Zest-it® Artists Technical Pen & Nib Ink Cleaner
Soak the nib section for as long a necessary to dissolve the dried encrusted ink from the nib and its inner workings.
Check progress after 10 minutes, water rinse and repeat as required. Any nib units and pen parts that cannot be separated may need longer soaking.
When clean and free moving, water rinse, dry and reassemble. (One very old badly ‘solid/dried-up’ Isograph nib took two days of soaking but it came back to life). Patience and persistence pay off!
The solution can be re-used many times for nib cleaning, it may look very dirty but it will still work.
Please note: This product contains citrus terpenes from the peel of the fruit and therefore there may be slight variations in the colour from clear to pale yellow. This does not affect the quality of the product.
(Technical Pen Cleaner is stronger than Fountain Pen Cleaner).
