It’s a go-to first step for proper surface preparation—especially important for reliable adhesion before painting, or for a clean base before applying wax. Dilute to suit the job, wipe down with a damp sponge or cloth, then rinse thoroughly with fresh water for a streak-free finish. For sailing in Ireland, it’s a practical choice for regular washdowns after salty passages, and for deeper degreasing jobs around the cockpit, decks, and bilge areas.
