When your fountain pen starts skipping, runs dry, or won’t let go of the last ink color, it’s time for a good flush — and you don’t need the old ammonia-and-dish-soap recipe to do it. Dr. G’s Fountain Pen Flush is ammonia-free and non-corrosive, made to clear out old ink and free a sluggish feed without harming your pen. Dr. G’s prescription for good pen hygiene: a regular flush. Also available as a concentrated Travel “On the Go” flush.

When to flush

• When you change inks and need the old color fully out.
• When a pen has sat inked-up too long.
• When you have nib creep, skipping, or poor flow.

How to use it
Pour a little Dr. G’s Fountain Pen Flush into a clean ink sample vial or any small container (or mix up the “On the Go” Concentrate with water). Rinse your pen nearly clear with water, then fill it with the flush. Let it sit a few minutes if there’s dried ink, empty, and repeat as needed. Finish with a plain water rinse.

Don’t forget the cap
Squirt a little flush into the cap, let it sit a few minutes, and it will dissolve the old dried ink in the inner cap. Swab the inside with a cotton swab and finish with a quick water rinse.

Safe to use
Tested on our Premium Fountain Pen Replacement Sacs and a range of materials — it won’t harm sacs, celluloid, hard rubber, metal, or acrylic.
