Description
The job, and the laundry this is built around
Nathan Power Wash is a sport specific laundry detergent from a running accessories brand. The problem it addresses is real and it is not the problem an ordinary detergent solves. Technical activewear is built from tightly woven synthetics, often with a wicking finish, and those fibers hold body oils in a way cotton does not. The residue builds up wash after wash, it is what smells when the shirt warms up, and it is also what stops the fabric moving moisture the way it did when new.
Nathan describes exactly that mechanism, saying the formula removes the layer of grime where germs live and breed and cause the smell, and that once the residue is gone the technical fabric performs as if new. Note what that claim is and is not: it is a claim about removing residue, not a claim about killing anything. There is no antimicrobial claim on this listing and no registration behind one, which is the correct position for a laundry detergent to take.
The company also says it works on sport gloves, protective pads, braces and other equipment, which extends it beyond the wash basket. If your laundry is ordinary household washing, a mainstream detergent from the liquid detergent category does that job for less.
What the listing claims, and the number it never gives
Nathan describes the formula as all natural, free of toxicity, pH neutral, scent free, biodegradable and made in the USA, and states that it works in all washing machines. Those are the manufacturer’s own descriptions. Terms like natural and biodegradable are Federal Trade Commission environmental marketing areas rather than defined chemical descriptions, and a blanket statement that a cleaning chemical carries no toxicity is not something we will restate.
The two claims worth taking seriously are the concrete ones. Scent free matters on activewear, because fragrance deposited on a wicking fabric is one more thing sitting in the fiber. And pH neutral matters because elastane, the stretch fiber in almost all compression and performance gear, degrades faster in strongly alkaline conditions than in neutral ones. Those are the right specifications for this application, whatever you make of the rest.
There is no volume, no dose and no load count
This listing never says how much detergent is in the bottle. There is no fluid ounce figure, no load count and no dose per wash anywhere on the page. The recorded item weight is 2.62 pounds, which suggests something around a quart, but that is an inference from a shipping weight rather than a specification. For a detergent, dose and load count are the two numbers that decide both cost and whether the machine rinses clean, and neither is published. Read the bottle.
No ingredient list appears either. No surfactant, no enzyme, no chelator. Several specification fields on this record are also unusable: Specific instructions for use reads “Biodegradable”, Skin type reads “All”, Mildewresistant reads “Free Of”, Department reads “Unisex-Adult”, and Included Components lists running accessory categories. None of those describe the product.
Fabrics, machines and the thing to keep away from activewear
Nathan says the detergent works in all washing machines and names activewear, workout clothes and sports equipment as targets. The company does not name any fabric to avoid, and with no enzyme information published, wool base layers deserve the usual caution, since protease enzymes damage protein fibers and a merino running top is an expensive test case. Wash one item first.
The more useful guidance is about what not to add. Fabric softener is the enemy of technical fabric. It works by depositing a conditioning film on the fibers, and that film is precisely what blocks wicking and traps odor, which means using a softener alongside a performance detergent undoes the thing you bought the detergent for. The same applies to scented dryer sheets. If you want scent in your laundry, put it somewhere other than your running kit, and the fabric deodorizer category covers the products that do that job on other loads.
Two further practical points that no detergent fixes on its own. Do not leave damp kit balled up in a bag, because that is where the residue turns into a smell which is much harder to remove afterward. And wash in cool or warm water rather than hot, since heat sets body oils into synthetic fibers and can damage elastane.
Using it on equipment, and storage
Cleaning gloves, pads and braces is the part of this listing that needs the most care, and Nathan gives no method for it. Protective equipment usually contains foam, hook and loop fasteners, molded plastic and stitched panels, and machine washing any of those can delaminate the foam or destroy the shape. Check the equipment manufacturer’s own care instructions first. Where washing is permitted, hand washing in a dilute solution and air drying away from direct heat is generally safer than a machine cycle, and equipment should never go in a dryer.
On storage and handling, keep the bottle capped, upright and out of reach of children, which applies to every laundry product regardless of how it is described. Rinse skin with water on contact and keep it out of eyes. A product described as neutral and gentle is still a concentrated detergent in the bottle.
Never combine it with another laundry product in the same pour. Do not mix it with bleach, do not add an oxygen booster into the same cap, and do not layer it with a separate odor treatment on the same load. The formulation is undisclosed and no interaction can be predicted. If you want to add a booster, add it to the drum separately according to its own instructions.
Cost, and the alternatives
Cost per load cannot be calculated from this listing, because neither the volume nor the dose is published, and that is a genuine obstacle to judging value. What can be said is that specialist sport detergents cost more per bottle than mainstream liquids, and the case for one rests entirely on whether you actually have the residue problem. If your kit smells fine after a normal wash, you do not need this.
The alternatives split by approach. The OUT ProWash targets the same persistent odor problem and can be used as a booster alongside a normal detergent, which is often the more economical route. The Woolite Damage Defense is aimed at fabric wear rather than odor, and the Purex liquid detergent is the mainstream benchmark to price against. For equipment rather than clothing, a surface product such as the Purefypro sports equipment spray treats pads and gloves without wetting them through, though it carries its own documentation problems. And if you want fragrance added deliberately rather than as part of a detergent, the Dirty Labs scent oil puts it in the dryer instead.
Who should buy it, and who should not
Buy it if your workout clothes have stopped smelling clean after a normal wash, you want a scent free and pH neutral formulation for technical fabric and elastane, and you will stop using fabric softener on those loads. The rating history of 1,090 reviews at 4.6 stars is solid. Skip it if your laundry is ordinary household washing, if you need a volume and a dose before you can judge cost, if you need an ingredient list, or if you were expecting an antimicrobial product, which this is not and does not claim to be.
