Know before you buy : Non aerosol pump spray. The oil mist has extremely high requirements on the nozzle. New upgrade spray nozzles sprays finer and more even. Because of the different oil, the concentration is different, the effect of creating an oil mist will of course be different. We suggest you put the sprayer higher when you use olive oil, keep the bottle staying vertical as possible to get better shaped mist. If in the correct use method, can form good oil mist, and meet the used needs of most people. But for customers who require extremely very high atomization effects, please purchase carefully. Because I don't want to cheat the consumer. Warm tips : We recommend to clean it before using. Please do not sterilize directly with boiling water, avoid being burned. If you don't use it for a long time, please keep it clean. Because the oil congeals easily in winter, it may clog the tip, causing a spray. If so, simply run the nozzle in warm water for a few seconds and it will return to normal. Don’t put the impurity in it to avoid sprayer nozzle blocked. Reasonable use and maintenance of the product can extend the service life.
