We are going to show you how we cleaned our fence rock or gravel edge that borders our fence. Over 4 years, the edging was overtaken by weeds, pine needles, pine cones, and other debris. Our method was to use a disposable BBQ grate as a filter for the rocks. We scopped out the rocks and debris on to the grate and then removed any large items such as weeds or large pine cones. We then shook the grate and this did a great job of filtering the debris. In the end, this took us about 2 hrs of work to clean 20ft of fencing with 2 people working on it.
