Query: Great idea but unreliable. Must be a better one somewhere

I thought this a wonderful idea after ruining several pans using the aerosol sprays that leave a sticky residue. I bought two - one for olive oil, another for vegetable oil for coating bake pans. After about a month the veggie oil began squirting rather than spraying. No matter how hard I pumped, could not make it spray. Emptied it, thoroughly cleaned in hot soapy water. Then it worked...for about a day. Back to squirting.The one with the olive oil still sprays but unevenly and creates a mist in the air like air freshener. Maybe that's why they call it "Misto".
