Optimum No Rinse Wash and Shine Version 5 - Rinseless Car Wash Soap

In this review of Optimum No Rinse Wash and Shine Version 5, the bottom line is simple: this gallon concentrate is for car owners who want a fast, low-water way to clean and protect their vehicle while maintaining a high gloss. It excels as a rinseless car wash that uses only 1 oz per 2 gallons of water, making it economical for repeated use. The updated Version 5 formula increases lubricity and gloss while the polymer blend helps lift and encapsulate dirt so you can safely wipe surfaces without traditional rinsing.

Key Features

• Concentrated formula: One ounce per 2 gallons of water yields many washes, making the gallon size cost effective for regular use.
• Polymer protection: The blend of polymers encapsulates and emulsifies dirt to reduce direct contact with paint and lower the risk of swirls.
• All-in-one cleaning: Safe for exterior paint, ceramic coatings, glass, trim, wheels and even interior surfaces like leather and vinyl.
• New Version 5 shine: The 2023 reformulation increases lubricity and delivers improved gloss and longer-lasting surface protection.
• Rinseless and eco friendly: Minimal water use allows indoor or off-season detailing in a garage and supports water conservation where restrictions apply.
• Clay lube versatility: Can double as a clay bar or clay mitt lubricant to aid contamination removal without risking paint contact.

Who It's For

Optimum No Rinse Version 5 is best for enthusiasts and weekend detailers who want a quick, effective clean with minimal water and equipment. It suits people who park indoors or live where cold weather or water restrictions make traditional rinsing impractical, and it pairs well with microfiber towels, a bucket, and a sponge or clay tools.

Those who prefer a pressure rinse to remove heavy grime or who need an alkaline wheel cleaner for brake dust should consider a separate specialized product, as ONR is optimized for general exterior and interior cleaning and encapsulation rather than aggressive decontamination.

Pros & Cons

Pros

• High dilution rate makes it very economical per wash.
• Polymer-rich formula provides improved gloss and a slick feel that helps reduce marring.
• Versatile for exterior and interior surfaces and usable as a clay lubricant.
• Enables near waterless washes indoors, conserving water in drought-prone areas.

Cons

• Not a substitute for heavy-duty decontamination; very dirty wheels and engine bays may need stronger cleaners.
• Proper technique and clean microfiber towels are required to avoid dragging trapped grit when wiping.

Frequently Asked Questions

Can I use this on ceramic coated cars?
Yes. The formula is safe for ceramic coatings and is designed to clean while leaving polymers that add slickness and gloss.

How much water do I need per wash?
Mix 1 oz of concentrate with 2 gallons of water; one gallon of concentrate yields many washes depending on vehicle size.

Is a rinse really unnecessary?
For routine light to moderate cleaning, no rinse is required when used with good microfiber towels and proper technique; heavy grime or brake dust may still need traditional rinsing or specialty cleaners.
