Cleaning your pump sprayer after using Roundup is crucial to ensure it’s ready for your next job without any leftover chemicals. To clean your sprayer effectively, you should rinse it thoroughly with water multiple times, and consider using a mixture of water and bleach or ammonia for a more thorough clean.
Steps to Clean Your Pump Sprayer
1. Initial Rinse
Start by filling your sprayer with clean water. Spray out the contents until the tank is empty. This helps remove most of the Roundup residue.
2. Use a Cleaning Solution
For a deeper clean, mix a solution of water and either bleach or ammonia. Here’s how:
- Bleach Method: Add half a gallon of bleach to a tank full of water. Let the pump run for a few minutes, then spray it out completely.
- Ammonia Method: Mix one cup of ammonia with a gallon of water and spray it through the system. This helps neutralize any remaining glyphosate.
3. Final Rinse
After using your cleaning solution, fill the sprayer with clean water again and spray it out completely. Repeat this step at least two more times to ensure all residues are gone.
4. Inspect and Dry
Check all hoses and connections for any leftover liquid. If possible, blow out the hoses with compressed air to ensure they’re completely dry.
Tips for Maintenance
- Always label your sprayers if you use them for different chemicals.
- Consider having dedicated sprayers for herbicides and other chemicals to avoid cross-contamination.
- Store your sprayer in a cool, dry place to prolong its life.
FAQ
How often should I clean my sprayer?
You should clean your sprayer every time you switch between different chemicals or after using Roundup to prevent any chemical residue from affecting future applications.
Can I use hot water for rinsing?
Yes, hot water can help dissolve residues better than cold water, making it easier to clean your sprayer.
Is it safe to use bleach or ammonia?
While both are effective cleaning agents, always wear gloves and a mask when handling these substances, as they can be harsh on skin and lungs.
