Bring Your Logs Back to Life.
Clean and brighten bare logs and wood, remove surface dirt, and pollen, and kill mold for maintenance, and keep your logs looking fresh with CPR Log Cleaner and Brightener.
CPR is used to clean and brighten uncoated wood that is dirty, faded, or gray from UV exposure. Mix CPR to the brightening solution strength for use on new construction just prior to staining to remove dirt and grime from logs during the building process and to break down mill glaze. Mixed at the log cleaning solution strength—use for periodic cleaning of stained logs to extend the life of your stain.
One container makes 4 to 8 gallons of solution depending on cleaning strength desired.

Common Questions From Our Network of Pros
CPR is great on almost all wood species except Redwood, some Cedar, and Douglas Fir. It will turn those woods a funky color. We always recommend doing a test with CPR before applying to the entire home to ensure there won’t be discoloration issues.
A pump sprayer works great for CPR. Apply from the bottom up, then rinse from the top down. A stiff bristle brush may be necessary for more stubborn patches.
No. This is normal for CPR and other types of powder products. As long as 90% of it dissolves, you’re still getting the right effects from the product. Warm water will help dissolve the powder better, so if you have warm water available, use it, but it’s not necessary for CPR to work properly.
The key is to make sure the wood is back to neutral after using CPR. Use pH strips, widely available on the internet or at pool/hot tub supply stores. Make sure you’re at neutral after rinsing to make sure you got it all off.
