Wood Restoration Cleaner

Wood ReNew is a biodegradable percarbonate-based wood cleaner that cleans and brightens grayed and weathered wood. Use it to return wood to its original natural color before applying any of our quality wood finishes.

Wood ReNew contains a thickener that helps it adhere to log walls and siding. Simply mix the Wood ReNew concentrate with water, stir, and liberally apply it to the wood with a mop or brush.

Wood ReNew will immediately begin to fizz and foam as it removes dirt and grime. After about 10 minutes scrub the wood with a medium-bristle brush and rinse thoroughly with clean water. Dirt, stains from mold and mildew, water stains, and UV damage will be gone and the wood will have a new, fresh look.

Wood ReNew should not be used for spot cleaning since it may cause blotching of the surface.

five star Mark on 6/21/17 – I used cleaner after cleaner on my 20 year old completely black log home and the only thing that worked was Wood Renew. It was like night to day, I couldn’t even believe it.

five star Joe on 5/9/17 – We recently moved into an older log home that had not been stained before and the wood was all silver from sun damage so we were told to try your Wood Renew product by a friend. This product was amazing! The logs went from grey to beautiful brand new looking wood which we were then able to stain with your Ultra 7.

five star Amanda on 3/2/17 – Good product once we figured out how to mix it! At first, we tested Wood Renew by mixing 12 Tablespoons per 1 Gallon of water using cold water, but it did not mix or thicken well. We checked with the Knoxville Perma-Chink Store and they suggested using warm water. Finally, it mixed well and we let it thicken up. Application was easy -- we used a mop and sponge to apply it to the logs and a pressure washer to wash it off. Our wood looks clean and brighter now. Thanks Perma-Chink!

four star Eli on 1/17/17 – Wood Renew was recommended through an on-line chat with Perma-Chink as a cleaner for our new to us older log cabin. It had not had any maintenance performed on it in years and had grayed considerably. The Wood Renew along with a pressure washer took away all the dirt, mold, and grayed wood and brought our cabin back to a like new appearance. From that point it was stain, topcoat, and enjoy!!

five star K Chen in WA (8/19/16) – Hi Amie, I've tried both permachink and other brands on cleaning the deck and i love how permachink is odorless and fast acting. i'm buying a gallon.

five star D Heinmann in WA (4/20/15) – "I was telling Kathy at the Redmond Store that I had power washed two of my walls last week. Because the last two walls were in worse shape I felt I needed to use some type of cleaner on them. Kathy told me that the Wood ReNew would work great and I should use it on all four walls. I really didn’t think I would need to since I had already power washed them. I went home and did use the wood renew on all four of the walls. I was surprised by how much more gunk came off the walls even after I had power washed them, so THANK YOU for recommending this product!

five star J Maxwell in NM (3/4/15) – "I used to have a lot of grayed logs on my home. Perma-chink had me use Wood Renew to get them clean. Now my home looks AMAZING!"

five star T Nolan in CO (2/23/15) – "I received an email coupon for the Wood Renew last year and decided to try it on my back patio. It was grayed out and looked really ugly…like it needed to be replaced. I called and talked with Shar in the Rifle office and she suggested I try this before ripping up my patio. I did and I am so glad I did!! I even sent her a bouquet of flowers thanking her for the great advice. Now my back patio looks great and I didn’t have to rip it out!"

five star M Breckenridge in CO (1/20/15) – "I attended a homeowners workshop in Colorado where I learned about a product called Wood Renew. The presenter showed us how Wood Renew worked on wood, amazing is all I can say, the Wood Renew took mold, sun damage, and dark discoloration as well as mill glaze right off with NO effort, an amazing product. Thanks Perma-Chink."

five star P Martin in MN (10/29/14) – "I purchased a foreclosed log home that was black from years of neglect. I was getting bids to have my home media blasted to take it back to bare wood. One contractor asked me if I’d tried Perma Chink’s Wood Renew. I had never heard of it but he gave me the number of the store in Rice and they sent me a sample the very next day. I was amazed, shocked and pleased at the job it did. It restored my logs to new saving me a lot of money, hassle and time. I would recommend this product to anyone with darkened logs or wood in general."

four star P Beatty in PA (06/07/2014) - "I’m glad it came in granule form so I could make it in batches without worrying about wasting product. Definitely a plus."

four star R Stolz in MT (03/05/2013) - "Wood Renew took the grey right off! The logs look like they did when we first built our house. Now we can start staining."

five star A Shea in CA (05/27/2012) - "You can see the wood transform from gray to natural wood right before your eyes. Amazing!"
