I have a customer with Ipe that I wash every couple of years. They use an oil to make it look great after cleaning I have honestly had to throw as much pressure as possible on parts of it to get rid of the old oil before they reapply
Ipe is also called ironwood and can take a lot of abuse I’m also a woodworker and Ipe will dull a blade quickly when working with it I’ve actually used a turbo nozzle on it to get it clean if they wait too long before cleanings
