12 Common Car Detailing Mistakes—and Why You Should Avoid Them at All Costs!

iStock_000007332972XSmall(2)We don’t want to be “that guy.” You know the one—the guy who constantly tells you how to do your job (or how “you’re not doing it right.”)

So please think of this post as more of a public service message.

In conjunction with Mothers, Meguiar’s, and other automotive detailing experts, we’ve put together a list of common detailing mistakes and why you should avoid them. With a full season of car shows and cruises just beginning, it’s best to eliminate these mistakes now:

1. Washing in direct sunlight—or washing a car that’s hot.

We’re starting with the most obvious here.

It’s widely accepted among most detailing companies and professional detailers that you should NOT wash your car in direct sunlight. Some argue that it’s bad for your vehicle’s finish, but at the very least, it makes the job much, much harder. Because the water and cleaner/soap dries quicker in the sun or on a hot surface, you’re more likely to get water spots. And you may even notice swirl marks in your car’s paint after washing.

If you absolutely must wash your car in the sun, keep the surface cool with a regular spray of water.


2. Using your drying towel to remove dirt you missed during washing your car.

All you’re doing here is grinding the dirt into your finish.

By using your drying towel to remove dirt, you risk scratching your paint. And while we’re on the topic, you may want to pass on the squeegee for drying your vehicle’s surface. A squeegee can pick up and drag dirt into your paint.


3. Pouring waxes and polishes directly on the vehicle’s surface.

Don’t pour liquid waxes and polishes directly on the surface of your vehicle. This can lead to dark, uneven streaks in your finish. Instead, pour these types of the waxes and polishes directly on to your applicator.


4. Using solvent-based tire and rubber protectants.

Avoid solvent-based tire and rubber cleaners and protectants.

Mothers suggests checking your rubber cleaner bottle for distilled petrochemicals, which can adversely affect your tire’s surface integrity.


5. Cleaning your wheels and tires last.

Many of us were taught to clean our vehicle from the top down.

However, this does not include the wheels and tires.

In fact, you should clean your wheels and tires first, since they are most often the dirtiest parts on your vehicle. This will prevent you from splashing wheel well dirt and grime on your just-washed vehicle surface.

6. Using dish soaps or detergents.

Truth is, dish soaps are convenient and cheap to use, and they’re even somewhat effective at cleaning cars. In fact, they’re a little too good—harsh even. Dish soap and detergents are formulated to remove grease and wax and can strip away automotive waxes and sealers that are there to protect your vehicle’s finish.

Instead, use a purpose-made automotive wash.




7. Using ammonia-based glass cleaner. 


Mothers Glass Cleaner is ammonia-free.

Most household glass cleaners contain ammonia.

Ammonia not only stinks, but it can be damaging to upholstery and dashboard surfaces if spilled or dripped. Use an ammonia-free glass cleaner instead.


8. Treating stained upholstery areas only.

When you’ve got a nasty, dirty stain on your vehicle’s carpet, it’s only natural to focus time and energy on that one spot. But unless your vehicle is almost brand new, the entire upholstery is probably dirtier than you think. By cleaning just the individual dirty spots, you could wind up with a few very clean areas and the rest suddenly looking dirty.

That’s why it’s important to give attention to your entire interior instead of just particularly bad spots. Apply upholstery cleaner evenly to the entire area of your upholstery.


9. Treating all plastics the same.

Not all plastics are the same.

So don’t treat all your plastic surfaces the same. Mothers recommends using a penetrating protectant on soft plastics and dedicated plastic polish on harder surfaces like gauge cluster lenses.


10. Overwaxing.

Can you have overkill when waxing? Yes.

In most cases, two coats of wax will do the trick. The initial coat provides the foundation, and the second coat will cover any areas the first go-around may have missed. Any further coats will likely not adhere and will simply be wiped off with buffing.



Meguiars Microfiber Towels.

11. Using a chamois for drying.

Please use a microfiber towel.

Microfiber towels will dry the surface while babying the finish. Chamois were once the go-to drying tool, but they contain very little nap to absorb left-over particles on the surface. The smoothness of the chamois will instead grind these particles back into the surface and create swirl marks.

It’s the same reason you shouldn’t use an old T-shirt to dry your precious vehicle.



12. Improper car towel cleaning.

Whether you use microfiber towels or simple, soft cotton towels, you’ll want to clean them properly after use. Don’t use a fabric softener—it can leave chemicals in the towels that are detrimental to your wax.

  1. really great tips,thank you

  2. This is so stupid, the author probably never did a car wash before

  3. I let a hard rain clean My truck!

  4. Twelve very good tips .

  5. I’ll disagree with number 5. I use a a separate tire mitt for doing my wheels/tires last. if I did them first I’d be using contaminated water to wash my car. Other than that, spot on. Sorry, bad choice of words.

    • Good practice to use atleast 2 wash medis like you do
      but use the 2 bucket wash system.
      One 5 gallon bucket witu your soap the other with jist rinse water
      both should have grit guards at the bottom lf each bucket
      after you clean a section, dip sponge into rinse bucket prior to going back into wash bucket

    • The bucket for the wheels should have your brushes dipped in them while cleaning . You should then foam the car and use a mitt to agitate the soap and dirt . Then Another bucket with plain water to regularly rinse your mitt from dirt buildup

  6. I did not know that!

  7. John Minette says:

    Wash your car in the rain. Save money and time.

  8. Use water if you want it to rust away before you trade it in for a new one.

  9. Russell Joseph says:

    there is nothing wrong with solvent based tire care products. Prove me wrong and show some proof on why they negatively affect surface integrity. Water based products don’t last as long

    • Lmao, use your head and think about it, these tire cleaners cause s chemical reaction that literally burns a layer golf the rubber off, leaving it soft and wet looking. If you can’t see the issue with that you probably shouldn’t be allowed to handle a hose let alone a car.

  11. I’ve always used two buckets,and wheels were always last on the cleaning list.
    Don’t need any brake dust being ground back into the finish.
    Actually I’d use the last of the clear water in the second bucket when doing the wheels.Also don’t throw out those old toothbrushes!They work great for nooks and crannies where wax seems to hide.
    They also work great for getting into tight spots on custom wheels

  12. Carwash Aficionado says:

    The biggest tip of all is missing – NEVER fucking EVER use a sponge for cleaning your car. It’s basically like using a sandpaper. Buy a microfiber mitt.

  13. With exterior black plastic parts. Like fenders on a Wrangler. I soak them with Black Restore or Back to Black right before I wax. Anyone who has accidentally dripped wax on those parts will know what I mean. Years of white wax stains.

  14. When I was a youngster, Many years ago, I worked for a service station that did a full hand car wash on any vehicle that had shop work done. The owner insisted that kerosene was added to the wash water. The vehicles did turn-out much shiney’er than when they came in! Of course this is way back when gas stations had bulk oil, kerosene, etc., in tanks with hand cranked pumps. Gas was around 23 cents a gallon for leaded regular

  15. I’m an automotive painter, and I don’t disagree with any of these points. Although, if this is a used car that I feel needs to be polished to bring back the new paint look, I would use dish soap to do an initial cleaning on the cheap. But I would suggest “Detro Clean” to completely remove all contaminants from the surface before doing your first buff/polish. Detro Clean is especially good for wheels and tires, to clean road grime. I’ve used it to clean semi-truck frames which were caked in road-grime and oil/grease/dirt, etc. And while not advertised as a tire-dressing, I use Meguiars #40 to dress my tires because I don’t care for the “wet look”, and #40 gives tires that brand-new tire look–not shiny, just deep black.

  17. I have used original formula Murphy’s Oil Soap for washing my vehicles for decades. The “soap” not only cleans the car, but the oil seeps into difficult to reach crevices and prevents rust. It even makes the paint “bead up” when it gets wet the next time. Have to dry the vehicle right away as it can leave spots.

    While my vehicle is dripping wet after rinsing it, I spray the entire vehicle, glass and all, with detail spray. I then wipe the vehicle dry and this technique prevents water spots. It works like magic. Try it, you’ll be sold.

  23. Dennis Lynch says:

    The car detailing is a crucial assignment that has to be carried out systematically for ensuring a safe ride. There are some specific procedures that we must follow while detailing our intermediary. Sometimes, an untrained professional also makes mistake while detailing a car. Apart from these above twelve preventable mistakes, some other mistakes including- washing a hot car or washing the car under direct sunlight, pouring waxes directly on the surface of the vehicle, using dry towel to remove the sludge, using low quality dish soap or detergents, that many operatives do while detailing their speed machine on their own. Thus, prior to stepping into the process, you need to fix an appointment with a car professional- so that you can ensure a safe and error-free execution of the undertaking.

  41. Great tips! I would just like to emphasize that dish soap is not a car cleaner. It will oxidize your exterior and dull your paint’s finish. It might be a cheap and “effective” alternative, but it will also damage your car. Spend a few bucks on a proper car shampoo to make sure your car is in tip top shape.
