Many detailers of today know better than to use a crusty old sponge to wash a car. A 'sponge" can cause scratches, paint marring, and it's better at pushing around dirt than picking it up. However, Optimum Polymer Technologies just changes the way we look at auto detailing and the use of a sponge. The Big Red Sponge is made SPECIFICALLY for use with Optimum No-Rinse wash. The sponge has cuts to contour to body panels and get into hard to reach areas, all while picking up dirt. The ONR encapsulates the dirt and provides lubrication for the sponge to wipe across the surface. The sponge CANNOT be used with soap and water. Hence why the BRS is a washing system meant for ONR. Many people are skeptic about this wash system until they try it, and each person is always blown away by how safe and effective it is. Try it for yourself and let us know your thoughts about NEW and IMPROVED sponge washing in the comments.
New Formulation
Optimum No Rinse Wash & Shine is yet another amazing product from Optimum Polymer Technologies. Optimum pathed the way showing how a wash should be done with restricted water.
Everybody knows about waterless washing and the damage it can do to the paint. Optimum No Rinse puts a clever twist on this environmentally friendly method of washing using "rinseless washing" or what some people refer to as "semi-waterless" washing.
Optimum No Rinse involves a single bucket of water and no hose. You simply wash the surface down with the solution, and then dry! No rinsing is required and many litres of water are saved.
This method is ideal for water-restricted areas, or those living in an apartment building or inner-city dwellings where a hose is not accessible or practical.
Detail spray is one of the most used items a detailer can use. You can go through a lot of detail spray even during just one detail. The list of uses for detail spray are endless and here are just some of the uses below:

Optimum offer the only alternative product that cleans AND protects your vehicle and protects the environment too. It will reduce the water usage to a fraction of a conventional car wash. No Rinse Wash & Shine is the most technologically advanced car wash system to date, that requires just a single bucket of water to wash an entire car. Optimum No Rinse & Shine (as the name suggests) does not require rinsing with a hose since there are no soapy surfactants to wash off into the storm drains.
This unique product contains substantive polymers that bond to the paint and protect it from abrasion during the wash. These polymers offer greater protection and lubrication than conventional car washes and leave a slick and glossy finish behind afterwards. The waste water in the bucket can be used to water the lawn or disposed of into a sink, where it will be treated. Other additional benefits of No Rinse Wash & Shine are faster washes, the ability to wash anywhere at anytime including washing inside the garage during winter, no messy runoffs, and a better looking finish. These are just some of the reasons No Rinse Wash & Shine is being used by many people across the world, saving millions of litres of water every day.

|---|---|
| Change-of-mind returns | Store credit only, within 30 days of delivery, unopened & unused |
| Restocking fee | 10% of item price |
| Return shipping | Paid by the customer |
| Non-returnable | Chemicals/liquids, Ceramic Coatings, and all Kranzle & Big Boi products |
| Faulty / damaged / incorrect items | Report within 10 days: repair, replacement or refund, no fee |
| Order cancellation (before dispatch) | Refund to original payment method, minus 3% transaction fee |

Nothing in this policy limits or replaces your rights under the Australian Consumer Law (ACL). If a product has a major or minor failure (for example, it's faulty, unsafe, not fit for purpose, or significantly different from how it was described), you're entitled to a repair, replacement, or refund under the ACL, regardless of the store credit, restocking fee, or timeframe terms below.
The terms in the rest of this policy apply to change-of-mind returns and other situations that aren't covered by a consumer guarantee.
We accept change-of-mind returns for store credit only, on items that are unopened and unused, within 30 days of the delivery date.
Due to safety, hygiene, and quality control, the following are never eligible for change-of-mind return:
Unused, unopened accessories such as brushes, pads, and towels may be eligible, subject to approval from our team. Email us first with your order number and photos before sending anything back.
If you believe a product isn't working properly, contact us first rather than returning it straight away. Here's how we handle it:
If you've told us in advance the specific job you needed a product to do and it can't do that job, let us know. That can still count as a failure under the ACL even if the product otherwise works normally.
For orders shipped to New Zealand, if a polisher/buffer or pressure washer needs to be sent back to us for inspection, repair, or a warranty claim, return shipping is paid by the customer. Given the cost of international freight, we're not able to cover shipping on these two product categories for New Zealand orders, even where a fault is confirmed.
Yes, if you ordered the wrong product, return it under the policy above and place a new order for the correct item.
You can cancel an order any time before it's been processed or shipped. A 3% transaction fee (covering payment processing costs) is deducted from the refund; the remainder goes back to your original payment method.
Once an order has been processed or dispatched, it can no longer be cancelled, but you can still return the items under the Change-of-Mind Returns policy above.
Notify us within 10 days of delivery at info@detailingshed.com.au with your order number and clear photos. We'll arrange a replacement, or a refund if stock isn't available, at no cost to you. If we need the item sent back to us first, we'll cover or reimburse that return shipping too, since the item is faulty, damaged, or incorrect rather than a change of mind (this doesn't apply to New Zealand orders for polishers/buffers and pressure washers, per above).
For any return worth over $50, we recommend a trackable shipping service or shipping insurance. We're not responsible for returned items lost in transit.
If your order hasn't arrived, please allow 7–15 business days after Australia Post or the courier begins their investigation. We'll be in touch once it's resolved and any refund or replacement has been processed.
Product packaging or colours may differ from the images on our site due to manufacturer updates. This isn't grounds for a refund unless the product itself is faulty or incorrect.
Discount codes must be applied at checkout and can't be added retroactively to an existing order, and we can't refund the difference after an order is placed. Double-check your code before completing checkout. If it's not working, contact us before you finalise your purchase.

"Very easy to use"
"As a professional detailer using Optimum No Rinse Revision 6, I couldn’t be happier with the results. The updated formula has incredible slickness, making wash media glide effortlessly over the paint while safely lifting dirt away. It leaves a clean, glossy finish with zero streaking and works perfectly as a rinseless wash, clay lube, and quick detailer. Super efficient, safe on all exterior surfaces, and a massive time saver for both maintenance and full details. Revision 6 is definitely a step up, highly recommended!"
"Good!"
"Very good and versatile product. Highly recommend"
"I always skeptical of rinseless washes. A recent event lead me to try ONR and it’s became my new favourite for removing baked on bugs, road grime and general dirt on the car and in the home. If you’re considering it, I’d say it’s worth a try. You might just be surprised!"
"Have used it twice and is the best product I have used, so easy no scratches no marring will be buying more great stuff thanks"
"You can use this stuff for everything; claying, interior cleaning, cleaning glass, washing your car (paint), etc, etc, etc. The list goes on. Optimum seriously cooked with this one, amazing product. Maintenance cleaning is so much faster using this than the traditional two-bucket method."
"Best quality product ever. 💯 👍🚘"
"I've been using this product on both interior and exterior clean of my client vehicles and it did not disappoint!"
