In your spotting arsenal be sure to carry inspection tools such as a high-intensity light, microscope, pH pen, and black light. Be sure to have ample supply of Q-tips, white towels, tamping brush and spotting spatula, in addition to your spot-and-stain cleaning agents.
A general rule is to never tell a client that a spot is not removable without first conducting a proper inspection. Use the microscope in front of the client. The microscope will show deep dye damage to fiber and also exhibits knowledge coupled with sophistication. The pH pen is indispensable when analyzing stains. Can analyze whether a stain is acid or alkaline in nature. The use of the pH pen exhibits extreme use of technology, which people know takes education and equates to value in the clients eyes.
If you detect deep dye damage when using the microscope, see if you can get transfer to a white towel when you blot the stain with your spotter. If you do not get transfer to the towel, it’s safe to tell the client there is a stain. If the client wants the technician to try advanced techniques it must be noted on the contract, or use a waiver form indicating you will not be held responsible if the area becomes lighter in color or texture due to application of advanced techniques.
Basically, you are trying to restore an already-damaged carpet with cleaning techniques in which a positive outcome is not always attainable. Carpet repair and spot-dyeing skills come in real handy at this point, and will help keep your client satisfied with your work. You have the ability to offer the client a solution to the problem by repairing or spot dyeing (where applicable) the carpet. When you advise a client there is absolutely nothing you can do about a stain, it adds an unnecessary negative tone to the job. If you don’t already possess these skills, be sure to take a carpet repair and spot-dyeing course either through the IICRC or your local trade association.
Identification of a spot is the first step towards removal or correction. Spots can be identified as one of the following: solvent-soluble, water-soluble or non-soluble. Solvent-soluble spots are generally oily or greasy in nature. They do not dissolve easily in water based cleaning agents and respond better to solvent based detergents. Water-soluble spots result from a wide range of materials such as food spills, body fluids, waste materials, etc. The spotting agents for these types of spots are usually detergent-based although there are some agents that work on protein based spots and contain enzyme digesters. Non-soluble spots are comprised mostly of soil and sand. Soil and sand cannot be dissolved by either water- or solvent-based cleaning agents; however, the sticky substance causing soil or sand to adhere the carpet fibers can be dissolved. Pre-vacuuming and application of a spot removal agent best suits this type of spot.
Let’s review the basics when it comes to spot and stain removal procedures:
- Safety first. Always read all label directions before using any spotting agent. If solvents are used obtain permission and immediately increase ventilation. Use safety glasses and chemical resistant gloves.
- Procedures. Remove encrusted material. Blot excess liquid spills with an absorbent white towel. Dry vacuum particle spills, i.e. soil. You must get as much material off the carpet as possible before you apply spotting solutions.
- Never use any cleaning solutions without testing the carpet or fabric for color fastness before proceeding. See IICRC S100 and IICRC S300.
- Do not use too much solution too quickly. Work in stages. Use products in small amounts until the desired results are achieved.
- Work from the outside of the spot toward the center. After applying the cleaning solution, agitate with a spotting spatula. Do not use your hands, and wear gloves.
- Never scrub, only tamp with your spotting brush. Use your tamping brush and a towel to absorb the material.
- Certain spotting agents take a few minutes to work. Read the product instructions.
- The area must be sufficiently rinsed after application of spotting solutions. Use a spotting machine or portable extractor, truckmount, etc. to rinse. After rinsing, tamping with a dry absorbent material helps remove excess moisture and prevent wicking problems.
These procedures are fairly general in nature, but offer a basic understanding of spot and stain removal. Professional training through the IICRC or trade associations will be necessary for success and to limit your liability. There are also online programs, videos and CDs, as well as manuals available on the topic of spot and stain removal.
If you desire true business success, immerse yourself in education. I have found in my personal experience the more energy and time I spend studying the technical world of textile maintenance, the more I find how much I don’t know. This inspires me and increases my thirst for knowledge. As an educator I believe studying your field or craft is a lifelong journey. Experience is also crucial. It takes time and practice to master one’s craft.
