You might be able to use it the next day, but in that it's very different
from formaldehyde... If it no longer has any odor, I'd chuck it. And it
will soon polymerize, that is make big blobs. Which is one reason I use it
at 15%... It does the job as well, and doesn't keep any worse.
Formaldehyde working solution of course kept indefinitely.
