Can I wash the synthetic grass in the washing machine?

We have tested this and found it isn’t the best solution. The agitation of the washer after 4 washes began to wear the rubber coating on the bottom. The best way to wash it is with your hose, or in the shower or bath during the colder months. You can also rinse the grass with a vinegar solution or 1-2 capfuls of bleach to a gallon of water.
