A device for wringing soiled baby diapers after the diaper has been cleaned of excess soiled materials in the bathroom water closet. This invention consists primarily of two wringer rollers secured to a main attachment frame which can be secured to the conventional standard bathroom water closet seat bolts. When the device is in place below the water closet seat the device does not interfere with customary water closet usage. When it is desired to use the Soiled Diaper Wringer Device the water closet seat and cover are rotated to the usual up position at which time the device is fully exposed for wringing a soiled diaper. This configuration features an outer roller that is mounted to the main attachment frame by a pivot bolt which allows the user to rotate the outer roller outward thereby providing space for diaper insertion. Resilient elastomer bands provide wringer squeezing pressure as the diaper is pulled through the rollers. The invention has the novel features of providing a highly sanitary and hygienic technique for treating soiled baby diapers while at the same time can be installed on existing or new bathroom water closets without interfering with normal customary toilet bowl usage. The unique physical relationship of the two rollers, combined with the pivot action of the other roller, together with single end roller mounting provide for simplicity and ease of installation and operation.This is a continuation of application Ser.
