Pretty much the same (partially fill, pick it up, shake A LOT and pour water out do this at least twice, more depending upon what I just applied; THEN partially fill, pressurize and spray)
EXCEPT, I remove the sprayer tip AND the plastic piece underneath (with 2 or 3 holes in it) until whatever chemical was left in the hose and wand is flushed out, entirely. Then I'll run pressurized rinse water though just that 2- or 4-hole orifice followed by the complete end nozzle assembly. Kinda OCD but, I've found this step to really, really lengthen the life of that small but critical part and totally prevent eventual clogging that critical piece under the end nozzle.
Occasionally or, depending upon what I just applied, (I.e., certain "sand-like" water dissolvable granules, aka- WDG's) I will add a couple drops of dishwashing liquid and repeat the process to flush all suds out.
THEN, once done washing, I hold the wand up and depress the trigger several times, allowing any remaining water "trapped" in the hose and wand to drain back down into the tank, which I turn over to empty.
Finally, a finger tip of silicone on any "O"-rings or plastic parts at the nozzle end and a spritz or two of aersol silicone spray in between any plastic moving parts and Fluid Film in between any parts involving metal and hang her upside down til next use.
WHAT I HAVENT FUGURED OUT IS HOW DIFFICULT IS IT TO TO ALL THE WASHING AND RINSING ALL OF IS DO WITH THE NEW BATTERY POWERED, ELECTRIC BACKPACK SPRAYERS ... (or is that a question for a different thread?)
