TL;DR Removes coffee, pet, wine, and food stains from both car carpet and cloth seats · works with brush-and-blot technique without a wet-vac. This is a concentrate requiring 1:20 dilution into a separate spray bottle before use. No SDS is on file; the health score (5.0) reflects the no-SDS default, not confirmed hazardous chemistry.
A concentrated formula for both car carpet and fabric upholstery · dilute 1 part to 20 parts water, spray onto the stain, agitate with a brush, and blot dry. Owner reviews from 2014·2020 confirm effective removal of coffee, wine, pet, and juice stains on both surfaces with no widespread pile-matting or color-shift reports. Marketing positions it as an enzymatic odor eliminator; specific enzyme chemistry cannot be confirmed without an SDS. Note that CWS_103 is discontinued · the CWS203 replacement uses a different, surfactant-only formula.
A reasonable pick for routine carpet and upholstery stain work if stock can be found and you're comfortable pre-diluting · the 1:20 ratio makes 16oz stretch considerably. Buyers wanting a ready-to-use option should look at CWS203 or another RTU fabric cleaner. Owners of Alcantara or suede should check compatibility first; no manufacturer guidance is available for specialty materials on this discontinued product.
No SDS is on file for this product · Chemical Guys removed CWS_103 from their library when it was discontinued. The health score (5.0) is the no-SDS default. Marketing states no ammonia, bleach, or solvents; these claims are unverifiable without an SDS. Sold as a bulk liquid concentrate (not a pump-spray bottle) · no aerosol or mist exposure modifier applies. Environmental footprint is estimated as leave-on pathway.
No. The CWS_103 formulation is discontinued and currently unavailable on Amazon. Chemical Guys replaced it with the CWS203 Foaming Citrus Fabric Clean (ASIN B06XPSP2HS), which uses a different surfactant-based formula. If the listing appears to have stock, verify before purchasing · the ASIN shows 'Currently unavailable' as of mid-2026.
The product label specifies 1 part concentrate to 20 parts water (1:20 ratio). A standard 16oz bottle mixed at 1:20 yields approximately 336oz of working solution. Mix into a separate spray bottle before applying · do not spray the concentrate directly onto fabric or carpet.
Community use patterns show brush-and-blot is the primary application method · spray the diluted working solution, agitate with a brush, blot with a microfiber or shop towel. A wet-vac or extractor improves results on heavily saturated carpet but the community record does not indicate it is required for routine stain removal.
No. These are different formulas with different ASINs. CWS_103 uses a marketing claim of enzymatic odor elimination via 'naturally occurring microbes.' CWS203 (the current replacement) is a surfactant-only formula with no enzyme chemistry per its published SDS · it does not carry the same odor-neutralization claim.
