20 Things That Damage Car Paintwork and How to Stop Them

20 Things That Damage Car Paintwork and How to Stop Them

Your car's paint does more than make it look good — it protects the bodywork from corrosion, sun exposure, and the wear and tear of daily driving. Yet, from bird droppings to cleaning sprays, many everyday things can quietly destroy that glossy finish. In this guide, we'll reveal 20 of the most common paintwork threats and exactly how to protect your car the smart way.

1. Bird Droppings

 

 

Acidic and packed with enzymes, bird droppings can eat into your car's clear coat in hours. Always remove them quickly with a soft cloth and a safe, pH-neutral cleaner like AutoManiacs Interior Cleaner.

2. Tree Sap

Sticky and acidic, tree sap bonds to paint and can stain or etch the surface. Use warm water and a microfiber cloth to gently remove it — don't scrape.

3. Bug Splatters

Dead bugs contain proteins and acids that cling to paint and break down the clear coat over time. Regular washing with AutoManiacs Car Shampoo can help remove them before damage sets in.

4. Brake Fluid

Brake fluid — especially older formulas — is highly corrosive and can strip paint within minutes. If spilled, rinse immediately and wash the area.

5. Gasoline Drips

Will gas damage car paint? Absolutely. Gasoline acts like a solvent, dulling your paint and leaving behind marks. Clean any spills quickly with water and shampoo.

6. WD-40 and Solvents

Can WD-40 damage car paint? Not directly, but misuse can soften protective coatings and attract dirt. Use only automotive-safe degreasers when needed.

7. Vinegar

Does vinegar harm car paint? Yes. Its acidity can break down waxes and coatings. It might clean windows, but keep it off painted surfaces.

8. Bleach

Will bleach hurt car paint? Definitely. It's a harsh chemical that can permanently discolor and deteriorate paint. Avoid bleach-based products entirely.

9. Rubbing Alcohol

Will rubbing alcohol damage auto paint? In high concentrations, yes. Dilute it 10:1 if you must use it, and rinse thoroughly afterward.

10. Household Cleaners

 

 

Clorox wipes, Lysol, Windex — they're great on countertops, but they can strip wax, dull paint, or leave behind streaks. Stick to car-specific products only.

11. Shaving Cream

A classic prank — and a serious hazard. Shaving cream can stain and etch paint overnight. Remove it immediately with a foam cannon and gentle shampoo.

12. Silly String

 

 

Does silly string ruin car paint? It can. The dyes and propellants react poorly with paint if left on too long, especially in the sun.

13. Road Salt

Essential for winter safety, but it's corrosive. Salt can work its way under paint and speed up rust. Rinse your car regularly and apply a ceramic coating for long-term protection.

AutoManiacs Tip: Our Ceramic Coating Spray adds a hydrophobic barrier that keeps salt and other contaminants from bonding to your paint.

14. Tree Pollen

Sticky and abrasive when dry, pollen can cling to paint and create micro-scratches. Wash it off frequently during spring with a microfiber towel and soft foam.

15. Parking Lot Mishaps

Shopping carts, door dings, even careless passersby — these scratches are some of the most common paintwork issues. Park smartly away from high-traffic areas.

16. Sunlight and UV Rays

UV damage causes paint to oxidize, fade, and lose its richness. A ceramic coating with UV blockers can dramatically slow the process.

17. Hard Water

Minerals in hard tap water can leave chalky spots that etch paint. Always dry your car with a high-absorbency towel like the AutoManiacs Drying Towel.

18. Insects Nesting in Grilles or Seals

Some insects are acidic and may stain paint when crushed. Periodically clean air vents, rubber seals, and around the badge area.

19. Acid Rain

 

 

Pollution in the atmosphere can turn rainwater into a mild acid that eats into paint. Wash your car after rainstorms and store it under cover when possible.

20. Poor Washing Techniques

What ruins car paint faster than anything? Scrubbing with rough cloths or using the wrong soaps. Always use the two-bucket method and pH-neutral shampoo like AutoManiacs Car Shampoo for a swirl-free shine.

Types of Car Paint Damage (And How to Spot Them)

Understanding the kinds of damage your car can suffer will help you act early:

Clear Coat Damage

  1. Light scratches, swirl marks, and fading
  2. Often caused by poor washing techniques or environmental exposure
  3. Usually fixable with polish or a light correction product

Base Coat Damage

  1. Deeper scratches or abrasions that cut through the clear coat
  2. Often from stone chips or harsh chemicals
  3. May require touch-up paint or professional refinishing

Chemical Etching and Staining

  1. Caused by acid rain, bird droppings, or chemical spills
  2. Leaves visible outlines or pitting in the surface
  3. Can sometimes be removed using clay bars or polishing compounds
Tip: Apply AutoManiacs Ceramic Coating to prevent etching and simplify future cleaning.

What to Do If Your Paint Is Already Damaged

Not all hope is lost! Here's how to assess and fix the problem:

Surface-Level Issues

  1. Use a clay bar to remove bonded contaminants
  2. Follow up with a polish to restore gloss
  3. Finish with a protective coating

Moderate Damage

  1. Try paint-safe compound polishing
  2. Use touch-up pens for small chips
  3. Seal with ceramic spray for long-term protection

Severe or Deep Scratches

  1. If you can feel the scratch with your fingernail, it's likely through the base coat
  2. Professional paint correction or body shop work may be needed
AutoManiacs has Interior & Exterior Bundles to get you started with scratch-safe DIY solutions.

Protecting Your Paintwork: Smart Habits to Follow

  1. Wash weekly with the two-bucket method
  2. Use pH-neutral products and microfiber towels
  3. Dry completely to avoid water spots
  4. Avoid parking under trees or in high-traffic zones
  5. Use a ceramic spray every 1–3 months
