Help getting purple bird dropping stains off my cedar deck
I'm really hoping somebody can offer me some guidance.
We just finished our cedar deck here in southern Ontario and days later it's covered in purple bird droppings.
I power washed it as soon as possible to try to keep them from staining but some of them didn't come off. I only used water and no soap of any kind as I wasn't sure what would be good idea to use.
I was going to wait to stain until next spring because it's really not warm enough right now to do it. My understanding is that I need some relatively warm days on a constant basis. It's been warmer than normal here but not enough I don't think.
Can anyone recommend a cleaner that I can use to get these stains off?
And if and when I do get it cleaned, is there some sort of product I can apply that will help protect the wood from more stains penetrating it? I want to stain it next year so I didn't think I could put anything else on it until I do that.
