I got one of Roxanne's glue bottles because of the tips. I continue to refill it with Elmer's Glue now and if the glue gets a little thick I just add a bit of water and shake it. For the tips, I take them off after every use and soak them in a cup full of hot water. Have a straight pin at the sink too just in case I have to encourage the glue to come out of the tip. Then I just let it drain dry at the sink before I put it back on the tray with the glue. I found the hot water did the best in cleaning out the glue for me.
