Maintenance free decking, railings, lawn furniture all should mean a little less work, right?  We were getting very frustrated that our white maintenance free deck railings looked worse and worse every year and scrubbing or power washing them didn’t get rid of the black grime on the edges.

The photo above is right after scrubbing!  But, we finally found a solution.  After making sure bleach won’t damage them or any surrounding surfaces, use a paintbrush to liberally apply a mixture of 50% warm water and 50% bleach.  Let it sit for about 3-5 minutes and then hose off.  Apply a second coat to really tough spots.  Yes, it was that easy!
