Kosher you utensils for Passover: 

Kitchen utensils used year-round may not be used for Passover without Koshering. Most metal utensils can be koshered for Passover. Clean them well, and do not use them for a minimum of 24 hours. Bring them to Kosher at the Rabbi's backyard. 
Please check with the Rabbi regarding glass, plastic, other utensils, and in-home Koshering.
