Log Wash

Liquid concentrate for cleaning and conditioning logs/wood and stained finishes.

Ph neutral.


The initial reason we developed Log Wash was as a mild cleaner for cleaning finished exterior surfaces. We found that all of the products typically recommended for general maintenance cleaning like Spic & Span, Mr. Clean or even mild dishwashing soaps softened finished surfaces during the cleaning process. This resulted in potential finish damage especially if a pressure washer or a brush was used. It turned out that the one thing these cleaners all had in common was their high pH. When we tried the Log Wash formulation we found that it hardened the surface of our finish system and no damage occurred to the finish even with vigorous scrubbing. It was only later that we discovered the benefits of using Log Wash on bare wood.

So what are some of the attributes that make Log Wash such a remarkable product for cleaning bare wood?

First and foremost is its pH. It is one of only a handful of cleaning products on the market that has a slightly acidic pH similar to that of wood. This means that when applied to wood it does not disrupt the wood’s chemistry thus avoiding many of the discolorations attributed to highly alkaline solutions like bleach or strong acids like oxalic acid. Another feature of Log Wash is that it’s easy to tell when it has been sufficiently rinsed off. While rinsing Log Wash it will foam as long as any residue remains on the wood. When the foaming stops it’s a good indication that the wall has been adequately rinsed.

One of the biggest surprises we encountered with the use of Log Wash on bare wood has been how well it removes some types of discolorations due to tannins or chemical imbalances. There have been several occasions when discolorations we thought would be difficult if not impossible to remove ended up being no problem at all with the application of a solution of two cups Log Wash per one gallon of water.
