Optimum No Rinse Wash and Shine Version 6 (ONR), 32 Oz Review (2026)

What Changed in Version 6

Optimum No Rinse Wash and Shine Version 6 is the latest update to a rinseless wash formula that Optimum has revised repeatedly over more than twenty years. The company says the new polymer technology improves how the product encapsulates dirt and creates a stronger barrier between grime and the finish while you wash, and it leaves a noticeably slicker, glossier feel both while washing and while drying afterward. It is sold in this 32 oz size along with 8 oz and gallon options, and it uses the same rinseless approach as earlier ONR versions, where the car is washed and wiped dry using a small amount of water rather than a hose.

Dilution Ratios for Different Jobs

Version 6 keeps the multi-purpose dilution chart that made ONR popular. For a standard rinseless wash, the guidance is about 1 oz of concentrate per 2 gallons of water. As a clay lube, mix roughly 2 oz per gallon so the clay bar glides safely over the paint. A waterless wash, sprayed and wiped without a bucket, calls for about 8 oz per gallon, and the same 8 oz per gallon ratio is used for a quick detailer spray. Interior cleaning and glass cleaning both use a slightly lighter mix, around 6 oz per gallon of water. Because one bottle covers so many uses, it helps to label a few spray bottles for each dilution rather than remixing from scratch every time.

Surfaces It Is Made For

Optimum markets Version 6 for a wide range of surfaces beyond bare paint, including ceramic coatings, paint protection film, matte finishes, glass, plastic, vinyl, leather, and carpet, which makes it useful as an all in one wash and interior wipe down product. The underlying idea is the same substantive polymer technology used in earlier ONR versions, where a lubricating layer forms over the surface during the wash so dirt slides off into the wash media instead of scratching the finish, and that layer is designed not to interfere with any wax, sealant, or ceramic coating already on the car.

Who Should Pick Version 6 Over Version 5

Anyone starting fresh with rinseless washing, or an existing ONR user who wants the newest formula, is the target buyer for Version 6, since Optimum designed it specifically to build on the lubricity and gloss of the older Version 5. The tradeoff is subtle rather than dramatic. Long time ONR users switching from Version 5 may notice a smoother feel during the wash and a slicker result when drying, but the core rinseless method, dilution habits, and bucket routine carry over unchanged, so there is no relearning involved when upgrading.

Getting the Most From the Concentrate

Because ONR is sold concentrated, measuring accurately matters more than with a ready to use spray. A small kitchen measuring cup or a marked squeeze bottle helps avoid guessing, which both saves product and keeps the wash solution at its intended strength. Wash one panel or section at a time, wipe it dry with a clean microfiber towel before moving on, and keep switching to a clean face of the towel or mitt as it picks up grime. Used this way, the 32 oz bottle is meant to outlast many wash sessions compared with a diluted ready to use wash soap.
