There are a few things you can do to keep your Pack and Play clean. First, make sure all of the pieces are in place before you start. This includes putting the pack away properly, filling it with fresh air, and closing all of the openings. Next, make sure all of the pieces are in their correct position. This includes putting the toy on the correct surface, checking that it is properly secured with screws or anchors, and making sure that any cords are connected correctly. Finally, be sure to regularly clean all of the surfaces inside and outside of your Pack and Play. This includes taking off any dust or dirt that has built up over time, cleaning any toys or accessories that may have been left behind, and wiping down any surfaces that may have been wet or dirty.
