Why it is worth doing

An engine bay collects road grime, oil mist, leaf litter, rodent nesting in winter and, in this climate, five months of salt spray thrown up through the underside. None of it hurts the engine much. All of it hides leaks, corrodes connectors and hose clamps over time, and makes a car look neglected to the two people whose opinion changes the number on it: a buyer and a mechanic.

A clean bay lets a leak be seen while it is a drip rather than a puddle. It makes a used car read as maintained the moment the bonnet is lifted. And after a Wisconsin winter it removes the salt that is sitting on every exposed metal surface under the bonnet, which is the one place a wash never reaches.

How it is done safely

Modern engine bays are full of electronics and a careless pressure wash is how alternators, sensors and fuse boxes get killed. We do not do that. Sensitive components are covered, the bay is treated with a degreaser and agitated by hand, rinsed at low pressure away from electrical connectors, and dried with compressed air so nothing sits wet in a connector.

Then plastics and hoses get a matte dressing that protects without the greasy shine that attracts dust and, on a hot day, drips. The bay looks clean, not oiled.

When to add it

Before a sale or a trade-in, always — it is fifty dollars against what a buyer or appraiser assumes when they lift the bonnet on a grimy bay. In April, after the salt season, on any vehicle that is kept long-term. And after a rodent has been in there over winter, which in rural Washington County is common and worth dealing with before wiring gets chewed.

It is an add-on to the full detail, the interior detail or the exterior detail. Ask for it at drop-off.
