using the microwave to dry slides

Our lab stains 800-1000 H&E slides every day. Because of the volume we find it necessary to use a kitchen microwave to dry the water from the slides before staining. I was wondering if other labs use this technique with success. Is there a way of QCing this procedure? Also, we are looking into an automatic stainer. Has anyone found one that keeps up with the volume? Thank you so much in advance for your help. Paula
