Hello Everybody, I got a Gillette slim twist with white handle and I like it. It's generally in good nick, however it has yellowish patches on the handle(not very obvious) I been cleaning it with soap, fairy liquid and tooth paste but couldn't get rid of it completely. Has anyone dealt with this situation before and succeed? Also why the handles crack apart from obvious reasons like dropping etc. as it was a job to find one without a cracked handle. Thanks a lot in advance and have a good weekend.
