Optimum Polymer Technologies, Inc. ONR Rinseless Car Wash Kit (32 oz) Version 5 — Big Red Sponge & 400 GSM Microfibre Towel

Optimum No Rinse Version 5 Kit is a complete rinseless car-wash system that cleans, protects, and dries vehicles with minimal water using ONR concentrate, a plush microfiber towel, and the original Big Red Sponge.

Built for enthusiasts and detailers who want a fast, low-water method to wash and maintain vehicles, this kit pairs Optimum Polymer Technologies' ONR Version 5 formula with the Big Red Sponge (BRS) and a 400 GSM waffle-weave microfiber towel. The ONR concentrate uses advanced polymers to encapsulate soil so dirt lifts from paint safely without a hose rinse, while the BRS and microfiber help remove grime and leave a streak-free finish. Everything in the set is made in the USA and designed to work together whether you're doing a quick spot-clean or a careful detailing session.

How does ONR Version 5 clean without a lot of water?

ONR Version 5 is a concentrated soap that emulsifies and traps dirt particles in a lubricating solution, letting you wipe contaminants away without dragging them across the surface. The polymer blend creates a protective barrier between grit and paint, reducing scratches during the wash process.

• Mix ratio: 1 ounce of ONR per 2 gallons of water for standard rinseless washes.
• Encapsulation: Polymers surround soil for safe removal with a sponge or towel.
• Lubrication: Reduces marring and swirl marks while you clean.
• Versatility: Also usable as a clay-lube or for motorcycles, boats, RVs, and aircraft.

What role do the Big Red Sponge and microfiber towel play?

The Big Red Sponge is engineered with more surface area and durability than common sponges, making it ideal for applying ONR and lifting grime without excessive pressure. The included 400 GSM waffle-weave microfiber towel dries and buffs surfaces to a streak-free shine, finishing the job quickly.

• BRS sponge: Large contact area speeds cleaning and reduces passes.
• Waffle microfiber: Ultra-plush texture absorbs quickly and resists streaking.
• Safe combination: Sponge applies solution; towel removes residue and polishes.
• Reusable: Machine-washable sponge and towel for long-term use.

Can I use this kit in a garage, on drought days, or for vehicles other than cars?

Yes—ONR's rinseless method is perfectly suited for low-water scenarios and enclosed spaces because it needs only a bucket, a small amount of water, and the kit components. Its gentle but effective formula works on a wide range of surfaces beyond cars.

• Near-waterless: Clean a whole vehicle with 1–2 gallons plus minimal runoff.
• Indoor-safe: Ideal for garage washes when hoses aren’t practical.
• Multi-vehicle: Use on motorcycles, boats, RVs, and aircraft exteriors.
• Seasonal use: Handy in winter when outdoor rinsing is limited.

How do I get the best results and avoid common mistakes?

Follow the recommended dilution, work one panel at a time, and keep the towel and sponge clean to prevent reintroducing contaminants. Replace water in the bucket if it becomes visibly dirty and use a two-bucket or grit-guard approach when possible for extra protection.

• Measure: Use 1 oz ONR per 2 gallons for general washing; adjust for spot cleaning.
• One-panel workflow: Spray or apply solution, agitate with BRS, then wipe with microfiber.
• Maintain: Rinse sponge and flip towel faces regularly during use.
• Storage: Air dry components between uses to preserve longevity.

Who is this for: This kit suits home detailers, weekend car enthusiasts, mobile detailers, and owners of multiple vehicle types who want an efficient, low-water cleaning system. If you value paint protection during cleaning, need a portable solution for indoor or drought-restricted washing, or want professional-level results without complex gear, the Optimum No Rinse Version 5 Kit delivers the chemistry and accessories to make rinseless washing reliable and repeatable.
