Abstract: An apparatus for sanitizing is provided. The apparatus includes a housing having a reservoir for retaining sanitizing fluid. The apparatus also includes a holder disposed beneath the housing. The apparatus further includes an applicator pad received by the holder and adapted to be in selective fluid communication with the reservoir. The applicator pad includes a dome-shaped portion having a substantially hemi-spherical shape configured to extend into an interior region of a bell of a stethoscope head when the bell is placed over the dome-shaped portion.
