What to do about ugly green algae on siding 

I have been enjoying spending time outdoors with all this warm, sunny weather we have been having. I was puttering around in my garden earlier today, enjoying the warmth but also feeling a tad overwhelmed by all the work that needs to be done.

We have a cute little shed that my husband built that has a little window box full of spring bulbs. I noticed that the shed and window box were covered in a green algae. After a wet winter algae often grows on the north facing side of walls. I decided that removing that algae was the first spring cleanup chore I would tackle.

I read an article on Yahoo that said all I needed was a spray bottle and some Clorox .  I followed the instructions below and Voila! a clean shed.

Fill a spray bottle with half Clorox and half water. (This will be very strong). It should be strong enough to cut off anything. Make sure you have a bucket of rinse water, with a sponge and some dry rags or cloth. The spray bottle is used for small areas, where the algae grows. Spray the algae generously and let it set for a few moments. Soon you will see streams of green running from the spray you just put on. Now just wash it off with your rinse water and sponge. Take your cloth and dry the area. Sometimes, if the algae is thick, it might make for a greenish stain. simply repeat the process and rinse it off again.(Source Yahoo Voices)
