Is there a secret on mixing powder pre-spray for the hydraforce sprayer?? I normally always use Liquid because I hate the powder. It always seems to clog up my sprayer only when I use powder.. I tried a new pre spray tonight a sample pack that I received. And it works fantastic on my restaurant. I loved it however half way through it clogged up my sprayer. I mixed it separately and another container with really hot water. Shake it around a bit.. and then poured it in my hydro Force sprayer container. It look like it was dissolved. But it's still clogged up my sprayer. I transferred it over into a pump sprayer and sprayed it that way. Is there a trick?
