How to remove old silicone caulk

If you have a ceramic tile with silicon residue, removing it is easy. Anyone can remove old silicone caulk from the tile with the sealant removers underneath. Usually, you should consider using a razor blade or any other sharp scraper that can remove this material, along with Goo Gone. But you should always be careful when working with such a tool. Move slowly and take your time, as patience is key, and there is no rush.

After scraping the silicone with the blade, some residue might still be left on the tile’s surface. If that happens, using a mix of silica sand and water will create a substance abrasive enough to remove the leftover. Before you apply this method to the entire working area, you should do it on a small one to be sure it is effective.

Some types of tile, such as ceramic or porcelain, are strong enough to withstand the rough process of silicone removal. Other types, such as stone, could be easily damaged. You have to be more careful with this operation.

What dissolves it?

To dissolve silicone, you will need to apply a softening agent. It is the most effective solution for softening silicone, which you can remove using your hands or any tool that could help you. You can use many substances for this purpose, but the most affordable ones are vinegar and alcohol.

These solutions can be found in your kitchen and are effective for this purpose. If you have WD-40, you can also use that and get the same results. But if they are not fit for your job, you should look to get something stronger than isopropyl alcohol.

Be advised that you must contact a professional to obtain such a chemical. But regardless of the substance that you use, all you have to do is apply a small amount to the areas covered in silicone. After several hours, the silicone will soften and be safely removed. 

Softening caulk

Softening the caulk before removal is necessary. Otherwise, you will struggle a lot with this process. For this procedure, you will need isopropyl alcohol which is also safe to use for painted and plastic surfaces. All you have to do is soak a piece of material in the alcohol and place it on the surface with the caulk for a couple of minutes.

During this time, the substance will soften the caulk and make removing it much easier. It causes the caulk to expand, but be advised that this works only with water-based caulk. If you are dealing with 100% silicone, alcohol might not be enough to soften this material.

But you can still try and remove it after it’s soaked. As the caulk expands, you will notice how easy it is to scrape it off. Repeat this process as often as needed, and patience is important. Do not rush this operation, as you might damage the surface itself. 

Removing residue

After you followed the advice from the previous section and soaked the caulk in alcohol, you can now continue with the process. It is much easier than you think. While normally it is difficult to scrape this hardened material, you can do it effortlessly as the alcohol caused the caulk to expand.

Any blade will do, but it is important to operate it safely. There is the risk of damaging the surface or cutting yourself, so you should take all the necessary precautions before starting this process. You can also use a scrub pad to minimize the risk of injury. 

If it is difficult to remove the caulk in some areas, apply any solvent that will further soften the silicone residue. Repeat this process until you can remove all the caulk from the working surface, but it is crucial not to rush it. 

Getting it off your hands

After you have finished the process, you might have silicone left over on your hands. This situation could be avoided if you used gloves and other protective equipment. Still, there are several ways in which you can remove this material from your hands.

You can try acetone, a great solution for removing silicone from your hands. It is an organic chemical used in cosmetics to remove nail polish. The substance will easily dissolve plastics and is also effective against caulk. 

All you have to do is soak the corner of a towel in acetone and wipe the spots on your hand that have silicone on them. You should never pour the acetone directly on your hands as it can produce toxic fumes and strong, unpleasant odors. 

You can also use a hair dryer if you don’t have acetone at home. Silicone will gradually weaken when exposed to high temperatures, and a hair dryer is a good option for this task. You should turn the dryer on and make sure it blows hot air. Point it towards the affected area and allow enough time for the silicone to warm. 

Once you feel that the silicone has warmed up enough to be removed, you can use an abrasive material to get rid of it. When operating the hair dryer, start with the lowest power level and gradually increase it as necessary.
