Do not put too much force on the staining wells, when removing them.
Pulling up or out too hard may damage the wells. They should be clipped
gently into and out of place on the stainer plate.
Place the stainer wells in a tray with enough methanol to completely cover
them. Agitate the tray to remove any air bubbles.
4. While the wells are soaking, use a soft cloth or paper towel to clean the
stainer plate. Rotate the plate manually to clean the entire surface.
5. After the wells have soaked in the methanol for ten minutes, remove them
from the tray and dry them with paper towels.
