There is an ever-growing number of dashcams now being purchased due to the very low cost of them along with the YouTubers out there that want to stick you making the tiniest of driving errors, on the internet for all to see!

This has been the case for sat navs over the last 10 years with them becoming almost an essential tool of driving rather than an expensive toy for the few.

With the technology in mobile phones now as well, these are also now used as sat navs in vehicles.

This is all great and a big step forward in helping the motorist get around and film their journey. However, what is the single point of failure for all of these devices? – the stupid suction cup that never sticks correctly to your windscreen, falls off mid-drive, falls off if is too hot and falls off if it is too cold!

Mine was evening falling off at night and setting my car alarm off – so before I got lynched by the neighbours and driven out with pitch folks, I thought I had better find out how to make this stupid suction cup for (in my case) my dashcam stick to the screen.


I started off like all good men ignoring the instructions and insisting that I knew best and I could get this simple piece of technology stuck to my windscreen. After weeks of it falling off, I gave in and started to Google it.

There are so many people out there with ways of doing this but most of them are just either stupid or messy. I saw one guy in the US using a cigarette lighter to “slightly melt” the cup and then stick it on. I even came across a blog post of a guy in Russia using super glue to stick it?! madness.

The more I looked the more fed up I got of watching videos and reading blogs of people who clearly wanted nothing more than to break their dashcam and knackered their windscreen for good.

So, I started talking to some of the sales guys at work – the ones that have to have dashcams in their company vehicles and spend half their lives in a vehicle. They all said the same thing and that they have never had a dashcam fall off their screens since using this method which I will shortly share with you guys reluctantly reading this blog post!

So, full of nothing but hope, I tried out their method and it worked, I could not believe it. It stuck straight on and five months later, it’s still there and never fallen off.

The Proven Method

So, what is this wonderful method I hear you cry? Well, it is extremely simple, will not make a mess and will not damage your vehicle’s windscreen. I’ve made this a step-by-step guide below so you can easily read and share this information if you so wish.

  1. Make sure your windscreen is clean – very clean. Also, ensure that there are no chemicals or residue on the area you wish to place your device. Best to use either a lint-free cloth or a kitchen roll
  2. Boil a kettle of water and pure into a bowl.
  3. Very carefully, hold the suction cup (not the plastic bit, but the rubbery bit) in the boiling water for about 60 seconds.
  4. Take the suction cup out of the water and dry it thoroughly but carefully – again, use a kitchen roll so as to not leave any dust or fibres on the suction cup.
  5. Whilst it is still hot, push the suction cup onto your windscreen where you want to place it.
  6. Push hard, as hard as you can, onto the windscreen but (if your device has one) do not pull the suction cup lock lever.
  7. Keep pushing hard on the suction cup for about 1-2 minutes, not just a few seconds.
  8. Whilst still pushing, pull the suction cup locking lever into place. This should be quite hard to pull due to the suction it already has, but this is good, just go ahead and pull it hard enough for it to lock into place.
  9. Let go and then leave it for 30-60 minutes.
  10. Attach your device carefully to the suction cup (if it is not attached) and that’s it!

You should then find that the suction cup will take in place and is very sturdy and it should stay there for as long as you want it there.


We would love to hear your feedback on this guide and see if it has helped anyone else apart from myself! Just leave us a quick note below in the comments section and go ahead and feel free to share this guide with all folk out there that have to face this annoyance every day!

Thanks for reading….
