How to Remove Excess Sludge and Clean a Heating Oil Tank

According to a company providing fuel oil delivery in Washington Township, sludge, commonly referred to as thick, gel-like silt, builds up over time in heating oil tanks. You might find yourself trying to figure out what to do every few years as the sludge starts to grow. Is it a significant issue? Should you clean it? Is it so awful that you need to replace your tank?

Avoid allowing heating oil sludge to stress you out this winter. Be proactive by cleaning your tank or hiring a specialist to remove the gunk from your possession. The sediment, also known as heating oil sludge, collects at the bottom of your oil tank over time and is a dark, sticky substance.

It comprises dust and debris, extra moisture, flaky rust from the tank’s inside, oil-eating microbes, and other fuel byproducts. When petroleum is kept in storage for a long time, especially in a mostly empty tank, sludge typically accumulates.

As soon as it’s finally time to crank up the heat in the Northeast, many homeowners who find sludge in their oil tanks do it in the middle or early months of the year. Once they come for your yearly fill-up, a gasoline delivery technician can be the first to discover the accumulation of silt in your tank.

How Does the Sludge Accumulate?

The remaining petroleum gradually exposes to air, light, heat, and other reactive components. The catalytic event is air and moisture getting into your fuel tank and gasoline supply. Your fuel tank features a vent pipe that allows air to enter and exit since it’s essential for maintaining the pressure equilibrium in the tank. This pipe allows air to escape during oil deliveries.

Air enters the vent to replenish the oil as it expels through the fuel line. The air from outside contains moisture. As the temperature changes once it is inside the tank, it condenses and turns to rust. Rust and water condensation eventually settle on the tank’s bottom. Even if this didn’t lead to sludge, the water still creates issues.

Pooled water can cause the tank to rust and corrode within, leading to oil leaks. Microbes are also grown there. Oil floats above the water, and the interface between the two liquids offers the ideal habitat for these bacteria. Your oil supply is being broken down into sludge by bacteria.

These substances interact chemically with the oil, causing the molecules to expand and eventually become thick and dense. Then, they adhere to the storage tank’s floor. In exceptionally harsh winters or when the oil tank is low, sludge is more frequent.

How to Clean Your Heating Oil Tank?

Your oil tank will very indeed contain sediment. The average homeowner must clean their oil tanks every three years, though they may be able to extend this to five. People who routinely refuel their tanks with fuel oil delivery in Washington Township must clean the tank more frequently.

You should also consider cleaning your vent cap immediately if you recently encountered a loose vent cap, which could have allowed insects, air, or moisture into your tank. Your expert can provide you with a more detailed cleaning program based on your regular usage.

Be prepared to get dirty if you decide to clean the oil tank’s muck on your own rather than hiring a pro. Gloves and clothing that you don’t mind getting grease on are better. To start cleaning, you’ll also need some supplies:

  • Disposable containers or plastic buckets
  • Cleaning rags
  • An air hose
  • A portable air pump
  • A water hose
  • Trisodium phosphate (TSP) cleaner
  • Denatured alcohol
  1. Drain the Oil Tank

You must first empty the tank of all the oil and dislodge the muck inside, and don’t take a fuel oil delivery in Washington Township at that time. Open the cap on one of the disposable containers, place it under the drain valve, and wait until all the oil drains. To prevent spills, tightly fasten the lid and gently move the containers out of the way.

Put another container behind the valve and nest it. Spray some fresh water into the tank with your hose. Spray continuously until the water coming from the valve is clear. Replace the valve cap after moving this second container out of the way.

  1. Scrub the Excess Sludge

According to a petroleum company providing fuel oil delivery in Washington Township, Use your cleaning rags to remove any tenacious gunk and sludge from the area around the drain after all the water has been removed. While you’re doing it, wipe the oil tank outside with cloths.

Although leaves and caked-on dirt or grime don’t add to sediment building, it is always a good idea to remove them from the outside of the tank. Apply some rustproof paint after cleaning any visible rust from the exterior.

  1. Add Cleaner

Now you can delegate labor-intensive tasks to your cleaner. Since trisodium phosphate is tough on grease, filth, and soot and is ideal for heavy-duty cleaning applications, it is frequently suggested as a cleaner for oil tanks. TSP is a dry, white powder that needs to be diluted with water.

You may need to use a different chemical. Phosphate-containing cleansers are prohibited in many states. Avoid TSP to safeguard your lawn and garden plants.

If so, choose a TSP substitute as a phosphate-free solution for the well-liked degreaser. Search for a different cleaning product explicitly sold for cleaning oil tanks. Avoid mixing up an oil additive to avoid silt buildup with an oil tank cleaning.

  1. Dry the Tank and Refill the Oil

You must drain the extra water after cleaning your tank with a sprayer. Water can rust out your tank from the inside and is what initially causes sludge accumulation. The denatured alcohol is used since you’ll need to do more than just air out the tank.

Pour roughly 3 gallons in, and splash it around from various angles to thoroughly coat the interior walls of the tank. Alcohol is quite effective at removing extra moisture from your tank. After adding it, reinstall your air hose and turn on the pump. After an hour, when all the water has evaporated, leave it.

When your tank is empty, replenish it with fresh oil. You should not remove the oil you evacuate from the tank because the bacteria that fed on the oil and generated your sludge has already infected it. To obtain a new supply, place an order with your oil supplier.

  1. Dispose of the Sludge Safely

You only have a few containers of most of the sludge, diluted TSP, dirty oil, and dirt. These containers technically hold hazardous waste, and even when sealed, they can’t precisely be left in your garage.

Get in touch with your state’s hazardous waste disposal agency or environmental protection authority for information on properly disposing of your oil tank sludge.

Why Should You Be Worried About Heating Oil Sludge?

You may consider removing all that sediment after knowing what goes into cleaning an oil tank. What’s the big deal? On the one hand, oil tank sludge may not be a cause for concern.

Microbes, rust, and other contaminants you would not want to be around are present. However, it remains attached to the bottom and won’t enter your system when submerged in a full oil tank. The underlying issue becomes apparent as your oil level drops, which could harm your heating system.

The Final Words

Sludge is more prone to get drawn into and clog your supply line when there is little oil in the tank. Additionally, it could stop the oil filter, preventing all or part of your oil from getting into your heating system. Your system’s efficiency is hampered by the blocked oil filter, which uses more gasoline than is necessary. This post will teach you to remove sludge and much more about it, which will help you manage heating oil furnaces and safeguard your system.
