Remove sand from Sony ZV-1?

Is there is a standardized way to clean out foreign objects from the camera? If so, where can I find directions to open the camera and clean it?

My Sony ZV-12 displays the message "Please turn the camera off and back on", then turns off when I turn it on. I took it to the local camera store, and they said it's because of the sand stuck in the camera, and to send it to Sony.
I don't see the ZV-1 listed here.

@oldturkey03 Thank you for your answer!

I tried all the ideas from the website link. While I did remove grains of sand, the lens still won't open up. Now when I turn the camera on, there is no attempt for the lens to open and expand. No machinery sound either. The Turn Camera OFF then ON message still appears.

• Would replacing the lens solve the issue?
• Where would I get lens replacement parts?

Would it be better to sell the camera for parts and buy a new one?

Thank you for your advice. Apologies for the late response; I'm a parent of two kids, so getting around to fixing things takes some time. :)
