Logs and timbers as well as most other milled material has oil, dirt and just plain old "yuk"

on the surface so you must clean all that will be exposed to finish.

Rent, borrow, or buy a pressure washer that you can adjust the pressure. DO NOT !!!! set the

pressure above 750 psi to wash the material since high pressure will drive the dirt into the

wood. Also hold the nozzle away from the logs and timber and at an angle.

You can use prepared products that you can buy at the Home Centers to "Bleach" the wood

and remove any mildew etc. or you can use a mixture of one part household bleach to 4

parts water, pour into a low pressure garden sprayer and apply to the logs and timber. You

will need to use a good quality nylon brush and scrub a little or "much" depending on the

extent of dirt. Allow to set or rest for about twenty minutes then wash with the pressure

washer or garden hose with a good spray nozzle on the end. You must get all the bleach

solution off the logs since the bleach will dry the wood unnecessarily.

You need to apply your pesticide before the logs become completely dry. We highly

recommend Pene-Treat insecticide. It is waterbased and contains Borax. Will not harm

animals or humans but it sure does a number on the wood chewing insects.
