Many people end up giving up on this job, thinking that it’s just too difficult. The good news is that there is an easy way to remove these bolts without any damage. Here, we will show you how to do it in just a few steps!

How to Remove Rusted Toilet Flange Bolts

Why Do Toilet Anchor Bolts Rust?

Rust is a natural reaction to the metal in contact with saltwater, which is why toilet Flange bolts rust. Water rushes down the pipe and into the tank when a toilet is flushed. Due to the presence of water, there can be moisture which causes the flange in the bowl to rust.

Flange bolts are usually made of zinc or iron and are easy to rust on these surfaces. If you see rust on your toilet flange bolts, it is important to take action before it causes more damage.

The condensation of the bolts in your tank and exposure to water has created rust over the years. This is the result of rust oxidation, which results from iron, steel, or other metals coming in contact with water and oxygen over time.

Methods to Remove Rusted Toilet Flange Bolts

If you are experiencing trouble removing rusted toilet flange bolts, a few methods may work for you. We gonna start discussing methods in detail below: Let’s see how to proceed with removing rusted flange bolts.

1. Use a Plier or Wrench 

Here is an instant solution for removing rusted toilet flange bolts. This application may use for the initial stage if rust isn’t bad too much. First, you can try using a simple plier or wrench as a basic and first method.

2. Use a WD-40 and Wrench or Pliers

This is a more involved approach but can be successful if there is a lot of rust and the bolts are relatively accessible. The WD-40 will loosen the rust of the flange, allowing you to grab the bolt with a wrench or pliers. This process will definitely work if the condition of the bolts is not too bad.

3. Use a Dremel

Dremel can be an excellent solution for the bold removal of rusty flanges. With this, you can try two ways. First, you can cut the rust around the bolt with Dremel, then try to open it by turning the bolt with a wrench or pliers. Second, if the first technique does not work, cut the bolt with Dremel; Then, you can remove it from the screw easily.

You can also cut the steel part of the flange next to the bolts. This process will separate the bolt of the flags, and you will get a little more space.

4. Use a Mini-Hacksaw 

Use this method to cut the bolt of the flush with the flange. This task can be a little difficult or time-consuming. Mini-hacksaw blades must be new and sharp to make the job easier.

The mini-hacksaw blade should start cutting from the base under the bolt. It is not possible to reach the bolt with the mini-hacksaw blade flange in some cases. Because the flange is a few centimeters below the floor, the process may not work as expected. 

5. Use an Angle Grinder

I think it’s a much easier and faster method. You can easily cut from the bottom of the bolt by turning on the Angle Grinder. You can then pull the fan out with a screwdriver or pliers.

N.B. This is the most drastic option and should only be used if all other measures have failed. Angle grinders are dangerous tools and require careful use, so read up on how to safely operate one before attempting this method.

6. Use a Socket Wrench 

If you have a socket wrench, you can try to open it. If the socket wrench can fit properly with the bolt, the socket wrench will hold the flange bolt tightly, and the flange bolt will open as soon as the wrench is rotated. 

Many people make that mistake- Before opening with a wrench, do not oil the middle of the bolt but you can apply rust remover.. This will cause the bolt to slip around, and the socket wrench will not be able to hold the bolt tightly.

7. Flat Sanding Stick With Vise-grip or Wrench or Pliers

You can rub it around the bolt with a flat sanding stick to grip it. This will separate the rust from the bolts, and the core of the vault will come out, which you can open with either Vise-Grip, Wrench, or Pliers.

8. Drill Out Bolts

If you have a drill with bits in multiple sizes, it may be possible to drill out rusted bolts without damaging results. However, make sure your tools are correctly applied.

Once you have removed the rusted flange bolt with one of these methods, all you have to do is lift the toilet up and close its flange. You can then replace or repair the plumbing fixtures as needed.

2. Repaint

Coating can be used to limit rust spread. After the rust is removed from a specific area of ​​the metal material, painting on that surface can help protect the metal from environmental influences, such as moisture, which causes rust. 

3. Rust Cleaner

There are numerous rust cleaner brands. Most of them contain a dissolving agent, such as oxalic acid, which chemically reacts with iron oxide to remove it from the base material.

These rust cleaners are especially suitable for small metal parts, such as fasteners, which can be dipped, soaked, or sprayed in a solution to remove rust. The manufacturer’s safety recommendations should be taken seriously, as misuse of these cleaners can be harmful.

Are There Any Risks Involved in Attempting to Remove Them?

While there are no guarantees, using a safe method should minimize potential risks. If you choose to use an oil-filled wrench, wear an eye protector and gloves.

If you need to use a hacksaw, avoid cutting through your plumbing or injuring yourself. Finally, if you decide to use an axle splicer, make sure that you understand how it works and how to safely operate it before attempting the job.
