How to clean deck which has grooves in timber

[JARAN]

Hi. Want to repaint my deck but the timber has grooves in it. Its time to clean and update it as it is looking shocking. People have suggested that I turn the boards over (on the smoother surface) before repainting. Its a large deck and I don't really want to do that, if I can help it.  Does it really make a difference ? Surely a scrubbing brush will help to uplift dirt from the grooves ??

Hello @JARAN 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about cleaning and painting your deck.

There was a similar question asked a few weeks ago, I suggest having a look at the discussion - How to update backyard fencing and pool ... - Page 2 by @Firsttimerhelp5. I suggested that aside from using a standard floor sander, it will be necessary to use a detail sander to clean the grooves of the decking panel. This will add an extra bit of effort to the sanding job, but if done properly will give your deck a superb finish. I propose doing this as a three-person job, one to use the orbital floor sander the other two to use detail sanders to do the grooves.
