I'D LIKE TO GET SOME FEEDBACK FROM OTHERS ON THE TOPIC OF THE MOST EFFICIENT PROCESS FOR CLEANING AND SEALING CEDAR SHAKE SHINGLES. IS THE "APPLE SAUCE" A GOOD CHOICE FOR CLEANING? A ROOF I'M GETTING READY TO CLEAN IS MOSTLY JUST GREYED AS I REMOVED MOST ALGAE A FEW YEARS AGO WITH A DETERGENT/BLEACH MIXTURE. I SEE MOST PEOPLE HERE MENTION THE USE OF SODIUM HYDROXIDE FOR ASPHALT SHINGLES.
DOES ANYONE USE "KORKERS" OVER THEIR SHOES TO SAFELY WALK A ROOF? I HAVE AND THEY'RE GREAT!!!

I'VE USED CHEVRON SHINGLE OIL ON WOOD AND IT SEALS AND STRENGTHENS VERY WELL. HAS ANYONE ELSE EXPERIENCED USING IT?

PLEASE OFFER SUGGESTIONS FOR THE CLEANING PROCESS.
