A guide to different brands of Pilates equipment and how to care for them. Seems the warm soapy water is a consistent theme and highly recommended.
I like this suggestion,
“Make an equipment maintenance notebook, with a section for each piece of equipment. Note purchase date, serial number, and if you cannot find a serial number, assign one yourself. For each machine, keep track of maintenance, inspections, any parts that are replaced (note recommendations on spring replacement above), and any issues that may arise (including the circumstances, if possible) and how they were resolved. This information can be very helpful if a problem arises.”
