About Renumax

Using a proprietary formula that fills your car’s superficial scratches, scrapes, and scuff marks with tiny micro-particles, Renumax Scratch Remover goes on quick and can help you avoid expensive sanding, polishing, or buffing. In fact, the company claims Renumax can provide professional results in seconds, whether you own a car, motorcycle, boat, RV, and more.

To use Renumax, you just have to follow these simple steps:

  1. Shake the bottle of Renumax.
  2. Apply the formula directly to the scratched area. This is accomplished using a convenient applicator sponge that spreads the formula easily over a wide area—even curved surfaces.
  3. Allow time to dry, which should only take minutes.
  4. Use a microfiber cloth to remove excess liquid or residue.

Then, regardless of your car’s color or finish, the company claims Renumax will do all the work and provide a “smooth clean shine that protects your car for years.”

As our cars get used and abused over the years, all the small scratches and scrapes can really add up, making them look almost as bad as if they were in an accident. The difference is that these smalls scuffs don’t really warrant an expensive trip to the body shop, so a product like Renumax makes perfect sense: help your car look better for a lot less!

Is this what you can expect, though? Will Renumax give you similar results to a body shop? Will it even work at all? And is it worth rolling the dice? We’re here to keep you informed, so we’ll cover all of this—and more.

How Does Renumax Work? Is It Unique?

Nowhere on the Renumax website or in the commercial are we told what Renumax’s “proprietary formula” actually contains, so there’s no way to know exactly how it works.

Fortunately, there are several products out there just like Renumax, including popular options like Scratch-dini and Scratch Away. All of these products use a substance known as BFGoodrich Carbopol resin, a “registered trademark for a series of polyacrylic acids used as gelling agents” which are “are white, fluffy powders.” We’re not told exactly how these substances work to fill in surface scratches on cars, but a company press release from 1998 claimed they’re “used as thickeners, stabilizers and emulsifiers in a wide range of personal care, household, textile, industrial and coatings applications and are also used as excipients in pharmaceuticals.”

Is this what’s contained in Renumax? If so, then it’s only proprietary to BFGoodrich, and not to Renumax’s manufacturer.

Regardless of who makes it or how it works, what can you realistically expect from the Carbopol resin found in Renumax?

Will Renumax Work as Advertised?

Here on HighYa, Scratch-dini had a 1.4-star average rating from 66 customers at the time of our research, most of which complained that it didn’t work as advertised (or at all). In fact, more than one reader noted that Scratch-dini actually made scrapes and scratches even more noticeable.

Granted, it doesn’t matter which Carbopol-containing product we’re talking about, most customers complain of the same thing. Does this necessarily mean you’ll experience something similar with Renumax? We didn’t test the product directly so there’s no way to be sure, although we think this other customer feedback is worth considering strongly before placing an order.

Pro tip: Just remember that products like Renumax only work on superficial imperfections, which generally means they haven’t made it past your car’s clear coat. Anything deeper and you’ll definitely need to enlist the help of a professional body shop.

Next, let’s talk about price.

How Much Does Renumax Cost?

One bottle of Renumax will cost you $19.95, plus $13.95 S&H. For this price, you’ll receive one bottle of Renumax and one bottle of Smart Polish (based on all appearances, this seems to be similar to Armor All).

Also included with your order is a “free” bonus car vacuum, for which you’ll have to pay an additional $13.95 S&H.

All Renumax orders come with a 30-day refund policy, less S&H charges (we’ll talk more about this next). In order to request a refund, you’ll need to contact customer service.

Important note: There wasn’t any contact information listed on the Renumax website at the time of our research, so we’ll keep checking back and will update this review once it’s posted.

Running the Numbers: Putting Renumax’s Cost Into Perspective

Before wrapping things up, it’s important here to really drive home Renumax’s price in comparison to its value. Let’s lay it out, shall we?

There’s no mention how big Renumax’s bottle is, but based on pictures shown on their website, it could probably fit in the palm of most adults’ hands. The smart polish appears to be even less bulky.

The point is that Renumax’s manufacturer will charge you almost $14 in shipping for a couple items that probably don’t weigh much more than a pound. In addition, while a car vacuum might come in handy, the company’s forcing you to purchase theirs (instead of exploring other options on your own and making a more informed purchase) and charging you an additional $14 for the privilege.

To top it all off, the nearly $28 you spend in S&H charges—40% more than the cost of the product itself—is non-refundable if you’re not satisfied. In fact, by the time you ship it all back to the company, you end up losing $10+ more in S&H than what you’ll get back as a refund.

Pro tip: The Renumax website didn’t indicate if your order will come with a microfiber cloth, so be sure to factor this into your overall cost as well.

Renumax Price BreakdownBy the time you check out, due to Renumax’s S&H charges, the final cost may end being a bit more than you were originally expecting.

But is your satisfaction with Renumax all about price?

Will Renumax Renew Your Car’s Paint Job?

Even Renumax cost twice as much, you’d probably still buy it as long as it worked as advertised, right? After all, who wouldn’t want to get rid of unsightly scratches and scuffs on their car, without paying an expensive body shop to do it for them?

However, considering that there are at least 2 other products currently on the market that are essentially identical to Renumax—neither of which come with high marks from customers, this could speak volumes about what you might expect to experience. On top of this, you’ll pay almost $30 in non-refundable S&H on your Renumax order, which could be a big stumbling block from an overall value perspective.

Based on these two factors, a wise (and money conscious) choice might be to explore local Carbopol resin options before placing your Renumax order. Why? Although they might work equally well as Renumax, you could save yourself a boatload in S&H charges—especially if you’re not satisfied and decide to process a return.

    So bad I wrote to the ASA about it

    This product and its claims were so misleading I wrote to the Advertising Standards Authority (ASA) about it.

    I have just heard my complaint has been upheld and that they will insist on the advertisement no longer being broadcast by Best Direct in the UK.

    Bottom Line: No, I would not recommend this to a friend

    Renumax illusion

    Based on the TV demonstration I ordered with high expectations. Result:

    1 . Once applied the white substance does NOT evaporate as shown on the TV. Once dried it must be wiped off.

    2. The light scratches are even more visible as before the repeated treatment.

    3. Big disappointment. I want to ask for a refund. How do I proceed?

    Bottom Line: No, I would not recommend this to a friend
