What You Should Know About Interior Detailing
While a great deal of emphasis is placed on paint finishing in detailing, little information is disseminated about what is needed to properly clean vehicle interiors. This article is an attempt to provide detailers with an entire process for interior detailing including: interior materials, detail chemicals, detail equipment and tools.
When a detailer attempts to clean the interior of a vehicle, he must know all of the different materials involved. each material will require different cleaning procedures. This means the detailer must have a full understanding of all these various materials and what the problems might be and how to solve them. The materials are: fabric or vinyl (headliners); fabric, vinyl or plastic (trim); vinyl (dashboards); vinyl, plastic and clear plastic covers (panels); nylon (carpets); and vinyl-protected leather, fabric or vinyl (seats) I will not address the particulars of each of these materials, but as a detailer you must have a complete knowledge of what they are, the problems you can encounter and the knowledge to correct the problems.
Interior chemicals
Professional detailers should only use chemicals that are formulated to clean a particular interior material. Carpet shampoo should be used for carpets, leather cleaner for leather, glass cleaner for windows, etc. Too many detailers and chemical suppliers encourage the use of chemicals formulated for other purposes as interior chemicals. This can have harmful effects on the material. For example, a typical practice of many detailers, encouraged by misguided and unprofessional chemical suppliers, is to use an engine degreaser for interior cleaning on carpets, vinyl and leather. Will it clean? Yes, this chemical will clean, but the difference is that the materials in an engine (metal, rubber, etc.) are much different than more delicate interior materials. It would be like washing your car with dishwashing detergent or taking a bath in laundry detergent.
An engine degreaser has a pH of 12 to 14, due to the inclusion of caustics, like sodium hydroxide, which can destroy carpet and upholstery fibers and damage leather very easily. even the use of a less-aggressive, all-purpose cleaner on carpets is not a good practice because they lack the brighteners and softeners that are formulated into the carpet shampoo for obvious reasons.
The list of chemicals a detailer should use for interior cleaning includes: carpet and upholstery shampoo; vinyl cleaners; leather cleaners; low pH all-purpose cleaners; stain removers (protein, grease, red dye, coffee/tea, rust and pet stains); glass cleaner (ready-to-use or concentrated); leather conditioners; protectants; water-based silicone dressings; biological odor eliminators; fragrances; equipment and tools.
Many detailers cannot afford all the equipment and tools listed below, but they are listed so you know what a professional detailer should have in his arsenal to do the work correctly. These items are: air compressor with blow guns (an essential); wet/dry vacuum; heated soil extractor (absolutely essential); vapor steamer (not essential, but very useful for cleaning hard surfaces and removing stains); ozone generator (not essential, but does wonders in removing odors and mold spores from air-conditioning systems); air or electric rotary shampoo tool; nylon scrub brushes; small detail brushes; Scrubbie pads (a Teflon-net-covered sponge for scrubbing vinyl, leather and plastic surfaces); applicator pads (for dressing and leather conditioners); and towels (different colors for cleaning chemicals and windows).
The process
