Dennis, A couple of years ago i bought a m-cln. sprayer, mainly because i liked the 7qt. container and it did not work for me. It could not handel the heat. I called them and they said, send it back, so i did and they said their was nothing worng with it. After talking with them, i found out-they can't take more than 180or190 degrees. I have always used hf and been pretty happy with them.
