GHS hazard codes are quoted from the manufacturer’s Safety Data Sheet. PPE tiers below translate those codes and the listed ingredient chemistry; they are not CarCareTruth recommendations.

Only when: splash risk
Translated from the manufacturer’s Safety Data Sheet, Section 2
The H319 classification (serious eye irritation, Cat 2) carried over from the best-match reference SDS is the basis for eye protection during pour-fill where splash or tablet dust could contact eyes. DOKIKO's own label independently warns 'avoid direct contact eyes,' consistent with this tier. Situational rather than required because H318 (serious eye damage) is not indicated.
U.S. regulatory standard
29 CFR 1910.133(a)(1)
“The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from… liquid chemicals…”
ANSI Z87.1 (incorporated via §1910.6)
OSHA standards apply to workplaces. Cited here as the U.S. reference threshold for the underlying hazard class.

Only when: prolonged use
Translated from the manufacturer’s Safety Data Sheet, Section 8
No H311/H315/corrosive H-codes in the reference SDS. Dry tablet dust during handling can mildly irritate damp skin over prolonged or repeated contact, but a brief one-tablet drop into a reservoir has no chemistry basis for protection beyond that. The reference SDS's §8 generic protective-clothing/glove language is overridden as industrial boilerplate not backed by a skin-specific H-code.

Only when: handling concentrate · in enclosed space
Translated from the manufacturer’s Safety Data Sheet, Section 8
Section 8 of the reference SDS calls for suitable respiratory equipment in case of insufficient ventilation. Section 2 carries no inhalation-related GHS hazard code (H319 is an eye-only classification) and Section 11 lists acute inhalation toxicity and STOT (single and repeated exposure) as not classified, so this reflects generic ventilation boilerplate rather than a mixture-level inhalation hazard. Handling one individually wrapped tablet at a time keeps dust exposure minimal, but the SDS's own respiratory-equipment language is represented here rather than left off the page.

PPE tiers translate the manufacturer’s SDS and U.S. regulatory standards. Not professional safety advice. How we report safety.
Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.

TL;DR Summer-use only, no antifreeze, so the working solution freezes at 32°F just like plain water. A large owner base reports solid bug and road-film removal for roughly 13 cents per working gallon. Health score is 7.5/10, WARNING-class from an eye-irritation classification on an otherwise mild alkaline chemistry; no brand-specific SDS exists, so this translation is based on the closest verified SDS for the same tablet class.
Each individually wrapped tablet drops into a clean reservoir of water and dissolves in 15-20 minutes to make about a gallon of washer fluid, with 50 tablets covering roughly 52.5 gallons total from a single small bag. Rated for use above -5°C (23°F) for tablet stability, but the label is explicit that this is a summer formula that does not prevent freezing once mixed. A large owner base reports above-average removal of bugs, road film, dust, and bird droppings for a commodity tablet, with no notable streaking complaints. Winter use requires adding a de-icer or methanol additive per the label.
Best for daily drivers in climates that rarely see freezing temperatures, anyone who wants to avoid hauling gallon jugs home from the store, and buyers prioritizing low shipping weight and minimal plastic waste. Skip it if you're anywhere that regularly drops below freezing in winter without a separate additive plan, or if you specifically want a product backed by a brand-published safety data sheet rather than a closest-match chemistry translation.
WARNING signal word from an eye-irritation classification, the basis for eye protection during pour-fill where tablet dust could contact eyes; the label's own "avoid direct contact eyes" instruction lines up with that. No DANGER-level hazards and no Prop 65 ingredient identified. The fluid is drain-destined once sprayed on the windshield, but the underlying chemistry is not flagged as harmful to aquatic organisms, which keeps the environmental score above the category average despite the universal drain-path penalty.
No. Each tablet dissolves in plain water, and plain water freezes at 32°F. The product label itself states the formula does not prevent freezing and is rated only above -5°C (23°F) for the tablet's own stability, not for the working solution. For winter use, the label recommends mixing in a de-icer or methanol additive, or draining the reservoir until temperatures rise.
About 52.5 gallons. Each of the 50 tablets makes roughly one gallon (about 4 liters) when dropped into a clean reservoir of water and left to dissolve for 15-20 minutes.
The hazard classification behind this translation applies to the as-sold dry tablet, not the diluted working solution. Dry alkaline-cleaner dust can cause serious eye irritation on direct contact, which is why the label calls out avoiding eye contact and handling the tablets with care. Once a tablet dissolves into a gallon of water, the concentration drops well below that irritation threshold.
No Prop 65 warning appears on the package or in the available label images, and the chemistry class this tablet belongs to (a sodium-carbonate-type alkaline cleaner) is not on the OEHHA Proposition 65 list.
No. DOKIKO is a private-label Amazon brand that does not publish its own SDS. The health and PPE guidance here is translated from the closest verified SDS on file for the same class of product (a solid effervescent washer-fluid tablet), which is why the confidence level is marked unrated rather than verified.
