Winter’s salt, grime, and cold can leave your car battered, from corroded undercarriages to weakened batteries. Spring maintenance restores performance and prevents damage. This guide is for car owners with beginner to intermediate skills, detailing 10 DIY tasks to clean and check your vehicle after winter. With clear steps, safety precautions, and practical tips, you’ll ensure your car is ready for warmer months and avoid costly repairs.
Why Spring Maintenance Matters
Winter stresses car systems: salt accelerates rust 10 times faster than water, per the American Society for Testing and Materials, and batteries lose 30% capacity below 32°F, per AAA. Tires, wipers, and fluids also suffer, increasing breakdown risks—15% of spring roadside calls stem from winter neglect, per AAA. Unchecked damage (e.g., rust, worn brakes) can cost $500–$5,000, per automotive repair estimates, and reduce fuel efficiency by 5–10%, per the U.S. Environmental Protection Agency (EPA).
Spring maintenance costs $50–$200 in materials and takes 3–5 hours, saving $200–$1,000 versus shop fees. Ranging from simple (washing) to moderate (fluid checks), these tasks suit DIYers building skills. By cleaning and checking your car, you’ll boost longevity, safety, and performance.
