To keep your favourite Seasalt raincoat in tip-top condition, we suggest you wash it every now and then with Nikwax Tech Wash®. This helps renew your coat’s ability to repel water, and makes sure it stays breathable.

Nikwax Tech Wash® is an easy to use, environmentally friendly wash-in cleaner that’s been specially designed for waterproof clothing. Simply put your raincoat in your washing machine, pop some of this in the detergent drawer, and wash at 30°C.

Unfortunately we are unable to deliver this product internationally.

Every few washes, follow with another cycle using Nikwax TX Direct® Wash to restore the waterproof finish

Excellent Product

Used this to clean my Seasalt winter waterproof before putting away for summer. Not a make left on it.

This is fantastic stuff.
I was so disappointed when my 100% waterproof coat wasn’t anymore 😫
So I bought both the wash liquid and the proofer.
So easy to use. Just put a capful in the wash dispenser of the machine. Twice if using both products. Hang it up to dry and hey presto - the rain runs off in beads - fantastic !
Only disappointment - I had to iron the coat and I hate ironing !!!

Worth every penny!

Surpassed my expectations. Used on my Janelle coat and it looks brand new. Plus there’s enough for three-four washes. Brilliant, great product.

Janelle coat/ Nikwax

My coat came out like new. Very pleased with the Nikwax and would highly recommend it. Would not use anything else.

Great results

My 6 year old Janelle coat looks brand new again after a good wash! I would highly recommend both the Tech Wash and the TX Direct Wash.

Good results

I used this product to wash my Seasalt coat and am very pleased with the result. The coat looks clean and has a lovely shine and soft feel. I did close the zip and fastened the studs.

What am I doing wrong?

I bought this to clean my yellow seafolly coat and it has literally done nothing? Still has loads of dark marks and generally still grubby.

I washed my sunny yellow sea salt jacket yesterday with your wash and it looks good today. Only thing I would suggest is to close the zip while washing as it’s slightly wavy this morning. Will now get my blue winter sea salt jacket out!

Have only used this once so far on two garments at the same time. Seems to have worked ok. Will use again next time I wash my lovely blue coat. Does not seem to effect the colour at all.

Was recommended to me

Although I haven't used this yet, it was recommended to me by a friend. It does make sense to use this with my Seasalt waterproof jacket.

Tech-washing my mac

An excellent product. Very easy to use in the washing machine and the mac looked like new afterwards.

Does what it says!

Hate the lid for measuring, but the product worked a treat and got all the grime and smells off the coats. Must try the re-proofing next.

An excellent product

This does exactly what it says on the tin. I have an old Seasalt Gilet which I keep specifically for walking my dogs. When washed in this product (and followed by the re-proofing as recommended), it came up like new. An excellent product.
