Windex is one of the most recognized glass-cleaner brands in the country, and most parents searching "is Windex toxic" already have a bottle under the sink (a spray, a pack of wipes, or one of the ammonia-free variants) and want a sourced answer about the specific bottle they own, not a blanket verdict on the brand. EWG's Guide to Healthy Cleaning has rated several Windex glass-cleaner formulas, and the grade depends on which exact product is on the label. Here's what EWG's published data says about one specific Windex formula and where higher-rated alternatives exist in the same category.
EWG grades are published by the Environmental Working Group at ewg.org/cleaners. Windex's parent company updates formulas over time, and sells more formulas than this article covers, so verify the current grade for your specific bottle before assuming an older or newer rating still applies.
What EWG Rates About Windex's Glass Cleaner Formulas
| EWG Guide Grade | Product | Flagged Concerns (per EWG) |
|---|---|---|
| F | Windex Ammonia-Free Glass Cleaner, Crystal Rain | EWG's record shows no data for asthma/respiratory concerns on this specific formula; overall grade is F |
Source: EWG Guide to Healthy Cleaning (ewg.org/cleaners). Windex Ammonia-Free Glass Cleaner, Crystal Rain: ewg.org/cleaners/products/1399-WindexCrystalRain/. Windex sells other glass-cleaner formulas, including an Original Glass Wipes pack and an original spray-bottle cleaner; neither had a grade we could confirm against two independent sources as of this writing, so neither is cited here. Verify the current grade for your specific bottle at ewg.org/cleaners before purchasing. These grades are the independent work of EWG; NonToxicFinder is not affiliated with EWG.
What an F Grade Means on EWG's Scale
EWG's Guide to Healthy Cleaning scores products A through F using a weight-of-evidence approach that combines ingredient hazard data with how completely the brand discloses its formula on the label. An F sits at the bottom of that scale. It is not a government safety finding, a recall, or a clinical result: it reflects EWG's analysis of the disclosed (and undisclosed) ingredients against its own hazard criteria.
For Windex Ammonia-Free Glass Cleaner, Crystal Rain, EWG's record shows no data for asthma and respiratory concerns on this specific formula, yet the product still grades F overall, a reminder that the letter grade reflects the full weight of EWG's ingredient and disclosure assessment, not any single category. Windex sells other glass-cleaner formulas, including a wipes format, but this article only cites the grade we could confirm against two independent sources, so it doesn't speak to those other formulas one way or another.
This Windex formula does not carry the EWG VERIFIED® mark, which requires a Grade A or B in the Guide, passing EWG's additional ingredient screening, and full ingredient disclosure including individual fragrance components.
Is Windex Toxic? What the Data Shows
There isn't a single yes-or-no answer, because the grade depends on which bottle is on the shelf. EWG's Guide to Healthy Cleaning rates Windex Ammonia-Free Glass Cleaner, Crystal Rain at Grade F. That grade reflects EWG's independent assessment of disclosed ingredients and formula transparency, not a regulatory finding or a health guarantee, and it doesn't extend to every Windex product on the shelf. Other Windex formulas exist and this article only speaks to the one grade it could independently confirm. Families following EWG's guidance typically look for Grade A, Grade B, or EWG VERIFIED® products in this category, and the Windex formula checked here does not currently reach that tier.
EWG-Rated Alternatives for Glass and Window Cleaning
The products below carry either the EWG VERIFIED® mark or a Grade A in EWG's Guide to Healthy Cleaning. EWG VERIFIED® is the stricter designation: a product must score Grade A or B in the Guide, pass EWG's additional ingredient screening, and disclose every ingredient on the label, including individual fragrance components. Grade A alone reflects EWG's database assessment of publicly available ingredient information without that same direct-disclosure requirement.

Frequently Asked Questions
Q: Should I stop using Windex around my kids based on this EWG grade?
EWG's Guide to Healthy Cleaning grades Windex Ammonia-Free Glass Cleaner, Crystal Rain at an F. EWG grades are not government safety findings, and NonToxicFinder makes no independent health claim about Windex. Families following EWG's guidance can look to the EWG-rated alternatives above as lower-concern options per EWG's published data. For personal health guidance, consult a qualified medical professional.
Q: Do all Windex products get the same EWG grade?
Not necessarily. This article covers one specific formula with a grade we could confirm against two independent sources in EWG's Guide to Healthy Cleaning: Windex Ammonia-Free Glass Cleaner, Crystal Rain, at Grade F. Windex sells additional formats and formulas, and grades can differ by product and by formula update. Verify the current grade for your specific bottle at ewg.org/cleaners.
Q: Does EWG certify or endorse Windex?
No. EWG is an independent nonprofit that rates and verifies consumer products against its own published standards; it does not certify or endorse brands, including Windex. NonToxicFinder is also not affiliated with, endorsed by, or partnered with EWG. The grade in this article is EWG's own published data, cited here for reference.
Q: What's the difference between an EWG Guide grade and EWG VERIFIED®?
These are two distinct EWG assessments. Guide grades (A through F) score a product in EWG's Guide to Healthy Cleaning database by ingredient hazard and disclosure completeness. EWG VERIFIED® is a separate, stricter mark: a product must score A or B in the Guide, pass additional EWG ingredient screening, and disclose every ingredient, including individual fragrance components, on its label. ATTITUDE and AspenClean in this article carry the EWG VERIFIED® mark; ECOS and Better Life carry a Grade A in the Guide; the Windex formula checked here reaches neither tier.
Q: Does "ammonia-free" mean a Windex formula is better rated?
Not automatically. Windex Ammonia-Free Glass Cleaner, Crystal Rain still grades F in EWG's Guide to Healthy Cleaning despite dropping ammonia from the formula, because the grade reflects the full ingredient list and disclosure completeness, not the presence or absence of any single ingredient. NonToxicFinder makes no independent safety claim about this or any other formula; the grade above is EWG's own assessment.
