Fan of the Month: See how Jeff Annihilated Algae on his Siding

Jeff H. in Cape Cod, Massachusetts had a big problem: algae. Slimy, disgusting green algae had taken over the entire north side of the home Jeff had lovingly built, turning the beautiful white cedar clapboard into a neon-green eyesore.

Jeff didn’t want to strip the natural patina off of the cedar with a pressure washer or bleach-based cleaner, and he was beginning to feel like he was running out of options. Then Jeff tried Wet & Forget Outdoor, and was absolutely amazed with the results!

Now this retired builder would never use anything else to take care of algae on his home. Read on to hear Jeff’s story, and see more amazing before and after photos!

Green Algae: a Nightmare on Siding

“It was a real mess!”

Jeff H., Cape Cod, MA

Jeff built a beautiful white and red cedar home for his family 30 years ago. He built their home with loving attention to detail and used the best materials so that the home would stand the test of time.

But then disgusting green algae began colonizing the north side of Jeff’s home, taking advantage of the damp sea air. Before Jeff knew it, the algae had completely taken over the white cedar clapboard, and the outside of the house was a real mess.

“Over the last few years, the algae really started to develop,” Jeff said with frustration. “It was a real mess!”

Why Bleaching or a Pressure Washer weren’t the Answer

Jeff wasn’t sure how to kill algae on his white cedar clapboard. He was worried about stripping the wood’s protective patina or damaging his home’s water seal.

“White cedar clapboard turns gray naturally,” Jeff said. “It’s the wood’s own protection, and it builds up over the years. I didn’t want to bring a pressure washer in and just blast all that off.”

Jeff had seen neighbors with white cedar homes use pressure washers to clean their siding, and saw how the natural gray patina was gone afterwards.

“You blast all of the protection away, and then it has to start slowly building up again,” Jeff said “Now the wood has to go through that whole process again of protecting itself.”

As a builder, Jeff was also concerned about the potential damage that could happen to his home’s water seal if he hired a pressure washer.

“You blast all that water on the house with such a massive force, it could maybe force its way around the clapboard and trim and damage the tarpaper underneath, and let water into the walls,” Jeff said. That’s why, when a contractor came by his home with a pressure washer and a big price tag, Jeff told the man “no, thanks.”

Jeff had seen other neighbors of his hire contractors to spray a harsh outdoor cleaner on their homes, also with less than ideal results. “It seemed to turn the wood almost orange,” Jeff said.

So, when Jeff decided to try a bleach-based outdoor cleaner on his home, he tested it on a small, inconspicuous area first.

“It was awful!” Jeff said, exasperated. “It stripped off all the beautiful gray protective coating on the wood and left it bare, bright white. I don’t want bright white, stripped wood, and I don’t want orange. I just want the natural gray wood, and the algae gone!”

Wet & Forget Outdoor to the Rescue!

“The whole thing was beautiful. Absolutely flawless!”

When Jeff heard about Wet & Forget’s gentle formula, he thought he’d give it a try.

“I got a couple of bottles, and diluted it like the instructions said,” Jeff told us. “I bought one of those backpack-style garden sprayers so I could strap it on while I climbed the ladder to spray, and it was really easy to apply.” Now Jeff’s part was done, and Wet & Forget Outdoor did the rest of the work for him to rid his home of ugly algae.

Jeff treated his siding with Wet & Forget Outdoor in May, and he had planned to re-apply in November because of the severity of the algae infestation. Instead, Jeff was astonished at how fast Wet & Forget Outdoor completely eliminated the green algae on his home.

“Within 3 or 4 months, it was all just gone!” Jeff exclaimed. “The whole thing was beautiful. Absolutely flawless! Now I’m done with the algae!” With no second application needed, Jeff plans to use the extra Wet & Forget Outdoor to wipe out the black algae on his front stoop.

Jeff is so thrilled with the results he got with Wet & Forget Outdoor, he invites people over to see how great his house looks. He even told us,

“If you hear from anyone on Cape Cod who has any doubts about using Wet & Forget, give them my address and tell them to come and take a look!”

And Jeff has just one message for any of his neighbors who are thinking about trying a bleach-based product, a pressure washer or anything else besides Wet & Forget Outdoor to clean their cedar homes:

“You’re out of your mind.”
