We conducted a cleaning verification of the "GKU = Gasron Supply Unit" installed at our factory. The GKU in question was installed in 2013, and we selected one that had not been wiped down for over six months. We used lukewarm water and a sponge purchased from a 100 yen shop. Surprisingly, just one pass was enough to wipe away the dirt from the coated surface. The wiped surface maintains an appearance that is comparable to when it was first produced. [Verification Summary] ■ Subject: Gasron Supply Unit installed in 2013 ■ Tools Used: Lukewarm water and a sponge purchased from a 100 yen shop ■ Verification Result: Dirt on the coated surface was wiped away with just one pass *For more details, please download the PDF or feel free to contact us.
