At $26.08 for a gallon with 4.8 stars from 9 reviews, this is a promising but limited-data product. The anti-resoiling technology is the differentiator here.

Buying Guide: Auto Carpet Cleaning Selection
Concentration and Dilution
Professional carpet cleaners are typically sold concentrated and diluted before use. Higher concentration ratios (60:1 like P&S Extractor) mean more economical use per gallon. Consumer products are usually ready-to-use or low-concentration. For volume use, concentrated products dramatically reduce per-application cost.
Foam vs. Foam-Free
High-foam products work well for hand scrubbing and brush application but clog extraction machines. Foam-free or low-foam products work with extractors. Know what application method you're using before purchasing. The P&S Extractor Shampoo is specifically foam-free for machine use. The Chemical Guys Fabric Clean and Nanoskin use foaming chemistry for hand application.
Enzyme vs. Detergent vs. Citrus Chemistry
Enzyme products break down organic materials chemically, best for pet stains, food, and biological contamination. Detergent products lift soil through surfactant action, best for general dirt and grime. Citrus products degrade grease and oil specifically, best for particularly greasy contamination. For a first-use universal product, enzyme or detergent cleaners cover most situations. Citrus (Carpet Bomber) is best for heavily contaminated, greasy interiors.
Pre-Treatment vs. Shampoo
Serious stains benefit from two-step treatment: enzyme pre-treatment spray followed by shampooing. The pre-treatment breaks down the stain compound; the shampooing removes the residue. Using only shampoo on protein-based stains (food, pet, blood) cleans the surface but may not fully remove the staining compound, which can reappear after drying.
Machine vs. Hand Application
Extraction machines (carpet cleaners) produce significantly better results than hand scrubbing for deep carpet cleaning. They inject water/cleaner under pressure and extract the dirty water simultaneously. For serious interior cleaning, a rental carpet extraction machine ($30-40/day) plus a professional concentrate like P&S Extractor Shampoo produces professional results. Hand application with a brush is appropriate for spot treatments and maintenance.
FAQ
What's the difference between carpet shampoo and carpet cleaner? The terms are used interchangeably in most contexts. Shampoo typically implies a foaming formula. Cleaner is more generic. Both refer to products that clean carpet fibers. The meaningful distinctions are formulation (enzyme, detergent, citrus) and application method (hand, machine, extractor).
Can I use household carpet cleaner on car carpet? Household cleaners like Bissell and OxiClean work in cars, carpet is carpet. Products specifically designed for automotive use sometimes address the grease and road grime contamination more effectively than home-focused formulas. Either can work.
How do I clean car carpet without a machine? Spray cleaner on the carpet, scrub with a stiff brush or drill brush, and extract the dirty liquid with a wet-dry vacuum. Multiple passes produce better results. Pre-treating stains before scrubbing significantly improves outcomes.
How do I get pet odors out of car carpet? Enzyme cleaners specifically break down the uric acid crystals in pet urine that cause persistent odor. Standard cleaners clean the surface but don't address the crystals. The P&S Terminator enzyme formula is the appropriate product for pet odor removal.
What causes car carpet to feel stiff after cleaning? Detergent residue left in carpet fibers attracts new soil and causes stiffness after drying. Rinse thoroughly after cleaning, or use a detergent-free formula like Chemical Guys Fabric Clean that avoids this problem by formulation.
How often should car carpet be shampooed? For a daily-driver vehicle: at minimum once per year as part of a thorough interior detail. If food spills or muddy shoes are common, more frequently. The key is not waiting until stains are set deep into fibers, surface-level spills are dramatically easier to remove than set-in staining.
