CCT Spotting Techniques & Stain Removal 4

Question 1

A nail polish stain on a nylon carpet would BEST be treated with which spotter?

Accepted Answer

Acetone or non-oily nail polish remover applied carefully

Answer

Acetone dissolves nail polish, but it must be used carefully and tested first because it can damage certain fiber types and dye systems.

Question 2

When treating a dye stain from a colored beverage or marker, what type of spotter is typically employed after initial blotting?

Accepted Answer

Reducing or oxidizing agent designed for dye removal

Answer

Synthetic dye stains often require reducing agents (for certain dyes) or oxidizing agents to chemically break down the chromophore structure of the dye.

Question 3

What is the risk of over-wetting carpet during the spotting process?

Accepted Answer

It can cause wicking, delamination, mold, and mildew in the backing and pad

Answer

Excess moisture saturates the backing and pad, extending drying time and creating ideal conditions for wicking, mold growth, and potential delamination.

Question 4

For a fresh ink stain from a ballpoint pen, which approach is most effective?

Accepted Answer

Use a dry-solvent or isopropyl alcohol to dissolve the oil-based ink carrier

Answer

Ballpoint ink is oil-based, so a dry-solvent or isopropyl alcohol effectively dissolves its carrier, making the pigment easier to blot away.

Question 5

A technician notices a yellow discoloration in carpet that appeared after using a high-alkaline spotter on a wool rug. What most likely occurred?

Accepted Answer

Alkaline hydrolysis damaged the wool protein fiber, causing yellowing

Answer

Wool fibers are protein-based and highly sensitive to alkaline chemicals; high-pH spotters cause alkaline hydrolysis and yellowing, so near-neutral or mildly acidic spotters must be used.
