Does vinegar change the pH level of treated wood to the degree a commercial cleaner does? My wife likes to be 'green' so we used a water/white vinegar (2:1) mix to scrub some algae and mold from our previously unstained pt wood retaining wall. Do I still need to use a Brightener to adjust the pH level before applying a stain/sealant?
Vinegar lowers the pH level similar to a wood brightener while a deck cleaner raises the level. Vinegar is not really a cleaner but acidic in nature. Using a brightener may help to even out color but hard to day for sure.
We have a stained deck in fairly good condition. Resealed this spring with Thompsons, but have mildew problems due to a damp season and trees. What is the best option for cleaning that won't harm finish or plants? Was planning to use vinegar.
Use a deck cleaner not vinegar.

What can be used that will not hurt vegetation around the deck? Most people have decks in their backyards surrounded by grass, trees, and plants.
A deck cleaner that is biodegradable will work and not harm the plants if you rinse well.
