Dirt, pollen, mildew, mill glaze, and graying all keep stain from bonding — and a finish applied over a dirty surface will fail early no matter how good the product. At Wasatch Timber, we carry the Sashco cleaning and prep products that get bare logs ready to accept stain and look their best.\u003c\/p\u003e\n\n\u003ch3\u003eClean and Brighten Before You Stain\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCPR Log Cleaner \u0026amp; Brightener\u003c\/strong\u003e cleans and brightens bare logs and wood, removes surface dirt and pollen, and kills mold — bringing dull, dirty logs back to life and giving you the clean canvas a quality stain needs.
