Removing Ink Stains: Thermal Metal Spoon Hot Disposer of Pigments - Video

The method of cleaning pen ink stains on white fabric fibers utilizes thermal energy transfer through a metal conductor medium. Oil or gel-based pen ink generally contains polymer formulas and organic solvents that are sensitive to extreme temperature changes. When exposed to a stable high temperature, the chemical bond in the ink pigment will experience the weakening of the adhesive structure in the pores of the fabric.

This process begins by heating a stainless steel tablespoon over a gas stove for a few seconds. Stainless steel metal was chosen because it has an efficient thermal conductivity value to absorb and retain heat evenly across its surface. After feeling hot enough, the convex part of the spoon is immediately applied to the surface of the fabric that has been scratched by ink.

When the hot surface of the spoon is pressed and rubbed slowly on the scribble, the hot temperature is immediately transferred to the fabric fibers. This thermal effect triggers the evaporation of residual solvents in the ink as well as melting the wax component or color pigment binding resin. As a result, the pen ink that originally binds firmly to the cotton thread will break down and fade quickly.

This heat-based stain removal technique is very effective for certain types of ink that are reactive to high temperatures without damaging the integrity of the surrounding textiles. The characteristic of thick white fabric fibers is able to withstand momentary heat exposure from metal without experiencing deformation or burning effects. The final result shows that the fabric surface is clean again and free from blue scribble residue instantly.
