How to remove it using an iron and absorbent paper.
Spilt wax is pretty easy to remove. All you have to do is take some white absorbent kitchen towel and an iron. Put the iron on a low heat and place a double layer of kitchen towel over the wax, don’t let the iron touch the carpet. Keep moving the paper towel around for maximum absorption and continue until the wax has gone.
Here is a demonstration video showing the process.
