TIP: Cleaning Trellis easily with high strength Vinegar...

[Tarquin]

We have a couple of wooden Pergolas. Between the uprights and shaded from the sun we have two 6' x 5' trellis panels which are covered in green Algae after the winter months.

When cleaning some nearby paving with 40% strength white vinegar the overspray cleared the Algae without any further assistance so I put some in a sprayer, lightly misted the trellis and an hour or so later the green had gone. By next day the wood generally looked cleaner.

Mask up and wear eye protection if you try it and make sure there's zero wind.

Thank you friend for the very helpful tip.

Thank you for sharing this tip! Using high-strength vinegar as a natural cleaner is a great idea. I'll definitely try it on my pergola, as it seems to be an effective and eco-friendly way to remove algae. Safety precautions like wearing a mask and eye protection are important, especially when dealing with strong vinegar. Ensuring there is no wind is also a good point to prevent accidental spray drift. Thanks again for the advice!
