My bike chain cleaning spray has evaporated from its can while I stored it in my room after having closed it normally. I have used it only four times. Actually about a half of the bottle should be there, but it has evaporated. Is this possible? How and why?

  • What is it, WD40? – user37012 Mar 24 '18 at 9:52
  • Aerosol or squirty bottle? The former must be airtight, the latter doesn't need to be? Solvent or water-based? Could you smell it? – Chris H Mar 24 '18 at 11:10
  • I don't think this is answerable without more information about what exactly this product was. In particular, what's your reason for believing that half the bottle should have been left? Maybe you used twice as much as you thought you did. For now, I'm voting to close this question as unclear but I will, of course, retract that vote if the question is clarified. – David Richerby Mar 24 '18 at 11:39
  • You need to describe this "spray" better. What is the brand name? What terms are on the container to describe it? Is this an aerosol spray can or some sort of spray bottle? – Daniel R Hicks Mar 24 '18 at 12:20
  • Did it fall over at any point ? I've found spray cans empty or clogged up if they were lying down for extended periods. – Criggie Mar 24 '18 at 21:45
