Answer: A power washer will remove the moss without a bleach solution. There are moss control products on the market but they will only kill the moss, not remove it, so power washing will be necessary. You can rent a power washer. Just use plain water to wash the moss away. Bleach will harm any plants it comes in contact with and it will remain in the soil which could kill plants and lawns near your patio.
