Learn how to use Nikwax Tech Wash to clean waterproof jackets and technical outerwear without damaging water repellency. Step-by-step washing tips and common mistakes.

Quick answer

Use Nikwax Tech Wash as a standalone cleaner for waterproof and technical outerwear: dose it directly into the wash, use a gentle cycle, and skip conventional detergent entirely. This preserves the garment's water-repellent finish and avoids residue that attracts water.

Why regular detergent undermines technical outerwear

Conventional laundry detergents often contain additives, brighteners, and conditioners that leave a hydrophilic film on fabrics. On a waterproof jacket, that film can mask the durable water repellent (DWR) finish and cause the surface to wet out even when the membrane is intact. Tech Wash is formulated without those additives, so it cleans without leaving a water-attracting residue. That is the core of tech wash vs detergent: one is designed to rinse clean from technical fabrics, the other is not.

When washing is the right fix—and when it is not

Washing is the first thing to try when a jacket stops beading water or feels clammy. Dirt, sweat, and oils can clog the fabric surface and make the DWR seem worn out. A proper wash often restores performance. However, if the garment has physical damage such as delamination, seam tape peeling, or a tear, washing will not repair it and may worsen the issue. Also, do not wash a jacket that is still visibly dirty with mud or grit without rinsing off loose debris first—excess soil can overload the wash and reduce cleaning effectiveness.

How to wash technical outerwear with Nikwax Tech Wash

Prep the garment: Close all zippers, Velcro, and flaps. Brush off loose dirt or mud, and empty pockets. If there are stubborn stains, pre-treat them with a small amount of Tech Wash rubbed in gently—do not use bleach or fabric softener. Checkpoint: never wash a jacket with sharp objects or debris left in pockets; they can damage the fabric or machine.
Dose Tech Wash correctly: Follow the bottle instructions for your load size. Typically, use one full cap for a single jacket or a small load. Pour it directly into the detergent dispenser or drum—not into the fabric softener compartment. Checkpoint: using too little cleaner leaves dirt behind; using too much may require an extra rinse to avoid residue.
Choose the right cycle: Select a gentle or synthetic cycle with a warm wash (around 30–40°C / 85–105°F) and a low spin speed. Avoid heavy-duty cycles, hot water above 40°C, and extra spin, which can stress seams and coatings. Checkpoint: if your machine has a 'waterproof' or 'outdoor' setting, use it—otherwise a gentle cycle is the safe default.
Rinse thoroughly: Ensure the machine runs a full rinse cycle. If you see suds remaining, run an additional rinse. Residual cleaner can attract water and reduce DWR performance. Checkpoint: after rinsing, the water in the drum should look clear, not soapy.
Dry to reactivate DWR: Tumble dry on low heat for 20–30 minutes, or follow the garment care label. Gentle heat helps redistribute the DWR finish. If the label forbids tumble drying, hang dry away from direct heat. Checkpoint: do not overdry; remove the jacket while slightly damp if you plan to apply a spray-on DWR treatment afterward.
