How To Clean Wood That Hasn’t Been Treated

If you have wood that hasn’t been treated, it more than likely will end up turning grey, as well as getting covered in all sorts of dirt and rubbish. Before you make any kind of attempt to apply a finish to it, it’s important to use a wood cleaner on the surface in order to remove all of this dirt, as well as restore the original colour. Additionally, it will also help the finish get worked into the wood really well, especially since dirt can generally prevent something like this from being applied very well.

What Other Tools Do I Need?

Here are some of the other useful tools that you can utilize when it comes to using a wood cleaner:

  • A nylon brush or broom that has stiff bristles
  • A synthetic roller or brush
