I have read the wiki on sterilizing razors, and have followed the protocol of 10 minutes in ethyl alcohol and 10 minutes in hydrogen peroxide, followed by very hot water rinse, on used razors I have bought. Never got sick, but the razors all seem to develop some spots that won't wash away. Am I making a mistake? Any suggestions, either for sterilizing or for getting rid of the spots?

Thanks,
