摘要: Provided is a sticky cleaner whose adhesive face can be easily renewed and whish is less susceptible to roll-loosening. The sticky cleaner provided by this invention comprises a PSA tape having an adhesive face on the first face of a substrate. The PSA tape forms a PSA tape roll wound with the adhesive face on the outside. On the first face of the substrate, the PSA tape comprises a first layer formed of a PSA and a second layer formed of an acrylic viscoelastic material. The adhesive face comprises first sections where the first layer is exposed and second sections where the second layer is exposed. The second sections protrude further out of the PSA tape roll relative to the first sections. The PSA tape roll shows an unwinding force F0 at 0° C. and an unwinding force F30 at 30° C.
