The general rule
Most drivers benefit from a full detail every three to four months — roughly once per season — with a maintenance wash every two to three weeks in between. That rhythm keeps contaminants from bonding to paint and stops interior grime from becoming permanent stains.
Adjusting for New England seasons
Winter is the toughest season in Massachusetts. Road salt and brine eat at paint, wheels and undercarriages, so plan a deep clean before the first snow and another in early spring to remove the salt that's built up. Spring pollen and fall leaves can also stain paint if they sit too long.
Commuters, families and pet owners
If you commute on I-93 or the Mass Pike daily, carry kids, or drive with a dog, you'll likely want interior cleaning every one to two months. Crumbs, spilled drinks and pet hair work into fabrics fast.
Protected cars need less
A ceramic-coated car stays clean longer and washes faster, so many owners stretch full details to twice a year with simple maintenance washes in between.
