How to Remove Rusted Toilet Tank Bolts? [Explained]

How to Remove Rusted Toilet Tank Bolts?

Removing rust from bolts is an annoying task that can be difficult to do. Rather than fighting with it yourself, there are a few items you might have in your house that will make the job easier and much quicker.

Removing rusted toilet tank bolts may seem like a daunting endeavor but if you use these simple tips anyone should be able to complete this project without too many difficulties. First of all, purchase some ice cubes or put regular old water into Ziploc bags so they’ll stay cold – not just for consumption purposes either: take one bag out at a time as needed during the process (put them back in after each use). Make sure when removing any screws on the bolt head itself NOT TO USE ANY METAL SCRE.

The following guide will teach you how to remove rusted toilet tank bolts by first soaking them in vinegar overnight, next to heating them up with an electric stovetop or oven, and finally sanding down the bolt head to make it smooth again. Follow these steps closely and soon enough that pesky bolt will be out of your way.


How to Remove Rusted Toilet Tank Bolts?

1- Get a bucket

One of the oldest tricks in plumbing is to use a bucket or container to catch rust particles and water when removing rusted toilet tank bolts. This prevents damaging your hands by touching the cold metal, hurting them with pliers, or getting rusty slivers under fingernails from grabbing it too hard!

2- Put on Your Gloves and Safety Goggles

Cover your hands, eyes, and any exposed skin in order to avoid rust from getting into open wounds. When you remove the bolts there’s a good chance they will be stuck inside of holes which means that turning them with pliers may not work. Use an electric drill with a metal cutting blade instead as this is less likely to damage what remains intact on the toilet tank while also reducing how much force needs to go through it when removing tight bolts or screws around edges and corners where penetrating power isn’t strong enough for regular tools.

3- Fill the Container with Hot Water

You are now ready to remove the bolts from your toilet tank. Fill a bucket with hot water and pour it into your toilet’s cistern until there is enough room for you inside of the hole in order to reach those pesky rusted-tight bolts. Let this process play out for several minutes (or hours) while trying not to flush so that all of that lukewarm, rusty liquid stays where it need to be.

4- Wear Protective Eyewear and Rubber Gloves

If you want to avoid getting an eye injury or a cut on your hand, enter the tank with protective eyewear and rubber gloves. To prevent future rusting of bolts that will need work in the near future, it is important to use these precautions now when removing rusted toilet tank bolts so as not to be disappointed later.

5- Use a Wrench

Get in and under the toilet to loosen bolts with a wrench. Remove all rusty bolts from below the rim of the bottom of the bowl for new installation. (don’t forget about those at the bottom!)

6- Use Pliers

Once loosened, use pliers to remove them one by one – be careful not to scratch anything in your house! If you have trouble removing them yourself, enlist someone else’s help or buy a tool designed specifically for this purpose.

7- Wrap Up

Clean up after yourself – don’t leave tools lying around where they can cause an accident later on! Remember that if any rust particles got into your home while you were working on this project, clean those areas too so that nobody gets hurt when walking through them! You may also want to consider replacing old bolts with new ones for added security.

How to Replace Toilet Tank Bolts?

1. Find the toilet tank bolts

A toilet tank is the part of a flush toilet that holds water and supplies it to fill for flushing. The bolts on this type of device may become loose over time, leading to leaks or other damage from vibrations in the home or facility. If you find your own bolts are not working well enough, replace them with new ones before they stop holding your plumbing together.

If you have any questions about how best to maintain these devices contact an expert like us at Plumber Services Incorporated today so we can get those parts replaced before they cause even more problems down the line.

2. Remove old bolts with a wrench and replace them with new ones

After removing the old bolts, you will need to install new ones. The process is easy and efficient with a simple hand tool kit that includes all of your needs!

3. Make sure the new bolts are tightly tightened so that they don’t loosen

You should always check your bolts to make sure they’re tightened. Bolts that loosen can cause serious safety hazards and are hard to fix if you wait too long. You’ll want to have a tight grip on the bolt so it doesn’t fall out, otherwise, there’s no point in tightening them!

4. Turn on the water supply and flush the toilet to test for leaks or other problems

Make sure to turn on the water supply for a few seconds before testing your toilet. Flush it and listen carefully – if you hear any hissing or other noises, that’s an indication of potential problems!

5. Clean up any tools you used in case of corrosion or rusting, then put everything back where it belongs

It’s important to clean up after a project. This will protect your tools from corrosion or rusting, and also save you the hassle of having to find something in an unfamiliar garage later on.

6- Test your work by flushing again, watching for any signs of leakage

Test your work by flushing again, watching for any signs of leakage and toilet overflow. It is important to test the output of your fix. Flush first to make sure you didn’t cause a blockage. If that goes well then watch for leaking water or running over from another fixture in the bathroom such as the sink faucet or bathtub spigot.


We’ve provided you with a few methods for removing rusted toilet tank bolts. Hopefully, one of them will work for your situation and save you the headache that comes along with trying to remove stubborn rusted bolts by yourself.
