Always Wash Before You Re-proof – Here's Why

By TaVare · updated 2026-07-27

The most common mistake with proofing is skipping the wash. New water-repellent treatment does not bond to dirt, body oils or detergent residue – so if you proof a dirty jacket, you waste both the product and your time. Here is why, and how to wash correctly first.

Why a dirty jacket cannot be proofed

The proofing (DWR) has to bond to clean fibres to lie evenly and bead water. Dirt, body oils and detergent residue form a layer between the fabric and the product, so the proofing bonds poorly and unevenly. A clean jacket takes the treatment; a dirty one does not.

Wash correctly first

Use a wash made for technical garments, and avoid anything that leaves a film.

  1. Close zips and hook-and-loop fastenings, and empty the pockets.
  2. Wash with a technical wash – not ordinary detergent with additives.
  3. Skip fabric softener entirely: it clogs the pores and counteracts the proofing.
  4. Run an extra rinse to clear all residue before you proof.

Then you proof

On a clean jacket you can use wash-in (in the machine) or spray (on the outside), then activate with a little heat – a short tumble on low heat or ironing with a cloth in between. See the separate guide on re-proofing a shell jacket for the details.

Never use fabric softener

Fabric softener is proofing's worst enemy. It forms a film, clogs breathability and stops the DWR from bonding. Always use a technical wash for shell garments.

Frequently asked questions

Do I really have to wash the jacket before proofing?+

Yes. Proofing does not bond to dirt or detergent residue, so proofing a dirty jacket wastes the product.

Which detergent should I use?+

A technical wash made for shell garments, never one with additives – and never fabric softener.

Can I wash and proof in one round (wash-in)?+

Some products allow it, but a clean jacket first gives the best result. Check the product.

Can you do it for me?+

Yes. We wash and re-proof according to the garment and its care label. You see the price before you order.
