Why is it so hard to remove?
The oily soils are so small, that they not only form an electrical bond, but they may also fit very nicely onto the very sites on the fiber designed to hold the color of the carpet, also known as "dye sites". It makes the filtration soil hard to remove with carpet cleaning solutions alone.
Homemade cleaning solutions will probably have little or no effect on the soil, and may actually damage the carpet and prevent it from being able to be removed.
If you decide to tackle the job yourself, you will need to assemble a few basics.
Carpet Cleaning Solution, or Carpet Spotting Solution
A small brush with fine bristles, a small dish brush would work
A Citrus Solvent Gel
Start by cleaning the spot with a mild carpet cleaning solution, and agitate the spot by gently tamping ( tapping the bristles on the carpet and solution). Do not scrub the spot! You can unravel the fibers or damage them, leaving a fuzzy and possible irreparable spot.
Rinse the solution with clear water and blot the excess with a towel, again NO SCRUBBING!
IF the spot comes out, consider yourself blessed and fortunate. Don't expect that result, because it rarely happens.
IF the spot remains, again the likely outcome, grab your citrus gel. The reason for using a gel is because solvents can destroy the backing of the carpet and separate it from the carpet face, known as "delaminating or delamination".
This carpet damage can be repaired only from the back of the carpet by a professional. Gels are less likely to seep into the back of the carpet and cause damage. Search for carpet gel at a local carpet cleaning supplies store, look in the yellow pages to find yours.
Should you remove the spot yourself?
ATTENTION: Use the following method only on synthetic carpet fibers, applying hydrogen peroxide or ammonia to natural fibers like cotton, wool, silk, hemp, or any other natural fiber may cause it permanent damage. Seek the advice of a local professional.
Apply the gel and again tamp it with your brush. Before rinsing, if the spot still remains, then you will need to apply the hydrogen peroxide.
Apply the Hydrogen Peroxide with a trigger sprayer. Let it dwell on the stain for a few moments, and then spray a little ammonia on the spot. Ammonia will activate the Hydrogen Peroxide. This is a great trick for red wine stains as well.
If the spot is along a baseboard or next to woodwork or wood flooring, some additional precautions need to be taken. I've seen more than one paint job or finished piece of wood in need of repainting because of poor planning.
Use a piece of wood, plastic, or cardboard to protect surfaces from chemical damage or damage from the agitation or brushes. I've found that a piece of plastic cut from an old milk or water jug works exceptionally well.
Can filtration soil be prevented?
Soil Filtration lines can be prevented to some degree with a little forethought and planning.
First of all, have Fabric Protector applied with every cleaning. Some companies have programs in place that offer a discount on future cleanings when fabric protection is used,
Secondly, consider having a the air spaces along stairs and baseboards caulked or sealed before staining occurs, or when the filtration soils are removed. A professional company may be able to offer these services concurrently with the filtration soil removal. Always ask, because it will most likely cost less to call out one service company than two.
We have a $2.00 per ft charge for this service, we suggest that you pull back your carpet around affected areas and seal the area with caulking.
