How to Remove Silicone Sealant WD40: Easy Steps to Follow

Silicone sealant is a great way to keep water out and protect your home, but it can be a pain to remove when you need to. If you’ve ever tried to remove silicone sealant without the right tools, you know it’s not an easy task.

Thus WD40 comes in. WD40 simply stands for the perfect displacement of water on the 40th attempt. The product was designed to coat tools and parts to help them resist corrosion.

This article will provide you with steps you can follow to get rid of that old silicone sealant from your job.

Simple Steps on How to Remove Silicone Sealant WD40

Silicone sealant is a kind of sealant that is mostly used at home as it does not damage your partitions. It also makes the house look beautiful and well-maintained from the outside.

However, when a large section of the sealant needs to be removed, for instance, for a new painting project, it can prove to be a little difficult. If this is your case, you need the following steps on how to remove silicone sealant WD40 easily.

Step 01: Prepare for the job

Before you begin removing the silicone sealant, you need to prepare for the task. Take the necessary tools with you, including a scraper, clothes, WD40 spray, and paper towels.

These are all you need before starting this project. If it is your first time working with silicone sealant remover, ensure that you have a bucket of water and a sponge to clean up.

You should also wear protective clothing, such as gloves and goggles before you start this project.

Step 02: Clean the Area

Before anything else, ensure that you clean the area. Remove all items piled up around the place so you can access them easily. You should be aware that this sealant is not easy to remove, and it might leave stains if not done right.

If there are any imprints on your wall, you can rub them with a wet cloth before proceeding to avoid this. Clean all the other items you have used, including things that are not supposed to be just lying around the house.

Step 03: Apply WD40

This is where you apply WD40 to the areas that are affected by the old silicone sealant. If there is any residue, cover it with a paper towel and spray WD40 on it generously to make it soft.

At this point, you should use the scraper to remove all residues from your separators without damaging them in any way.

You should do this carefully without exerting too much force on the barriers to avoid any damage. Ensure you are not applying WD40 near your eyes or nose as the chemicals might irritate them.

Step 04: Remove all Remnants

Once you have scraped off all remnants of silicone sealant from your wall, clean it with a paper towel soaked in WD40. Ensure that you clean the wall with a sponge if there is any staining.

At this point, the wall should be looking new again after all remnants have been removed fully. You can now proceed to repaint or redo your work, depending on what you want at the end of the day.

If there are any stains on the wall, ensure that you clean them using a wet cloth before repainting.

Step 05: Clean Yourself

Once you have completed everything, ensure that you clean yourself using plenty of water and a sponge. Follow the instructions on your protective clothing before you discard them or wash them. Ensure that none of the WD40 remains on your body as this could irritate it.

This process is quite simple if you follow each step meticulously. If there are no residues of WD40 on your body, you can move around the house as usual without any worries.

You should go through such steps before buying a silicone sealant removal product, as it might prove to be exactly what you need in such situations.

Additional Factors to Consider

There are some other factors to consider when removing silicone sealant, which is as follows:

i) Ventilation:

Ensure that the room is well-ventilated before you proceed to remove the old silicone sealant. Ensure there are no children around as WD40 can harm them if they come in contact with it directly.

ii) Remove Stains:

If there are any stains left on your fences, remove them immediately. If you leave them for a long time, they will become more stubborn, and it will be difficult to remove them even with the silicone sealant remover.

iii) Protect your Furniture:

Ensure that you protect your furniture using protective covers before starting this project. If WD40 gets on them, it can lead to discoloration of the items, which you might not be happy with.

After all these steps, you can now proceed to paint your partitions without any worries. Ensure that you clean the wall before applying the new paint so it can adhere well to the surface.

Frequently Asked Questions

Here are some questions that might come to your mind during all these steps. They are as follows:

How Long Should You Leave WD-40 on Silicone?

If you are using WD-40, ensure that you leave it on for about half an hour before scraping the job. This should be more than enough time for the chemical to loosen up all residues of the old silicone sealant.

Does Vinegar Remove Silicone Sealant?

This process is a bit trickier, which is why WD-40 works best in such situations. Vinegar is not recommended for use in such cases unless you have been doing the job for a very long time.


If you are using WD-40, ensure that you follow all the above steps carefully without fail. This is because there are many ways in which people tend to remove silicone sealants, and most of them involve harsh chemicals.

If you do not want to risk it, go through all these steps before making up your mind about buying any product for the same purpose. This will also ensure that you do not end up with any regrets later on.

If you have successfully removed the old silicone sealant without damaging your job, proceed to repaint it immediately, so it looks new again. Once this is done, you can happily live in the house without worrying about anything at all.
