Polyurethane foam can be cleaned with a mixture of vinegar and water. Pour the solution on a soft cloth and rub the foam, rinse, and let dry.
Density is weight divided by volume. Measure the weight (with a scale), calculate the volume (which is easy to do if the foam is rectangular in shape - you might even want to cut out a rectangular piece, if your foam has an irregular shape), and divide the weight by the volume.
