Are you looking to sell your house and want to add value to it or you just want to improve the curb appeal of your home? A wood deck can be a great investment. Hence, it is vital that you protect it by cleaning it regularly to prevent stains and extend its life. Pressure washers are effective for removing stain and debris as well as saving time and energy. However, not all pressure washers are appropriate for deck cleaning as very high pressure washers can damage the wood and leave lap marks on the decking.
