I am reproofing an Isotex™ coat which somebody had previously laundered and destroyed its waterproof properties. I don't know what grade the fabric is, but it is probably not the lowest as the coat has two sets of zippers protected by an overlapping storm flap.
The manufacturer's website care instructions don't give much guidance.
Do I really need to reproof my garment?
Reproofing your garment on a regular basis enhances its technical performance. Every time the jacket is washed as directed on the care label, it should also be re-proofed. Use either Regatta Wash-in Reproofer or Regatta spray-on Reproofer.
I decided to use the wash-in treatment, not a spray. The instruction on the bottle says
Shake well and pour 75ml into conditioner compartment of the washing machine. Wash garment following manufacturer's guidelines.
and some more about tumble-drying and ironing, which I didn't do. The coat was spun and is hanging to dry; I'll turn it inside out when the outside is dry.
I plan to give the coat a second proofing treatment, but
- hand treat in a bucket
- start with dry fabric
- use just enough water plus reproofer to saturate the coat
- drip dry
- turn inside out to finish drying
Is this wrong, or am I overdoing this and need only to repeat the washing machine conditioner cycle? Or was the first step already enough?
I would appreciate any advice readers might have on the best course of action. I have read some of the previous questions:
