Or spray made for testing. Commercial guys use it.
I replace them every 10 years. Mine are hard wired with 10 year Li.
battery back up. I do same with gas detectors.
So, do you replace them because:
a) It's been ten years, or
b) Because they failed the smoke-in-a-can test?
Some fails some does not but to be on the safe side.
Doesn't cost a lot to replace them all.
Makes sense. At least it keeps you from blowing smoke.
