My mom has a hole in the ground that she puts her clothes drying hanger in. Like this. The hole in the ground is a 2" or so pipe, set in concrete. The pipe has filled with gravel. Anyone have a tip on getting the rocks out? I can only get so many out using my fingers and then trying to use a set of chopsticks.
If the shop vac can’t get down far enough, duct tape a bit of PVC pipe or some other study tubing to the end of the vacuum hose. The standard nozzle might be too short or wide for getting where you need it, but it should be the quickest way to do what you need.
