A electric pressure washer located in my garage with at least a 50’ hose. Quality foam cannon. (Griot’s for me) Ego 765 blower and quality long lasting sealant applied before the wash. (the secret to fast wash and dry) The foam part with a very light contact with your wash mitt. 1/2 hour for me but it is a Miata including a quick microfiber dry after the blower.
