Many novice gardeners are guilty of storing herbicides or fertilizers in their sprayers. And I was no exception!
That’s why when my niece developed a keen interest in lawn care, I was determined to help her avoid this mistake. I knew that she is a huge fan of the Roundup herbicide, so I thought it’d be a good idea to tell her all about how to neutralize Roundup in a sprayer.
Read on if you, too, want to learn about it.
How To Neutralize Remaining Roundup In The Sprayer?
Whether you own a handheld or backpack sprayer, both of them have identical parts, viz., the nozzle and the tank, meaning the cleaning process will also be similar.
Step 1- Clean The Tank
Start by emptying the tank, but get in touch with the local authorities to understand how to properly dispose of the herbicide. If you need to clean the sprayer urgently, then store the leftover liquid in a plastic bottle or similar container and keep the lid tightly screwed on till disposal.
Then, prepare a solution with some soap and warm water and dip a sponge in it. Use this sponge to thoroughly clean the insides of the tank. You may need to repeat this step multiple times, depending on the intensity of the herbicide buildup.
Step 2- Flush The Nozzle
Cleaning the nozzle may be a little challenging since the internal cavities and curves are practically impossible to access with a sponge or cloth. Hence, the best way to clean it is by flushing it with an effective Roundup neutralizing agent.
For this, fill the cleaned tank halfway through with plain, warm water or the same soapy solution and continue spraying until the tank is empty. I’d strongly recommend doing this around the area where you usually apply the herbicide to prevent contaminating the rest of the lawn.
Once this step is over, get hold of an ammonia-based cleanser to flush the wand and nozzle. I usually take about 3ml of household bleach and dilute it with approximately 380 ml of water.
Again, fill the tank halfway through with this cleanser and spray it about 5 to 6 times. Leave the rest of the solution in the tank overnight- this will help break down any stubborn Roundup residue.
Spray out all the solution the next day and take some more warm water to rinse the entire sprayer, hose, and wand. Likewise, use an old toothbrush to clean the nozzle from the outside.
Final Words
Perhaps, the best way to prevent the buildup of herbicides is to avoid storing them for too long in the sprayer. Remember that keeping the Roundup solution in your sprayer for more than a couple of hours can cause it to form a clump, gel-like substance, which clogs the tank and nozzles.
Similarly, clean the sprayer immediately after applying the herbicide, but don’t forget to wear your gloves and protective eye goggles before doing so. This will provide you with optimum protection against unwanted exposure to the chemical.
That’s it for today. See you again!
