What dirties solar panels in Auburndale
Twin-lake mineral mist
Homes near both Lake Ariana and Lake Myrtle pick up a light mineral film most mornings, similar to Winter Haven but on a smaller scale given Auburndale's more modest lake frontage.
US-92 corridor road film
The highway connecting Lakeland and Winter Haven carries steady commuter and freight traffic, leaving a road film on homes closest to the corridor.
Sports complex event dust
The Lake Myrtle sports complex draws heavy seasonal traffic for tournaments, kicking up extra dust on nearby homes during peak event weekends.
Lovebug season
Standard twice-yearly lovebug residue across the city, requiring a pure-water soft-bristle clean rather than a plain rinse.
