Rohrer & Klingner Reiniger (Pen Flush / Cleaner)

Rohrer & Klingner Reiniger (Pen Flush) is a purpose-built pen cleaner designed to safely and effectively remove dried ink, pigment residue, and stubborn buildup from fountain pens. This 45mL bottle will last for many cleanings. Just fill your pen through the nib, wait 5 minutes, and empty/rinse.

It’s especially useful for deep cleaning after using permanent or high-maintenance inks (like pigmented or iron gall), helping restore smooth flow and consistent performance. Gentle on pen materials but strong where it counts, Reiniger is an easy, reliable way to keep your pens writing the way they should—whether you’re doing routine maintenance or bringing a neglected pen back to life.
