Q: Can I use Wet & Forget on lichen? How do I apply it?

A: Yes, Wet & Forget will work on lichen, however the application instructions are different. Since lichen is a tougher growth, you will need to spray the area twice.

Dilute the Wet & Forget as instructed on the bottle, then spray the affected area, wait 15 minutes, then spray the area again.

This double application is required when treating lichens in order to clean the surface properly. Read more about lichen are how you can remove it using Wet & Forget here.
