Hey everyone! I'm new to gardening and finally trying to spruce up my neglected north-facing garden. Most of it is gravel with large pale stones that have turned green over time. Recently, after using a fire pit, I noticed that the stones around it went back to their original color. This got me thinking—could I use an electric weed burner to clean the rest of the gravel and even some concrete stairs that are also covered in green algae? I've tried pressure washing before, but it was a hassle due to poor drainage. Just to clarify, I mean an electric weed burner, not anything with a flame. Also, would something like Wet & Forget be a better option? Thanks for your help!

Check out Algon—it’s safer for the environment compared to bleach and just as effective. You can pour it on pavers or spray it on fences. I've been using it for a few years and love it!
You can definitely use products that you brush on or spray to help remove the green. I use salt on my brick patio, but just a heads up, it might stain concrete. Baking soda is another option to consider!
Using an electric weed burner could work, but keep in mind that the cheaper models with butane canisters are often ineffective. And it may not eliminate the roots, so if you're dealing with weeds, they might just come back shortly after.
Yes, but just know that you'll need to do it repeatedly for lasting results. There are also some treatments available that you can dilute, which may provide a residual effect for up to 9 months.
Thanks! Do you have any product recommendations for those treatments?
White vinegar mixed with water works well, or you could try red label hypochlorite. It's pretty effective!
Thanks! How would you go about diluting and applying the red label hypochlorite?
Thanks! What specific product would you recommend?
