If your rubber hose is too stiff and difficult to work with, there are a few ways to soften it up. With a little time and effort, you can make your rubber hose more flexible and easier to use. One way to soften hard rubber hose is to soak it in hot water.

This will help loosen the material and make it more pliable. You can also try using a hair dryer or heat gun to gently heat the hose. This will also make the material softer and more flexible.

Glycerin to Soften Rubber

Using glycerin to soften rubber is a simple process that can be done at home with just a few ingredients. Glycerin is a clear, thick liquid that is often used in cosmetics and other beauty products because it helps to keep things moist and prevents them from drying out. It also has lubricating properties, which makes it ideal for use on rubber.

To soften rubber with glycerin, simply add a few drops of glycerin to the item you want to soften and rub it in until the glycerin is evenly distributed. You can then leave the item to sit for a few hours or overnight before using it, and you should notice that the rubber is significantly softer than it was before. If the rubber is still too hard for your liking, you can repeat this process until you achieve the desired result.

Glycerin is safe to use on most types of rubber, but if you’re unsure about whether or not it will damage your particular type of rubber, it’s always best to test it on a small area first. Once you’ve confirmed that using glycerin won’t damage your rubber item, feel free to apply it liberally!
