Whenever my queen excluders or screened covers get all blocked up with beeswax, I use a heat gun to melt it off. I used to try to scrape them clean but it took forever; the heat gun does a better job in a fraction of the time.
The heat gun I have is 1500 watts, has two settings, and costs about $20. I use it for lots of things around the apiary, but mostly for melting wax or propolis. In addition, it works for many odd jobs around the house. It’s one of those things I didn’t know I needed until after I brought it home.
You can get heat guns plain and inexpensive, or you can find spendy ones with all kinds of fun features you probably don’t need.
If you use it on excluders or wire covers, it helps to tip the pieces backwards at an angle to the ground. If you hold them vertically, the melted wax runs down along the wires, but if you hold them at an angle, or lay them flat, the wax drops off onto the ground.
