You can prevent a smear from accidentally washing-off a slide by using heat to fix the cells to the slide and it can be achieved by following this procedure:
- Allow the smears to air dry first.
- Fix the cells to the slide by gently heating.
- Hold the slide on the frosted end with your clothespin found in your cabinet.
- Do this by quickly passing the underside of the slide over the flame of a Bunsen burner.
- Each time, touch the slide to the back of your hand - when it becomes uncomfortable, it is done.

smear should be rinsed with distill water so that all the small particles attach to the smear will washed away such as some time the crystals of dye are attached to the smear which give the illusion of microbial cell some time, distill water is used because it is free from other microbial cell and ions which can harm the smear.
