7 Common Summer Car Cleaning Myths Busted: What You Think You Know Might Be Hurting Your Vehicle
Summer is the season of road trips, drive-thrus, lake days, and sticky fingers on steering wheels. Naturally, you want your car looking and smelling great—but there’s a lot of misinformation out there about car care, especially when the temperatures rise.
At H+H Shine Shop, we hear a lot of car cleaning “advice” that doesn’t hold up. So, we’re setting the record straight by busting some of the most common summer car wash myths—so you can keep your vehicle clean, protected, and shining all season long.
Myth #1: “Rain is a Free Car Wash”
The Truth:
Sure, rain might knock some dust off your car, but it’s far from clean. In fact, rain often contains pollutants and acidic compounds from the atmosphere. When that water evaporates, it leaves behind water spots, grime, and even corrosive residue that can damage your paint over time.
Pro Tip: After a rainstorm, rinse and wax can help neutralize harmful residues and restore your car’s shine. Be sure to check out our Super Shine or Whole Shabang Wash!
Myth #2: “Hot Weather Helps Dry Your Car Faster, So It’s Fine to Wash in the Sun”
The Truth:
Washing your car in direct sunlight is a recipe for streaks and water spots. Soap and water dry too quickly in high heat, especially on dark-colored cars, making it harder to get a streak-free finish—and may even lead to etching.
Best Practice: Get your car washed early in the morning, or during the cooler evening hours for the best results.
Myth #3: “You Only Need to Wash the Exterior”
The Truth:
Interior grime builds up even faster during summer. Sand from the beach, dust from windows-down drives, spilled drinks, and sweaty gear all take a toll. A clean cabin not only improves comfort—it protects upholstery, eliminates odors, but also keeps allergens at bay.
Don’t skip: Vacuuming, wiping down surfaces, and cleaning glass regularly during the hot months.

Myth #4: “Bug Splatters Will Wash Off Later”
The Truth:
Insects may seem harmless, but bug guts are acidic, and the longer they sit, the more damage they do. Left alone in the sun, they can permanently etch your paint or clear coat.
Solution: The Shine Shop bumper blaster will take care of those stubborn bug spots. Included with all our washes!
Myth #5: “Automatic Car Washes Will Damage Your Paint”
The Truth:
This myth stems from outdated systems. Modern car washes—like those at H+H Shine Shop—use soft-touch technology that is safe for today’s finishes. On the other hand, using the wrong sponge or towel at home can cause micro-scratches.
Bottom line: A professional wash is often safer and more effective than DIY when done right.
Myth #6: “You Don’t Need Wax in the Summer”
The Truth:
Summer is just as harsh on your car as winter. The sun’s UV rays, bird droppings, tree sap, and acid rain can cause oxidation, fading, and stains. A good wax or sealant protects your paint from these elements, makes washing easier, and keeps your car looking showroom-ready.
Consider: Upgrading to a wax package during summer months for added durability. Check out our Super Shine or Whole Shabang Wash!
Myth #7: “Dish Soap Works Just Fine for Washing Cars”
The Truth:
Dish soap is great for cutting grease—but that’s exactly the problem. It strips away protective waxes and dries out rubber trims and plastic finishes. Using it on your car is like washing your hair with laundry detergent.
Use instead: A pH-balanced car wash soap, like H+H Shine Shop has, formulated specifically for automotive finishes.
