“Regular old Dawn liquid dish soap won't damage a vehicle's clear coat but is not ideal for general maintenance washing, since it will remove wax, leaving your vehicle unprotected,” the website reports.
No, Dawn dish soap doesn't ruin car paint, but it can strip wax and protective coatings, leaving the paint vulnerable. Use soaps designed for cars.
Car wash soap: Choose a biodegradable, pH balanced soap that creates suds to lift dirt from the paint surface without damaging wax or coating. Microfiber towels: These are the softest and least likely to scratch the vehicle's paint. Store them separately in the garage to keep them clean and free of dust and dirt.
"pH neutral soaps are the safest and are not going to do anything drastic to the paint or whatever is covering the paint," says Kosilla. Concentration/Value: A more concentrated soap will last longer and potentially offer better value for money, depending on the price-per-ounce and dilution requirements.
Dawn dish soap and all similar brands are not good for washing cars because they strip the wax off the clear coat finish. They won't ruin the actual paint but over the years you will see the clear coat finish become dull. Use car soap.
Car wax contains oily, plant-based substances with similar properties to butter or cooking spray. So as you can imagine, dish soap removes wax from your car same way it removes grease from your skillet or frying pan after your morning bacon. Chances are, you won't notice this happening right away.
You'll want to use a fine-grit sandpaper (like 800 grit) to gently sand down the flaking areas. The goal here is to sand just enough to remove the loose clear coat without damaging the base paint. Always sand gently and evenly. After sanding, use a microfiber towel to wipe down the area.
For the DIY enthusiasts, household items such as dish soap, baking soda, or baby shampoo can serve as car wash substitutes. While these aren't as specialized as commercial products, they provide an immediate and accessible solution for car cleaning.
Touchless car washes, which use high-pressure water and gentle soaps, are a great option. This type of wash will effectively remove dirt, grime, and other contaminants without risking scratches or damage to the paint.
We recommend using a specialty automotive car wash instead of dish soap, as some dish soaps can strip the wax and damage the car's finish. Car wash soaps are specifically developed for automotive paint surfaces, so you can be sure you won't cause any damage while washing away dust picked up from the road.
While some car washes may be safe bets, others might not be worth the risk. An automatic car wash can damage your paint if you don't take care of your car afterward. If you don't dry it off thoroughly after washing, the water can create scratches in the paint that will show up later.
Commercial car washes use water efficiently and safely
In contrast, washing your car at home means all the dirt, oil, exhaust fume residue, soap chemicals gets washed into storm drains and into our region's streams, lakes, and waterways, where they can harm wildlife and destroy sensitive ecosystems.
The Environmental Working Group gave Dawn a 'D' grade because of it containing methylisothiazolinone, which is a "High Concern: acute aquatic toxicity; Some Concern: skin irritation/allergies/damage". Sounds delightful, right? Dawn also contains 1 4-dioxane which is considered a groundwater contaminant.
There are plenty of household items you can use to wash your car. For the car exterior, you can use baking soda, peanut butter, and baby shampoo. If you're dealing with dirty windows or windshield wipers, you can use a mixture of rubbing alcohol, vinegar, and water to clean them.
Washing your car with a water hose is never the best option. By doing this, you could potentially damage your vehicle's paintwork.
Using a high-quality car wash soap and wash mitt will help you avoid much of the damage caused by dirt and other contaminants. At Turtle Wax, every car wash soap, sponge and microfiber towel we sell is safe for automotive use. We recommend a high-foaming, lubricating car wash detergent like our M.A.X.
As others have already mentioned, touchless is the only way to go if you want to use an automated car wash and avoid any paint damage.
Keeping your ride clean helps keep it in good condition. If the weather's not too harsh where you live, washing your vehicle every two weeks is a good rule of thumb to help your car last longer. However, if you apply a coat of wax at the end of each cleaning session, you may be able to wash it less often.
Yes. Nonabrasive dish soaps are safe to use when washing a car. Soap maker Dawn even recommends using its dishwashing soap to remove grease and grime from exterior car surfaces. Although dishwashing soap is acceptable under certain circumstances, it should never be the first choice for a well-maintained car.
Dish soap does not belong on your ride! It might seem like a quick fix, but using dish soap or other household cleaners on your car is a big no-no. Sure, it's easy to grab, but those harsh degreasers strip away your car's protective coatings like wax, sealants, or ceramic finishes.
White vinegar
This home staple is a versatile multi-purpose cleaner and is great for many surfaces, including the exterior of your car and upholstery. While white vinegar is acidic, when diluted it won't damage your car paint – just avoid using it regularly and only when there is dirt that just won't budge.
UV radiation: The sun causes slow, cumulative damage to clear coat over years by heating up layers of paint and causing them to separate.
But just because it won't dissolve your car's clear coat doesn't mean that using it on paintwork is a good idea. We already mentioned the smell and the greasy appearance that WD-40 leaves behind.
Applying the white vinegar spray removes water spots, mineral deposits, and tree sap stains without damaging the clear coat.
