Hand-wash with pH-neutral shampoo every 2-4 weeks; never use household dish soap or detergent because it can strip the sealant. Skip automated drive-through washes because the brushes can mark the finish.
Plan to refresh Jet Seal once or twice a year. When water stops beading after a fresh hand wash, that is the easiest trigger to book the next application.
For tree sap, bird droppings, or insect residue, rinse and remove within 24 hours. The sealant buys reaction time, but contaminants left for days can still etch the clear coat underneath.
