Abstract: There are herein disclosed a rubber composition for cleaning a mold which comprises 100 parts by weight of a natural rubber and/or a synthetic rubber, 2 to 30 parts by weight of an amino-alcohol salt in terms of an amino-alcohol content, 5 to 50 parts by weight of a glycol, 30 to 90 parts by weight of an adsorbent and 0.5 to 10 parts by weight of an organic peroxide, and a method for cleaning the mold by the use of this rubber composition.Since the amino-alcohol is fixed as the salt, the generation of ammonia odor at the time of kneading or at room temperature can be prevented to improve a working environment, and the volatilization of the amino-alcohol can be inhibited, whereby a mold cleaning effect can be maintained even after the lapse of a long time.
