Candles can tip and spill molten wax on the carpet. It may
happen fairly often if you're a candle lover. Fortunately you
can get candle wax out of carpet. It isn't always easy,
but the wax itself can be removed with patience. The dyes in
the wax are another issue, and getting those out depends on what's
in the particular dye.
If you happen to get to it while it's still in liquid or semi-liquid
form (not likely, but maybe), see if you can soak up some of
the molten wax with paper towels, but use only un-dyed white
ones. This will at least make for an easier clean-up when you
get to the hardened gob that is left. Then follow the steps below.
1. To begin with, scrape as much wax out of the carpet as
you can, with a spoon. Then put an ice cube on the wax to freeze
it. Leave it there for a minute. The wax should harden enough
to break it up and get more of it out.
2. Now, to get the rest of the candle wax out of the carpet,
put a clean brown paper bag over the spot, and place a clothes
iron on it, set on low. The wax will liquefy and transfer to
the paper. Apply a new paper bag as often as necessary until
you get out all of the wax. This may take a little time.
Note: Avoid paper bags that are printed with colorful ink
or you might add to your staining problem. You can cut those
parts out of the bag if it has logos or colored designs.

3. If this doesn't get all of the wax out of the carpet, you
can try rubbing alcohol. This may help with some of the staining
from dyes in the wax as well. Using a white cloth or a plain
white paper towel wetted with the alcohol, dab at the area. Repeat
this with a fresh towel until you get no more transfer of wax
or dyes to the towel.
4. Whichever method you use to get the candle wax out of the
carpet, when you are done, rinse the area with clean water, blot
up the excess, and dry the area quickly.
If all else fails, professional cleaners who use hot-water-extraction
(steam cleaning) will be able to remove the candle wax. The heat
generated by a good truck-mount unit is usually enough to melt
any residue and the suction is powerful enough to pull it from
deep in the fibers. A good cleaner will also know how to remove
many dyes that may have migrated into the fibers.
