly underlines/bolds to “Shake well before use.” However, Oust is also an air sanitizer in addition, not just a surface sanitizer, so that might be a reason why.

But what I do, I simply shake the can by default. It doesn’t seem that it’s made a difference one way or the other for Lysol, I’d say that’s just ‘force of habit’ .

I twirl the cans in my hands to get everything combined about 20-30 times. Shaking seems to create a more foamy spray in my experience. Ideally, you'll want a very fine mist on whatever you're disinfecting and leave it like that until it air dries.

After you posted about Oust, I ran into a "newer"Lysol product called Lysol Neutra Air, which happens to be an "air sanitizer" (just like Oust). So I read the online instructions on usage... and sure enough, it states to Shake Well Before Use.

This is curious since the Lysol (Surface) Disinfectant Spray do not instruct you to shake the aerosol can. Hmmm... so yeah, it seems to be that way because of the different active ingredients inside?

Correct. The active ingredient in the Nuetra Air is the same one Oust used to use before it was discontinued. The same active is used in foggers for disinfection. The active ingredient in the surface spray tends to be harmful when aerosolized. Which is a bit odd because at much lower concentrations it's present in some consumables.

Hey man...all I know is it removes odors and disinfects germs. You’re getting all ‘Bill Nye the Science guy’ on me here. 😁
 
Shaking only makes sense when you feel something.

Paint cans often a small ball in it for stirring since all the pigments have sunken to the bottom over time.

Shaking a can without it might be useful for a small exercise but even that is doubtful.
