Gravel and hills

Gravel drive dust is mineral

A large share of Erin properties sit on gravel or crushed-stone drives, and crushed stone in this county is dolomitic limestone. The fine dust it throws up on every trip is calcium-magnesium carbonate — pale, alkaline, and mineral rather than organic.

Dry, it sits loose and a rinse moves it. But it lands on paint that is damp with dew most mornings, and when it dries there it recrystallises onto the clear coat. That is the chalky cast on the lower panels and the bonnet that survives every wash, and it needs the mechanical clay stage rather than water to shear it off. It is the same material and the same mechanism as the quarry dust in Lannon, at lower concentration and from the driveway rather than the air.

Hill roads and brake dust

The Kettle Moraine terrain around Erin means steep, winding roads with a lot of braking, and brake dust is hot iron particulate. It embeds in the wheel finish and in the lower panels behind the wheels, where it corrodes in place and shows on light paint as rust-coloured specks.

The chemical iron remover dissolves it, and on a vehicle that does the hill roads daily the reaction on the lower rear panels is usually the most dramatic part of the job. Wheels get the same treatment, with the caveat that diamond-cut and painted wheels need pH-appropriate product rather than a strong acid.

Golf season on narrow roads

Erin Hills brings tournament and course traffic through the town on roads not built for it, and slow traffic on a rural road in summer means bug impact, tar softened in the heat and thrown onto lower panels, and sap from the tree cover along the verges.

Tar and sap are solvent-stage removals, bug residue is protein that etches if it bakes, and all three sit on top of the limestone film. The sequence is solvent for tar and sap, organic cleaner for the bugs, iron remover, then clay, then protection — because a vehicle going straight back onto a gravel drive needs something between the paint and tomorrow's dust.
