How to Fix Lava Lamp Wax Stuck at the Top?

If you suddenly find out that the lava in your lava lamp is doming up or clotted on the top, know that you are not the only one. This is a fairly common problem with the lava lamp. And we hear about it a lot. So don’t worry.


There might be a couple of reasons that lead to this incident. But, the good news is, this problem is fixable.

Let’s find out why it happens and how you can fix it very easily in more detail.

Why is the Lava in My Lava Lamp Stuck at the Top?

The primary reason that causes the lava in your lava lamp stuck at the top is when the wax separates. To be more specific, it happens when the lesser dense wax gets separated from the harder wax. 

When it happens, the harder wax blob floats upwards at the top and the less dense wax gets mixed in the clear solution and creates a minor clouding. Nonetheless, not getting heated up enough can be another reason for this problem. 

So, why and when does the wax get separated?— The simplest answer is when it gets shaken very badly. Especially when the lamp is neither hot nor it cooled down entirely, and suddenly it falls from a height, the wax can get dislodged and stuck at the top of the bottle.

How to fix the lava lamp wax stuck at top problem?

If the clotting isn’t caused because of an expired lava lamp, you can fix a temporarily clotted lava lamp through these following steps—

  1. Gently swirl the lamp around and try to move the clot of the wax to the middle or bottom. 
  2. Now turn on the lamp and let it run for a few hours until the lamp gets heated up enough to form the flow.
  3. If the light is not generating enough heat to initiate the flow, then try to replace the bulb with a higher wattage warm bulb.
  4. If the clot is still up there and the flow isn’t reaching the top, try to blow a hairdryer right over the clotted wax. Set it on its highest heat level so that it can melt the wax blob. 
  5. Once the stuck dome is softened and melted, hold the lava lamp carefully with a dry towel wrapped around it, and swirl it around slowly. 
  6. Now put it back on, and let it run for another few hours to properly form the lava flow again.
  7. If none of these tricks work, open the top lid of the glass bottle and drain out most of the liquid into a clean and dried vessel. Now, heat up the wax and let it melt completely. 
  8. Once it’s melted, pour the liquid back into the bottle using a funnel, seal the top and set it up all again. And you will be good to go.


Is Lava Wax Getting Stuck at the Top a Sign of Expiry?

It might be. But usually, it’s not.

Sometimes when the lamp gets shaken or falls off the ground, it creates a temporary blob stuck at the top of the bottle. It’s easily fixable.

But when you see it goes beyond fixing. And you notice that the clouding won’t go away even after you tried all that helps you fix a minor clouding, then consider it as a sign.


Can a Clotted Wax in a Lava Lamp Cause Minor Clouding?

Yes, it can. A minor clouding occurs when your lava lamp gets shaken a bit hard, or knocked over. 

Due to the sudden movement, the wax particles get dislodged and mixed into the solution. As a result, the lava wax deforms and sometimes gets stuck at the top and the clear solution becomes cloudy.

So, a minor clouding can happen when your lava wax is dislodged and clotted at the top.



Lava lamps getting stuck at the top is not anything new that occurs with lava lamps. However, it’s a quite tricky problem to fix without damaging the integrity of your lava lamp.

I hope you find this article helpful to fix your clotted lava lamp. But, before fixing it you need to be sure whether it’s a minor clouding or an expired lava lamp. 

In case of an expired lava lamp, we would recommend getting a replacement for your lava lamp rather than trying to fix it all by yourself.
