How To Use Lacquer Thinner Catalytic Converter Cleaner? (4-Easy Steps)

Catalytic converters are critical equipment for turning pollutants in a car engine into harmless exhaust fumes. It requires cleaning with chemical process engineering chemicals such as lacquer thinner. However, utilizing lacquer thinner as just cleaning for this gadget is inconvenient. This post will teach you how to use lacquer thinner catalytic converter cleaner safely and quickly.

The excellent news is that using lacquer thinner cleaning isn’t as difficult as you would believe. So, without wasting precious time, let’s dive right into it and start with the topic.

Lacquer Thinner Catalytic Converter Cleaner

To begin cleaning the catalytic converter, fill a gas tank to the halfway mark and then pour some pure lacquer thinner. After that, embark on a long trip. You’ll want to go at incredible speeds for roughly 140 miles.

If you desire to complete it yourself rather than hiring another person, operate the engine at 2300 RPMs for approximately 30 minutes. This will aid in removing carbon residue that may have accumulated on the converter.

So, what is a lacquer thinner catalytic converter cleaner?

It is a chemical liquid that has the potential to destroy a catalytic converter inside a combustion engine.

This cleaner’s fundamental ingredients include butyl acetate, acetone, and other soluble chemical compounds. Liquid lacquer covering and plastic are examples of dissolvents. So, a lacquer thinner cleaner may clean catalytic converters like numerous different cleaner kinds.

The use of lacquer thinner catalytic converter cleaner, on the other hand, is debatable. Maybe it is not well-known or dependable.

If you understand how to use a lacquer thinner effectively and safely, it can substitute other cleaners for cleaning this automobile gadget. Keeping a vehicle’s internal combustion catalytic converter in good working order increases its effectiveness.

Why is lacquer thinner suitable for the cleaning of catalytic converters?

Lacquer thinners are highly effective in cleansing catalytic converters since it dissolves accumulated carbon deposits inside the engine. Getting rid of the carbon residue is crucial because it improves engine performance and reduces emissions.

Emissions should constantly be maintained to a low level to safeguard the environment. Cleaning the engine improves its performance and increases fuel efficiency and pollution. So, why not use a lacquer thinner catalytic converter cleaner?

Why you need a clean catalytic converter:

The catalytic converter’s cleanliness is critical because it makes your engine run more efficiently. When the machine’s insides become clogged, the engine will run less effectively, resulting in decreased fuel efficiency and pollutants. This is harmful to the environment and awful for your cash.

How to use lacquer thinner catalytic converter cleaner (Step-by-step Solution):

A converter is essential in catalyzing hazardous substances from the internal combustion engine into the toxic-free exhaust. During its operation, this gadget effortlessly catches dust particles or stains. So, it would help if you gently cleansed it using specialized cleaning.

Step 1:

Before cleaning the catalytic converter with a gallon of lacquer thinner, you must first inspect it. Several aberrant indications in your car show this device’s poor performance. The catalytic converter is clogged by dust or a large number of particles. This wretched condition might obstruct the converting of hazardous contaminants, preventing the gadget from functioning correctly.

Step 2:

After inspecting the item, you may clean it with lacquer thinner. Even if you don’t have any functioning equipment or mechanical engineering skills, this is the most straightforward approach to fixing the catalytic converter without having to remove it.

Step 3:

In Lacquer Thinner Catalytic Converter Cleaner, carefully read the documentation and understand how to use the cleaner, you may pour this directly into the gasoline tank. This stage determines whether or not it may clean the catalytic converter. However, it is not a simple task. As an instruction, pouring lacquer thinner cleaning into the tank must be proceeded by a permissive proportion.

The lacquer cleaner might damage your car’s exhaust pipe and other engine components if you choose the wrong path. The chemical engineering procedure is mainly used in the manufacturing of lacquer thinner. Consequently, if the solvent quantity is incorrect, it severely erodes vehicle parts.

Step 4:

The pouring of lacquer thinner is complete. You may begin driving your automobile at various speeds. At first, your car can run at a rate of 1500 – 2000 RPMs and activate the catalytic converter. You gradually increase your speed from 2500 to over 3000 RPMs for 150-200 miles to get the catalytic converter warm enough.

Its temperature increase will burn off the blocked components and contaminants contained within this equipment. However, if the industrial gases are still in the tank, this burning process has the potential to ignite them. Hopefully, this will help you understand how to use a lacquer thinner catalytic converter cleaner.

Frequently Asked Questions

Can you clean a catalytic converter using acetone?

Acetone is quite harsh on engine seals. So, the seals will be alright if you burn this out quickly enough. As previously indicated, if the EGT reaches a temperature that the catalytic converters cannot tolerate, they would physically melt. However, this isn’t a big deal when they are already congested.

Can you use thinners to clean the oxygen sensor?

Certainly not. Lacquer thinner compositions vary by brand and may include acetone or other compounds that are detrimental to the fuel system, mainly rubber and plastic parts.

Can a clogged catalytic converter be cleaned?

Pouring a cleanser into the gas tank is a simple way to do a routine cleaning on a catalytic converter. An over-the-counter cleaning, such as Cataclean or even lacquer thinner, can do the trick. Sometimes a thorough cleaning is required, necessitating the gadget’s removal.


Lacquer thinner catalytic converter cleaners may even be called crucial for car maintenance. You can extend the lifespan of the car and avoid pricy repairs by making an effort to cleanse the catalytic converter.

This post should have addressed some of your queries regarding catalytic converters cleaners. If you have further questions, don’t hesitate to contact a skilled technician. We hope this article serves as a one-stop solution for all your queries.
