I use the Sta-Flo and have couple spray bottles I got at the dollar discount stores. They also have them in Wal-Mart back in the beauty section. Some in the kitchen section near the ironing boards and starch sections. I use the small bottle and don't mind refilling. If any is leftover after I'm finished, say an ounce maybe 2 I may spray a couple strip scraps or just pour it down the drain then clean it out with a little dish detergent. Just put a little in the bottle and fill with water. Give it a good shake then run it through by spraying and repeat with warm clear water. You'll have a clean bottle to work with on the next project.
