What is Cataclean and how does it work

Any car owner knows that one of the most important parts of keeping a car running smoothly is keeping the catalytic converter clean.

The catalytic converter is responsible for reducing emissions, and if it gets clogged, it can lead to decreased fuel efficiency and expensive repairs.

Cataclean is a catalytic converter cleaner that helps to extend the life of the catalytic converter and improve fuel efficiency.

Cataclean is easy to use and is compatible with all types of gasoline and diesel engines. Simply add it to your fuel tank every 3,000 miles or as needed, and it will help keep your catalytic converter clean and your car running smoothly.

Cataclean is a catalytic converter cleaner that was invented in late 1995. The idea for the product came about when the inventor, a chemist, noticed that the catalytic converters in his car were becoming clogged with soot.

He realized that if he could develop a product that would unclog the catalytic converters, it would improve the efficiency of the catalytic converters and extend their lifespan.

The first version of Cataclean was developed in 1997 and was sold commercially in 2000. Since then, Cataclean has become one of the leading catalytic converter cleaners on the market.

The company has continued to innovate and develop new products to meet the needs of its customers. Today, Cataclean offers a range of products that are designed to clean and protect catalytic converters.

Common Problems after using Cataclean

Common Problems after using Cataclean

Despite its popularity, some users have experienced problems after using Cataclean. 

White smoke from the exhaust

One of the most common problems that people experience after using Cataclean is white smoke coming from the exhaust.

This problem is usually caused by too much cleaner being used, which can lead to an over-cleaning of the catalytic converter.

Make sure you read the instructions carefully and only use the recommended amount of Cataclean in your fuel tank.

If you do experience this problem, it should go away on its own after a few miles of driving. If the problem persists, contact Cataclean customer service for assistance.

Damage to the catalytic converter

Catalytic converter cleaners, like Cataclean, are designed to remove deposits and build-up from the catalytic converter.

However, if used incorrectly, catalytic converter cleaners can cause damage to the catalytic converter.

One of the most common ways that catalytic converter cleaners can damage the catalytic converter is by excessive pressure.

When too much pressure is applied, it can cause the catalytic converter cleaner to push deposits and build-up into the catalytic converter, causing clogs and damage.

Additionally, catalytic converter cleaners can also chemically damage the catalytic converter if left on for too long or used in high concentrations.

As a result, it’s important to follow the directions on the catalytic converter cleaner bottle carefully to avoid damaging the catalytic converter.

Change the car’s exhaust sound

Another problem that some users experience after using Cataclean is a change in the car’s exhaust sound.

This is usually a result of the Cataclean burning off any deposits that have built up in the exhaust system and is, therefore, nothing to worry about.

However, if the sound change is dramatic or persistent, it may be worth taking the car to a mechanic to have it checked out.

What are the solutions to problems after using Cataclean?

What are the solutions

Fortunately, there are some solutions to these problems. If you’re experiencing any of these issues after using Cataclean, we recommend that you try one of the following solutions.

Solution 1: Make sure you have 1/3 fuel in your tank

Left 1/3 fuel in your gas tank before pouring in Cataclean. This will make the cleaning process more effective and help to prevent over-cleaning of the catalytic converter. Don’t pour in a full tank because it will over-dilute the Cataclean and make it less effective.

Solution 2: Use the right amount of Cataclean

Make sure you use the correct amount of Cataclean. Using too much Cataclean can lead to problems, such as white smoke from the exhaust or damage to the catalytic converter.

Check the instructions on the Cataclean bottle to ensure you’re using the correct amount for your vehicle.

Solution 3: Follow the directions carefully

Be sure to follow the directions on the catalytic converter cleaner bottle carefully. This will help to prevent any damage to the catalytic converter and ensure that the cleaning process is done correctly.

Catalytic converter cleaners are designed to clean the catalytic converter, but if used incorrectly, they can cause damage. Be sure to follow the directions carefully to avoid any problems.

Solution 4: Drive for 30 minutes after pouring Cataclean

After pouring Cataclean into your gas tank, be sure to drive for at least 30 minutes. This will allow the Cataclean to work its way through the catalytic converter and start cleaning it.

If you don’t drive for at least 30 minutes, the Cataclean may not be as effective and you may not see the full benefits.
