Flushes Buying Guide

The biggest takeaway of using an engine flush is that any dirt, dust, soiling materials, and other contaminants that can influence the engine's output will be washed out over time. Generally speaking, engine flushes are usually very safe to use and can almost immediately boost engine efficiency.

What all does it do?

It cleans cooling systems to help prevent overheating, which is usually a common reason for engine failure. Removing any oily sludge or toxic fuel remains, thereby restoring the heat in your cabin. It also effectively removes fatty deposits such as grease, dirt, sludge, grime, and metal shavings by drawing metal oxides into the solution. It does so with detergents that gently clean and suspend any sludge deposits, which clears out the oil passages that were previously restricted, thereby improving the entire oil flow system.

How strong is it?

It is strong enough to regain the maximum cooling system efficiency. With a 2-in-1 formula designed for light flushing and heavy-duty cleaning, it dissolves corrosion and removes grease. But it mostly doesn't have solvents that are harmful and is non-toxic and non-acidic, therefore easy-to-use and safe for all cooling system metals.

Cleans and dries rapidly

Its valve control technology lets you control the spraying amount of liquid, which can be done to make cleaning much faster yet intensive. That means it won't leave any soap residue behind either, as the drying process is very quick, thereby reducing the chances of contamination. Due to its strong body and high-quality rubber tubes, it'll easily last a long while unless tampered with.

A wide array of applications

It comes with a stiff nylon brush, perfectly designed to clean surfaces and a deep-down clean for all nooks and crevices. Powered by a high-speed spinner motor, it penetrates deep and dramatically speeds up cleaning time for tight spots and areas for a powerful clean. It's safe for engines run on diesel, hoses, coolants, and plastics of a similar kind.
