In this study, microscopic visualization imaging of microscopic microbubbles in water was conducted to elucidate the cleaning mechanism of oil and grease stains. We constructed a visualization experimental apparatus using a microscope lens and succeeded in taking microscopic images of microbubbles adhering to fiber surfaces. To elucidate the cleaning mechanism of oil and grease stains, visualization experiments were conducted on oil and grease coated on glass surfaces. Fluorescent paint was added to the grease and LIF measurements were performed. In this experiment, it was not possible to accurately evaluate the detachment with video images, so the visualization method will be improved in the future.
