I have a wrap around deck (cedar,I think)with a roof overhang. sunlight varies by location. Nothing has been done to it in many years. I have a serious algae problem. I trie 30 Second Cleaner but it had minimal effect. What can I do to remove the algae pror to a brightner and what stain do you recommend. I'm thinking twp cedartone. help
TWP will work well. Try Wet and Forget to remove the algae or bleach.
