Cleaning the Evo Oil Sprayer is quick and easy. The bottle section can either be rinsed with water or put into the dishwasher. The actual trigger sprayer can be cleaned by simply spraying warm soapy water through the sprayer, then thoroughly rinsing with warm tap water. Look for the Evo twist-on funnel, so you can refill your Evo bottle easily. Look for the Evo bands, so you can label your bottle in a unique and fun way.
