I thought I would pass this information on to those of you that have a SpringFree Trampoline (or really any trampoline). If you find that your feet (or your children’s feet) are dirty and black after they jump it’s because the mat is dirty but I’m sure you figured that out already. The tip is on how to clean it. Just washing it down may not do it so SpringFree suggests that you use dish soap and scrub the top and bottom of the mat – The bottom might be hard to do but maybe you could put the kids to work on that!. Once you scrub it down then powerwash it. If you don’t have a powerwasher maybe a High Powered hose nozzle will do the trick.
