    Abstract: An objective of the present invention is to provide a burnishing pad, capable of removing dirt by burnishing a place (i.e., a dirty point) onto which dirt attaches to impart sufficient luster, and being biodegraded; a burnishing machine equipped with the burnishing pad; and a burnishing method using the burnishing pad. The burnishing pad of the invention is comprised of a lock-like fiber composite in which adjacent fibers are bonded at intersection thereof, wherein said fiber is at least one selected from the group consisting of a vegetable fiber and an animal fiber. And another burnishing pad is a fiber composite comprised of thick fibers of 150 ?m or more in fiber diameter. These pads can be equipped with a porous supporting layer, respectively. The porous supporting layer has a mean 5% modulus strength of 20 N/5 cm width or more at 70° C. and a unit area weight of 100 g/m2 or less.
