When it comes to home repairs, a rusted screw can be one of the most frustrating problems to deal with. Rusted screws can make it difficult to properly secure fixtures and, if left unaddressed, can lead to bigger issues down the line.
This is especially true regarding toilet bases, where a secure connection is crucial for proper functionality. So how to remove rusted screws from toilet base?
Throughout this article, we will go over different ways to remove rusted screws from your toilet to get your bathroom back in working order.
Methods On How to Remove Rusted Screws from Toilet Base
Preparation
Before diving into the various methods for removing rusted screws, it is important to take some necessary precautions to ensure safety and efficiency. Here are some things to keep in mind before getting started:
Gather the necessary tools: Depending on your chosen method, you may need different tools. Here are some tools that you may need: pliers, a screwdriver, an adjustable wrench, a power drill, an impact driver, a hacksaw, a rotary tool, a liquid rust remover, vinegar or lemon juice, a blow dryer, and heat gun.
Wear protective gear: When dealing with rusted screws, it is important to wear gloves and eye protection to prevent injury.
Turn off the water supply: To avoid water damage, turn off the water supply to the toilet before beginning any repairs.
Method 01: Soaking the Screws
One of the easiest and most common methods for removing rusted screws from a toilet base is soaking them in a liquid rust remover. Here’s how to do it:
Apply the rust remover: Apply a generous amount of liquid rust remover to the rusted screws. Make sure that the liquid covers the screws completely.
Let it sit: You might need to soak the screws for several hours or even overnight. Check the rust remover’s instructions for the recommended duration.
Remove the screws: Once the screws have soaked long enough, use pliers or a screwdriver to remove them. They should come out with ease.
If you don’t have a liquid rust remover on hand, an alternative method is to use vinegar or lemon juice. The acid in these substances can help break down the rust. Here’s how to do it:
Apply the vinegar or lemon juice: Apply a liberal amount of vinegar or lemon juice to the rusted screws. Make sure that the substance covers the entire surface of the screws.
Let it sit: Depending on the level of rust, you may need to let the screws soak for several hours or even overnight.
Remove the screws: Use pliers or a screwdriver to remove the screws after they soak. You should be able to get them out easily.
Method 02: Using a Screwdriver
If soaking the rusted toilet tank bolts or screws does not work, you can try using a screwdriver to remove the rusted screws. Here’s how to do it:
Choose the right screwdriver: Make sure you are using the right size and type of screwdriver for the job. If the screwdriver is too small or too big, you risk damaging the screw or the toilet base. Also, choose a screwdriver with a good grip to ensure you can apply enough pressure.
Apply pressure: Using one hand to hold the screwdriver in place, apply pressure to the screw or bolt with your other hand. Slowly turn the flathead screwdriver counterclockwise to loosen the screw.
Use an impact driver or power drill: If the screw is still stubborn, try using an impact driver or power drill with a screwdriver attachment. This will provide more torque and make it easier to loosen the screw. Use a low speed and start with gentle pressure because too much force will cause the screw to break.
Remove the screw: Once the screw is loose, pull it out with pliers or a screwdriver. If the screw is still stuck, try applying more rust remover or vinegar and repeating the process.
Method 03: Cutting the Screw
If the rusted toilet seat bolt or screw is completely stuck and cannot be removed by soaking or using a screwdriver, cutting the screw may be the only option. Here’s how to do it:
Choose the right tool: You can use a hacksaw, rotary tool, or reciprocating saw with a metal cutting blade to cut through the screw. Make sure to choose a tool with a blade that is suitable for cutting metal.
Cut the screw: Carefully cut through the screw at a 90-degree angle, ensuring not to damage the toilet base. Take your time and apply gentle pressure, as too much force can cause the saw blade to slip.
Remove the screw: Once the toilet base or toilet tank bolt or screw has been cut, use pliers to remove the remaining piece from the toilet base. You may need to repeat this process for any remaining rusted screws.
Method 04: Heating the Screw
Another method for removing rusted screws is to heat them up. This can help break down the rust and make it easier to remove the screw. Here’s how to do it:
Apply heat: Use a blow dryer or heat gun to apply heat to the rusted screw for several minutes. Be careful not to overheat the area, damaging the toilet base.
Remove the screw: Once the screw is hot, use pliers or a screwdriver to remove it from the toilet base. If the screw is still stuck, repeat the heating process and try again.

Why Do Toilet Anchor Bolts Rust?
The primary reason toilet anchor bolts rust is the presence of moisture around the base of the toilet. This moisture can come from various sources, including leaks from the toilet tank or bowl, condensation on the toilet surface, or poor drainage in the bathroom.
When moisture is present, it can react with the metal of the anchor bolts, causing them to rust and corrode over time. This can weaken the brass bolts, making them more prone to breakage or failure.
Another factor that can contribute to rusting of toilet anchor bolts is exposure to certain chemicals or cleaning agents. Harsh chemicals like bleach or ammonia can corrode metal surfaces, including anchor bolts.
How Can You Tell If a Screw Is Rusted in A Toilet Base?
If you suspect that the screws holding your toilet base are rusted, there are a few signs that you can look out for. One of the most noticeable indicators is a reddish or brownish discoloration on the surface of the screw.
This discoloration results from oxidation when metal is exposed to moisture and air over time. In addition to discoloration, rusted screws may appear corroded or pitted, with a rough or uneven surface.
To look closer at the screws, you may need to remove the toilet from its base. If you notice that the screws are difficult to turn or appear stuck in place, this could also be a sign that they are rusted. In extreme cases, the screws may even break or snap off when you try to remove them.
If you do find that the screws are rusted, it’s important to replace them as soon as possible. Rust can weaken the structural integrity of the screws, making them more likely to break or fail over time. This can lead to leaks, instability, and other problems with your toilet.
How Can You Keep Your Toilet Base Screws from Rusting?
You can take a few simple steps to prevent rust on your toilet base screws.
Firstly, it’s essential to keep your toilet area clean and dry. Moisture and dirt can lead to rusting and corrosion, so regularly cleaning your toilet base and surrounding area can help prevent this. Use a mild cleaner and a soft cloth to wipe down the base, and dry it thoroughly with a towel.
Another effective method is to apply a rust inhibitor to the screws. This can be purchased from most hardware stores and applied with a brush or spray. Apply the inhibitor evenly and allow it to dry before using the toilet.
If you have noticed rust on the screws, you can use a rust remover or a wire brush to clean it off. Afterward, apply a rust inhibitor to prevent any further rusting.
Finally, consider replacing your toilet base screws with stainless steel screws. Stainless steel is resistant to rust and corrosion, making it a great alternative to traditional steel screws.
Conclusion
Dealing with rusted screws on a toilet base can be a frustrating experience, but there are several methods you can try to remove them. Different methods may be more effective depending on the level of rust and the available tools.
Following the steps outlined in this article and taking necessary safety precautions, you can successfully remove rusted screws and restore the functionality of your bathroom once again.
