Will An Automatic Carwash Break The STI Wing?

The STI wing is a modification to the stock wing on a vehicle that includes a spoiler. It’s typically made of carbon fiber, and you install it in the front under the bumper or rear with outboard end caps.

The wing increases downforce on drag racers and sports cars at high speeds and promotes stability when cornering at high speeds.

No! An automatic Carwash isn’t going to break an STI wing. They need to be stronger and certainly more powerful to damage the material. You would need something hard and rough to break the wing, like sandpaper.

So, if you take care of your STI wing by washing it with a sponge and mild dish soap, an automatic carwash will not break it.

Note that not all car washes have the same power output or brush specification. Some have more aggressive brushes because they’re made for removing dirt and grime from vehicles.

The brushes do cause some damage to the paint, but it’s minor. Regular car washes can cause more damage than automatic car-wash.

As for washing your car with a sponge and soap, avoiding using terry cloth towels is always smart. They’re one of the most common causes of swirl marks on paint.

And, if you choose to use a chamois, make sure to wring it out well after each use.

Once you finish your carwash, dry the lower part of your car with a towel. Don’t touch the upper portion of your vehicle.

Can A Subaru Go Through A Carwash?

Yes! A Subaru can go through a drive-through carwash. Subaru vehicles are designed with a protective coating that withstands rain and the carwash.

However, over time your clear coat will inevitably wear away no matter how often you wash your car.

The solid bars of the carwash scrubbing brush and soap can quickly remove this layer of protection and cause damage to your vehicle’s finish.

It is better to clean your car by hand or have it professionally detailed when it needs extra TLC.

The other option would be to purchase a self-serve carwash. These facilities are touchless, and technology has evolved to use the wash without brushes.

Just drive your vehicle through the tunnel, and they automatically spray soap on it without scrubbing. The carwash brushes and scrubs do a good enough job.

Furthermore, the folks in charge of ensuring the self-serve carwash have the proper portions of rubber sealant and car wash soap on hand.

So the bottom of your car does not end up stuck to a floor covered with thousands of gallons of other people’s filthy water.

Subaru recommends washing your car with a bucket and sponge to keep it looking great. Use a mild cleaning solution made especially for cars. Rinse the car thoroughly afterwards.

Before you wax your car, wash it thoroughly with soap and also water to remove dirt and grime from the vehicle’s surface.

Rinse it off completely and then apply wax for a deep shine. Be wary of cheap brands, though: water spots can make your vehicle look dull.

 Why Do My Brakes Sound Rough After A Car Wash?

1. Moisture build-up

When you wash your car, much water can get trapped behind joints and gaskets. This leaves your car with excess moisture in places that can cause corrosion.

2. Brake fluid contamination

Sometimes water from rinsing and washing will leak into the brake system and mix with the brake fluid, causing it to become contaminated. This can happen easily when the reservoir cap is off or when you remove the reservoir.

3. Rust build-up

If you live in rainy areas, your brakes could sometimes get water and detergent. If you last washed your car a while ago, the rust builds up on your brake components, creating more friction.

4. Brake rotors

If you wrap your brake rotors or have brake pads you need to replace, it will cause extra friction on your brake components. This will create a noise when you apply the brakes.

5. Brake pads & Shoe wear

Worn-out brake pads or shoes can also contribute to this problem because they wear out quickly and don’t do their job like they’re supposed to.

This causes them to rub against the rotors, which can make a screeching sound when applied.

Why Do My Brakes Sound Bad After The Car Wash?

1. Water has entered the brake pads

When water makes its way into the brake pad, it can cause them to rust. The water will then corrode the metal components in the brake system.

In turn, the corrosion makes the brake pad much thinner and weaker, causing it to squeal when used. So, it is essential to completely dry out your brakes after washing your car.

2. Washed away brake dust

When washing your car, you will notice that some dust will get washed away. These dusts are made of small grains you should wipe or brush off before or during washing.

Sometimes, these particles become stuck and can cause your brakes to squeal. To eliminate this effect, you will want to ensure that the brakes are completely free from any materials which could cause them to squeal.

3. Brake fluid has been touched

When you clean your brake system, it’s recommended that you don’t touch the brake fluid reservoir. The brake fluid is usually threaded into the syringe, which can cause leakage if you don’t pay attention.

This could result in an ugly situation where your car has been in a nasty accident. You must protect the brake fluid and yourself to avoid any unfortunate accidents.

4. Brake pad is in bad condition

Many people mistake the squealing noise for the condition of the brake pads. However, when you use this method to check out your brake pads, it can cause harm to you and your car.

It is not recommended that you do this regularly as it can cause unnecessary damage. To properly check the braking pad, ask a professional mechanic to inspect your car’s braking pads.

Why Does My Car Run Better After The Car Wash?

Your car runs better after the car wash because the car wash’s high-pressure water hose blasts dirt and dust off the engine, which is what clogs filters.

The power washes also use a high-foaming soap penetrating deep into cracks, loosening stubborn grease and grime.

The increased airflow created by power washing also removes excess moisture from under the hood and prevents corrosion.

But these are benefits only you can enjoy. Because power washing can cause damage to your car’s paint and a lot of work when you’re trying to remove stubborn dirt.

It’s generally easier to use a car polish or wax on your vehicle than a power wash. The best method to get the dirt off your car is to use a damp cloth with gentle strokes to clean any area you need to clean, and the wax will give it a nice look.

Power washing is usually reserved for heavy-duty cleaning, vehicles parked outside in the dirt and grime, and those driving their cars through many dirty areas.

However, power washing is not an option if you boast an old car. This is because older paint jobs are too fragile to withstand power washing.

Is A Touchless Wash Safe For The STI?

Yes! The touchless wash is safe for STIs. The technology does not cause any scratches to the surface of the car.

In addition, it washes the car much more thoroughly than a traditional wash because water and soap are sprayed onto all sides of the vehicle at once, covering every inch of paint.

Even an inch or two under doors and into seams, which you can’t do with a hose. The touchless wash is also very gentle for the car.

A soft cloth will touch the car’s surface instead of hard water pressure from a hose which is heavier on the paint and can cause swirls and scratches.

It washes at much lower pressure than a traditional hose, so if you like to wash your car by hand, this is more comfortable for you. 

The touchless wash is useful to prevent micro scratches on the car’s surface. It works very well as a finishing wash, removing dirt and grime from the paint.

Combining washing, drying, buffing, and waxing in one cleans your car. I use this procedure daily, which helps keep my cars looking new longer since we are not drying or waxing every other day for surface dressing.

I have also found that you can wax less often using the touchless wash. To get the best results with this method, you should use a foam or microfiber towel to buff off dried soap residue from all paint surfaces.

What Is The Difference Between Safe Touch And Touch-Free?

FactorSafe TouchTouch-Free
PressureLow pressureHigh pressure
SafetyNo chemicalsAmmonia, power washing chemicals, and water.
Pump TechnologyPump with a rotating brush head that never touches the car’s surface.Pumps at high speed with bristles that come into contact with the paintwork.
Steam TechnologyNever uses steamUse steam for a short time to clean the car.
Sani-Dry drying systemDriers the car with a “wet wipe.”Uses air blowers to dry the car in a short period.
Dryer’s designDries the car only with warm air.Dries the car with a forced hot air machine.

What Are The Three Types Of Touch?

Soft TouchIt’s a Carwash that uses a cloth to clean the vehicle. The cloth is alternately water and detergent free and gentle to avoid scratches that may occur with the hard touch process.

Typically, all tools used in the soft touch process are cloth. Note: The soft-touch process is currently the most popular car wash method.
Touch-FreeThis Carwash process uses high-pressure water to remove unwanted grime from the vehicle. However, it uses an extremely low water flow to clean the vehicle gently.

This method does not use traditional squeegee, brushes, vacuums, or other methods. More, it does not include any physical touch to the vehicle.
HybridThis increasingly popular Carwash method combines traditional hand tools and touch-free equipment.

Typically, the touch-free equipment is used for flushing out all the loose debris – like dirt, bugs, small rocks, and large items that may have been picked up as the vehicle drove over a road.

After you flash the vehicle, it’s “washed” using traditional tools such as a brush to clean off anything left in hard-to-reach areas.

This is a good method for anyone who is on a budget or people who don’t have time to wait in line. It has both the benefits of a quick hand wash and modern touch-free technology.

Can A Car Wash Affect Brakes?

Yes! A car wash can affect your car’s brakes in the following ways:

1. Corrosion of brake pads

Water can enter the brake rotors or pads, causing them to corrode. This leads to the build-up of rust, which leads to some squeaking noise and brake problems.

2. Soil on brakes

The water that comes into contact with the brakes is usually a mixture of water and dust, which can lead to falling apart retaining clips, resulting in the inability to stop your car.

3. Water in brake lines

Wet brake lines cause abrasions of the lining and damage to the inside seals. This will lead to leaks later down the line, which will have you searching for another mechanic as soon as you are done visiting them.

4. Air pressure damage

Too much water in the brake lines causes an airlock where the fluid cannot move out, and because of this, the car will have a difficult time braking.

5. Brakes may fade

Too much water in the system from a car wash can lead to corrosion down the line, considerably weakening your brakes for the rest of your life.

How To Tell If Your Brakes Are Scrubbing?

1. Grinding noises

This is the most common noise that comes from a scrubbed brake system. It occurs due to wear and tear on the brake pads and discs.

This sound can worsen the longer you drive without changing your brake pads or rotors. When you hear this noise, stop by a reliable mechanic to have your brakes inspected.

2. Vibration

When your brake pads grab onto the rotor as they should, you may experience a vibration in the vehicle.

This is common when you first replace your brakes, and you can easily correct it by using the brake pedal more frequently, allowing each brake pad to wear in properly.

Over time, this noise gets worse and needs to be scheduled for an inspection.

3. Brake fluid smells burnt

If you abuse and neglect your car’s brake system, there may be corrosion and mineral deposits where the lines meet the master cylinder or master cylinder cover.

This causes some brake fluid to gas off. If this happens, it will have a burnt smell. You can get a mechanic to inspect your brake system and make the correct repairs.

4. Pulling to one side

This is normally related to the rotor or caliper that is attached to that rotor. If the rotor becomes too thick, it will rub against the caliper and cause a pulling sensation in that direction.

You can fix this problem by replacing your rotors or calipers respectively.


Hand washing is the most efficient and least expensive way to clean a car. However, you may prefer the touch-free wash because they need to get things done quickly or want their shopping bag protection while waiting.

As long as you’re comfortable with your decision, enjoy your wash.
