Hi,
Here are the care instructions from BabySafe website (same set of instructions for their newborn, infant and kid pillows):
(http://babysafe.sg/collections/latex-pillow/products/infant-pillow)
Hand wash with mild detergent is highly recommended. If machine wash, use a laundry net.
Rinse well in cold water
Press or roll latex foam carefully between two highly absorbent materials to squeeze out water
Do not wring or tumble
Dry under fan/warm air
DO NOT EXPOSE TO DIRECT HEAT OR SUNLIGHT
