Jason from Se Wisconsin writes

Will Bifen IT leave a permanent residue on the siding of a house?

I have a customer who is saying they have a white reside on their siding and the rain hasen't washed it off yet. Will it come off in time or do I need to pressure wash their entire house? They are very good people so I want them to be happy!

Answer:

According to the manufacturer, Bifen IT is equivalant to spraying plain water as it dries clear and doesn’t stain. The residual outdoors is 30 days so any white film would fade over time.
