Can I Spray Blue Indicator Dye?

Blue marking dyes can be a useful tool for identifying treated areas and improving application accuracy. However, it's important to understand that blue dyes may have unintended effects on the diaphragm pumps commonly used in battery-powered sprayers.

Using Blue Landscape Dye

While many users successfully apply blue dye products, blue dye can be particularly hard on industry-standard diaphragm pumps used in battery sprayers. Continued use may increase the risk of premature wear, reduced performance, clogging, or pump failure over time and void the sprayer's warranty.

If you choose to use blue dye, please do so with the understanding that there is an increased risk to the sprayer's pumping system. It is crucial to rinse the sprayer out after use.

Clean And Inspect After Every Use

To help minimize potential damage, we strongly recommend cleaning the sprayer immediately after each use.

Required Cleaning Procedure

1. Empty all remaining spray solution from the tank.
2. Fill the tank with warm, soapy water.
3. Run the cleaning solution through the hose, wand, and nozzle.
4. Completely drain the system.
5. Repeat this process a total of three times (triple rinse).
6. Inspect and clean the inlet filter before storing the sprayer.

Inlet Filter Inspection

Pay special attention to the inlet filter's stainless steel mesh screen:

1. Remove the filter and inspect it for dye residue or debris.
2. Clean the screen thoroughly if any buildup is present.
3. Ensure the screen is completely clear before operating the sprayer again.

A clogged inlet filter can restrict flow, reduce sprayer performance, and place additional strain on the pump.

Other Products That May Affect Pump Life

In addition to blue dyes, several other products are known to be particularly demanding on the diaphragm pumps. View the articles below for more info:

Best Practices for Maximum Sprayer Life

Proper cleaning and maintenance are the best ways to maximize the performance and lifespan of your electric sprayer. In addition:

• Follow all chemical label instructions.
• Rinse your sprayer thoroughly after each use.
• Triple-rinse after using blue dye.
• Never store chemicals in the tank for extended periods.
• Inspect seals, filters, and hoses regularly.
• Store the sprayer clean and dry between applications.
