Method 1: Rubbing Alcohol

Rubbing alcohol is the first use and easiest method. It can be an effective solution for removing suction cups that are stuck to surfaces. It’s also helpful for removing rubbing compounds that won’t come off

Here’s a step-by-step guide on how to use rubbing alcohol to remove a suction cup:

Required Materials:

These are the material you need for the job. 

  • Rubbing alcohol (70% Isopropyl alcohol) 
  • A clean microfiber towel 


Now that we know what materials you need, let’s move on to the process.

  • First, pour some alcohol into a container. Then, soak the towel with the rubbing alcohol.
  • Now, dip the cloth or paper towel into the rubbing alcohol solution directly. Ensure that the suction cup is thoroughly saturated with the rubbing alcohol.
  • Allow the rubbing alcohol to penetrate the suction cup for a few minutes. This helps to weaken the suction and make it easier to remove.
  • Then, apply a circular motion to the melted suction cup until it detaches.
  • Finally, clean the surface with water properly. 

That should do the trick.

  • And rubbing alcohol 


Let’s get started now that we know the procedure.

  • Apply a small amount of the household cleaner directly onto the melted suction cup. Make sure to cover the entire affected area.
  • Now, scrub the surface and eliminate the melted dirt or debris that may hinder proper adhesion.
  • Then, thoroughly rinse and dry the surface after scrubbing.
  • Finally, remove any residue by cleaning the surface with rubbing alcohol.

Method 3: Adhesive Remover

To remove a melted suction cup from a windshield, use a quality adhesive cleaner. Follow the procedure to do this:

Required Materials:

Before we begin, let’s familiarize ourselves with the materials you’ll need.

  • A good adhesive cleaner
  • A microfiber cloth 
  • And water 


Knowing step-by-step procedures can help you o do the job perfectly. 

  • Take a small amount of the adhesive cleaner. And apply it directly onto the melted suction cup. Make sure to cover the entire affected area.
  • Then, rub the melted suction cup in a circular motion using the cloth until it detaches.
  • Clean the surface by wiping it with water to eliminate any residue.
  • Finally, you need to ensure that the surface is thoroughly dried after cleaning.

Method 4: Blade

Don’t freak out! You can remove the melted suction cup from the windshield with the help of a blade. It is also a handy tool for removing silicone from car paint

However, using a blade to remove a melted suction cup requires caution to avoid damaging the surface. Follow the steps below to do that.

Required Materials:

The first thing you should do is learn about the tools required for the job.

  • A pair of safety gloves
  • A sharp blade
  • And proper lighting 


It is possible to accomplish a task perfectly if you know the steps to follow.

  • Hold the blade at a shallow angle against the windshield, with the sharp edge facing away from you. Take caution not to scratch the glass.
  • Begin scraping the melted suction cup off the windshield using the blade. Apply light pressure and work slowly to avoid scratching the glass. Take your time and proceed cautiously. 
  • You can also use Windex while doing this to lube the blade when it starts to slide off the windshield. 
  • After removing the melted suction cup, clean the area with rubbing alcohol to eliminate any residue. This will help ensure a clean surface.

How to Prevent Suction Cup From Melting 

It is better to prevent than to cure. In order to avoid such a situation, you should be careful. You can prevent this situation by maintaining some tips. 

  • Always opt for suction cups made from heat-resistant materials such as Neoprene or high-temperature-resistant rubber. These materials have higher melting points and are less likely to deform or melt under normal conditions.
  • To prevent suction cups from melting and losing their grip, it is important to avoid subjecting them to excessive heat. High temperatures can lead to the melting and deterioration of the suction cup’s material, which compromises its effectiveness. 
  • It is advisable to remove suction cups from the windshield when they are not in use. Leaving suction cups attached to the windshield for extended periods can expose them to heat buildup. That later leads to the risk of melting and potentially harming the glass.
  • You should refrain from using suction cups with gel or adhesive backing. These types of suction cups are more prone to melting under elevated temperatures. That can harm the glass surface.

Why Won’t My Suction Cup Stay on My Windshield?

You may be using a low-quality suction cup if your glass suction cups do not adhere to the glass surface. In order to increase the suction cup’s effectiveness, some manufacturers recommend wetting it or warming it before use. When the suction cup is wet, it will be able to grip and function better on the glass.

I am a professional automotive and car mechanic. I have been in the industry for 15+ years. At the moment I have 3 garages. Every day dozens of cars come to our repair shops that are damaged in a very short period of time. The main reason for this is not taking a proper care of the car.
