Yes, that is a good point to clarify.
You are looking for an absorbent type of material to place over the wax, such as 2-3 folded paper towels or a brown paper garbage bag. You should remove as much of the solid wax manually prior to trying any method to remove the stain-
There are many different waxes used in candles (such as paraffin wax which is made from crude oil, bayberry, tallow, soy and bee's wax) and each type of wax has a different melting point.
The iron and paper works because the non greasy paper will absorb and wick away the heated and liquefied wax stain, make sure to move the absorbent material around as you apply heat to ensure the paper is absorbing all of the hot wax as it liquefies.
The hot iron method is a cheap, fast and easy way to remove some wax stains, it
*can* remove candle wax very nicely and up to the highest standards. The
"*" around the "can" in my previous sentence means
do not run off and fire up your iron- keep reading and make sure to pay attention to all the qualifiers/points I've listed below.
When using heat to remove wax, use the lowest heat possible so as not to scorch either the stain or the carpet. (yes, you can burn the carpet with an iron)
Consider both the color and type of fiber the carpet is made of prior to trying to remove the stain.
Carefully consider if the wax contains additives, such as fragrance or coloring. This could be a nightmare because some dyes will not "wick up" very well into the paper- so though the wax is removed very nicely with heat the dye still remains in the rug fibers. You are left with a candle wax dye stain which has been heated. Yikes!!
Since it is impossible for me to list all the variables involved, common sense should guide you, always using the lowest heat possible, checking your progress frequently.
Some stains may be "set" by heat, which essentially means that the stain and/or remaining residue is now thoroughly embedded in the item you have been working on.
If the stain is from pure uncolored wax, and the carpet is dark colored, and it is not in a very conspicuous location, I might be tempted to try this. But do take a cautious approach, using the lowest heat possible first to see how it is working out for you.
Per the question above, weimans wax away says that it "safely cleans tablecloths, carpet, furniture & other fabrics". You can get it for about $5.00(USD), and a little goes a long way.
The wax-away works just as if it has liquefied the wax, but no heat is used. You dab it on the stain, and the wax dissolves and breaks apart in a way that the iron/heat method will never accomplish.
(btw, I do not mean to sound fanatical about these type of products, but I've tackled
and lost the candle wax battle many times before. )
If your carpet/rug is light colored and/or the candle is colored, I'd just fork over the $5.00 and be done with it. It's not expensive and if you have ever washed or dried your clothing with a tube of chapstick that you forgot to take out of your pocket, you'll be ready to treat the chapstick stain using the wax away that you have handy in your cupboard-
Good luck and do let us know how it turns out.
