I need to wash my waterproof coat without ruining the waterproofing
hopefully this is not a duplicate as I've searched for an answer on here before posting. I found this but there seems to be conflicting views on certain aspects of the question.
What I would like to know is how should I go about washing my waterproof coat? It's not GoreTex, but IsoTex (5000 on the waterproof scale). This will be the first time I have washed it, and I've had it about a year now. From reading other answers I assume I will need some sort of waterproofing agent to wash it with - are there different types for different materials and could anyone recommend a brand in the UK?
I'm also unsure about whether to tumble dry the coat or let it hang. I've seen comments claiming the tumble dryer will ruin the coat, and others saying it helps to reinforce the chemical outer layer. Can anyone confirm what the best method of drying the coat would be?
Lastly, I've seen plenty of waterproofing sprays in hiking shops before - are these any good/appropriate for use on a coat? Or are they just for re-applying lost waterproofing?
Thanks,

As stated, your first port of call should be the manufacturer's washing instructions
I'm not familiar with this fabric. A quick google of IsoTex basically shows it's Regatta waterproof fabric. Not much details on how it's made, etc. but it does state it has a Durable Water Repellent (DWR):
The DwR outer fabric reinforces the waterproof quality and helps the water to run off whilst adding to the garment's windproof performance.
If it's got a Hydrostatic Head of 5000 then it's not as waterproof as Gore-Tex. This, and looking at the types of coat its made into, and the price point for, etc. makes me think it's not got got a physical barrier like Gore-Tex (or if it does, it's not as sophisticated).
Bearing all the above in mind, you want a non-detergent cleaner. I always use NikWax Tech Wash. Regatta recommend their own brand, but well they would... I've always had good results with the NikWax one though. Don't use normal washing powder; that will reduce the effectiveness of the DWR.
I would definitely then apply a new DWR. From looking at similar fabrics and reading reviews, a good application of DWR is pretty essential to this coat; without it, it isn't going to stay waterproof for long.
I prefer a spray-on one as opposed to a wash-in one. It allows you to be more targeted in its application, i.e. only spray it on the outside where it's supposed to go.
Tumble drying will improve the DWR. DWR works by tiny microscopic spikes keeping the water from soaking in. Over time these spikes wear down. Tumble drying (heating) allows the chemicals to re-form these spikes. Will it ruin your coat? What does the label say? If it says do not tumble dry, then don't. If it says you can, it will help and is worth doing.

The following information is from Regatta Professional.
Question: How should I wash my Waterproof Garment?
Answer: Always follow the care symbols on the inner label when washing your jacket. It is advised that you use pure soap such as Regatta non-detergent Cleaner when washing your Regatta waterproof garment. Avoid use of biological washing powders or fabric conditioners as these may leave a residue that could affect the breathability of your garment and de-activate the water repellant finish.Question: How do I remove stains such as oil and grease?
Answer: Avoid using a commercial stain remover to erase stains, as the waterproof coating on your Regatta jacket is NOT resistant to chemicals. Treat your garment as directed on the care label. This method may not remove oil and grease, but using a stain-removing product or biological washing powder may cause your garment to degrade.Question: Do I really need to reproof my garment?
Answer: 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.Question: What is the life expectancy of a waterproof jacket?
Answer: Remember that all Regatta Isotex garments are guaranteed to be windproof, waterproof and breathable for 3 years. Given that you choose the correct garment for your activity and it is properly maintained, you should expect to enjoy your jacket long after its guarantee has expired.
