Which Cleaning Solution Works Best for a Clogged Epson WF-2650 Printhead?

Question:

I have an Epson WF-2650 printer with a severely clogged printhead. I bought two bottles of BCH Technologies' Printhead Cleaning Solution—one clear and one green. Which one should be diluted, and which is best to use for this printer? Can I use them undiluted?

Answer: 

Understanding the Epson WF-2650 Ink System and Clog Severity

The Epson WorkForce WF-2650 uses pigment-based ink, which is notorious for forming extremely stubborn clogs—especially if the printer has sat unused for long periods. Unlike dye-based ink, pigment particles are larger and more prone to drying inside the nozzle channels. This makes the WF-2650 one of the harder models to unclog once issues set in.

Choosing the Right BCH Cleaning Solution

We offer several cleaning formulations tailored to different ink types and clog severities. Since your printer uses pigment ink, both the Clear and Green solutions you have can be effective—but with some nuance.

Clear Cleaning Solution

• Use for: Routine maintenance and mild-to-moderate clogs.

• Ink Compatibility: Safe for both pigment and dye inks.

• Strength Level: Mild.

• Dilution Needed? No. You can use this solution undiluted.

This is the safest option and is highly recommended for general users. If your clog isn’t too deep or if you’re trying to prevent future clogs, the Clear formula is a great starting point.

Green Cleaning Solution

• Use for: Stubborn pigment clogs and more aggressive cleaning cycles.

• Ink Compatibility: Works for dye, pigment, and now sublimation inks.

• Strength Level: Medium-strong.

• Dilution Needed? No. It is ready to use right out of the bottle.

The Green solution is a step up from the Clear. It's still non-corrosive and printer-safe, but its stronger formulation makes it ideal for heavily blocked nozzles like what you’re experiencing in the WF-2650.

What About the Strongest Solutions?

If you’re dealing with a printhead that's completely unresponsive, you might be tempted to try the Red or DTF MaxStrength™ solutions. However:

• The Red Cleaning Solution is highly potent and meant for professional-level clogs. It’s safe for pigment use, but we don’t typically recommend it unless you’ve tried Clear and Green with no improvement.

• The DTF MaxStrength™ Solution is not safe for the WF-2650. It must be diluted before use and is intended specifically for DTF white ink applications. Using it undiluted on an Epson pigment printer like the WF-2650 could cause irreversible printhead damage.

Can I Use the Solutions Undiluted?

Yes, you can use the Clear, Green, and Red solutions undiluted for direct application to your WF-2650. Only the DTF solution requires dilution and is not suitable for standard pigment ink systems like yours.

Additional Tips:

• Warm the solution slightly (around 40°C/104°F) before use to improve its effectiveness.

• Always use proper cleaning tools like syringes and silicon tubing for direct flushing.

• Avoid soaking the printhead for more than 24 hours, especially with stronger solutions.
