It’s no secret that silicone is a great material for bath and kitchen applications. Silicone offers watertight sealing, insulation against heat or cold, and it’s easy to clean. But if you’ve ever tried to soften silicone in the tube before applying it, you know how difficult it can be. It just doesn’t seem to want to cooperate! The same goes for removing old silicone from around your tub or shower. It can be a real pain.

But don’t worry, we’re here to help. In this article, we’ll show you how to soften silicone effectively—for easier application or removal.

For Easier Application

There are many ways to soften silicone in the tube before applying it. Some of the most effective ones are listed below.

Method One: Hot Water

If you’re trying to soften silicone in the tube for easier application, here’s what you need to do:

1. Start by heating up some water on the stove. You’ll want it to be hot, but not boiling.

2. Cut the tip-off of the silicone tube and place it in the hot water.

3. Leave it in the hot water for a few minutes to soften up.

4. Once it’s softened, you can apply it as normal.

5. If it starts to harden up again, just heat up more water and repeat the process.


There are a few things to keep in mind when using this method:

  • Make sure you heat the water up enough. If it’s not hot enough, it won’t soften the silicone.
  • Don’t leave the silicone tube in the hot water for too long. If it gets too soft, it will be difficult to work with.
  • This method is best for small jobs. If you’re trying to do a large project, it might be easier to use the oven method.

Method Two: Oven

If you’re working on a larger project, you might find it easier to use the oven method. Here’s what you need to do:

1. Preheat your oven to 200 degrees Fahrenheit.

2. Cut the silicone tube open so that it can lay flat on a baking sheet.

3. Place the baking sheet with the silicone on it in the preheated oven.

4. Check on the silicone every five minutes or so to see how it’s progressing.

5. Once the silicone is soft, you can remove it from the oven and proceed with your project.

Keep in mind that this method can be messy, so you’ll want to make sure that you’re working in a well-ventilated area. You should also wear gloves to protect your hands from the heat.

Method Three: Hairdryer

If you’re working on a small area, you can use a hairdryer to soften silicone.

1. Turn the hairdryer on to the hottest setting and hold it about an inch away from the silicone.

2. Keep moving the hairdryer back and forth until the silicone is soft enough to work with.

For Easier Removal

If you’re trying to remove old silicone from around your tub or shower, here are a few methods that you can use.

Method One: Scraping

You will need:

  • A putty knife or razor blade
  • A hairdryer

1. First, using your putty knife or razor blade, score the silicone caulk. Make sure to only score the caulk and not the surface beneath it.

2. Next, turn your hairdryer onto the high setting and direct it at the scored caulk.

3. After a few minutes, the heat will cause the caulk to soften and you should be able to easily remove it with your putty knife or razor blade.

Method Two: Chemical Removal

You will need:

  • A caulk remover (can be found at your local hardware store)
  • A putty knife or razor blade

1. First, locate the silicone you want to remove. If it is old and dried out, you may need to scrape away some of the material with a putty knife or razor blade to get to the fresh silicone underneath.

2. Liberally apply the caulk remover to the area

3. Let it sit for the amount of time recommended on the product label

4. Use a putty knife or razor blade to scrape away the softened silicone

5. Wipe away any residue with a damp cloth


  • If you’re trying to remove silicone from a sensitive surface, like acrylic or fiberglass, you may want to avoid using chemicals.
  • If the silicone is difficult to reach, you may need an extension tube for your hairdryer.
  • You may need to use a combination of methods to get all of the silicone off.
