By: | January 12th, 2023

Manways are a critical component of many industrial systems, like breweries, energy plants, wastewater treatment, and food production. They provide access to tanks and vessels, making it possible to inspect and clean inside components. Keeping these components clean and in good working order can not only extend their lifespan but also help prevent costly repairs and breakdowns.

To maintain your manways in optimal condition, you must clean and manage them often. This blog will discuss the best tips and tricks for maintaining and cleaning manways.

Ways to Maintain your Manways

While they may seem relatively simple in design and construction, Manways still require regular maintenance to ensure optimal performance. From cleaning and lubricating the components to inspecting for signs of wear and tear, we will provide the key steps you need to keep your manways running smoothly. 

Identifying potential problems

Regular inspection of stainless steel manways can help identify potential problems before they become too serious. Look for any signs of corrosion or pitting on the surface. Check for loose mounting hardware or signs of leakage around the seals and gaskets. You should do these inspections regularly and address any problems immediately.

Checking mounting hardware 

The hardware that holds stainless steel manways in place should be checked periodically to ensure that it is secure. Loose fasteners can cause leaks and damage the manway. Always check the mounting hardware is in good condition and tightened properly.

Checking seals and gaskets

Seals and gaskets are a critical part of manways and must be checked regularly for any signs of wear and tear. If a seal is cracked or worn out, it may need replacement. It is also essential to check for any signs of leaking. You should fix a leak as soon as you find it.

Cleaning the manway 

Manways should be cleaned regularly to ensure that they are in optimal condition. Several types of cleaning solutions and tools are available for cleaning them. 


It is vital to choose the right tools and options for the job and guarantee they are disposed of responsibly when finished. The section below will highlight simple tips to clean your manways properly.

Quick Manway Cleaning Guide

The most common methods for cleaning your stainless steel manways are steam cleaning, chemical cleaning, and pressure washing. Which technique you should use will depend on the material, the contamination level, and the manway’s size. 

Choose the right cleaning solutions

Depending on the type of stain, various cleaning solutions are available:

  • For grease and oil stains, degreasing solutions are used. 
  • For dirt and dust, mild detergents are suitable. 

It is crucial to select the proper cleaning agent for the material of the manway cover, as using the wrong type of cleaner could cause damage or discoloration. Additionally, you must use a safe solution for the environment that doesn’t contain harmful chemicals. 

Select the right tools

You will also need the proper tools for the job. This includes a sponge or cloth for scrubbing, gloves for protection, a bucket for the cleaning solution, and a brush or scrubber for hard-to-reach areas. Depending on the type of material, you may need a power washer or sandblaster for tough, caked-on dirt and grime.

Dispose of the Cleaning Supplies Properly

Proper disposal of cleaning supplies is also important. Make sure to dispose of all cleaning solutions and tools following local regulations. Never pour them down the drain or into waterways.

Final Words

To ensure manways’ proper safety and function, it is essential to adhere to regular maintenance and cleaning practices. You should conduct routine visual inspections and replace any damaged or corroded components. Additionally, it is necessary to clean and lubricate them periodically to prevent any debris and dirt build-up. By following these simple maintenance and cleaning tips, manways can be kept in top condition.
