Knowing the source of the rug stain goes a long way to
correcting the problem. Further, there are basically two categories of
stains, color added and color subtracted.
Color added stains are typically created by solids or liquids
imparting their color compositions from dyes. This type of stain
requires removing all of the substance residues first through flush
extraction. After this technique what is left in the fiber is generally
the "color added dyes". Beverages, food products and a host of
household sundry products usually have a fixed amount of food color
dyes, or dyes to create a desired marketing appeal. There are color
reducers, oxidants, used carefully and conservatively that can reduce
the "color added" alteration, but it may also be necessary to color
correct using air brush techniques with acid dyes.
The second category is color subtracted. This
is caused typically by substances such as hair products, tile cleaning
products, etc. that have oxidizers or bleach in their composition. Now
depending on the concentration of these bleaches or oxidants, the
success derived from color repair is variable. It is necessary to
neutralize and thoroughly rinse out residues front and back of the
affected area contaminated. At this point using fiber redying
procedures, original colors can be restored.
"Pet urine stains", the question is age, old, new. The procedure
for successfully reversing a urine stain varies somewhat because of the
PH nature of urine, Old stains become alkaline, new stains are acidic,
therefore, reversing procedure is tricky, further, there is a pigment
color that has to be treated like the aforementioned "color added"
explanation. The success of these procedures also depend upon the fiber
types, nylon, wool, polyester, olefin and cotton. These procedures are
best qualified and rendered by professionals at Augusta RugWorks.
