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.

Nikwax Tec Eadh

Used this to wash and re waterproof two Saltrock coats, I found one bottle was the correct amount to wash two coats, although I did wash them separately. Came out looking fine and smelling good.

Not Used Yet - Just received!

As I have only just received this product and have not used it yet, I cannot comment on its performance. However, Sea Salt has been more than accommodating during the covid19 period as I was unable to collect in the given time including an extended period but Sea Salt refunded my items and I was then able to reorder and have it posted to my address. All at my costs obviously but thank you Sea Salt for keeping my items in my selected store for an extended period.

Worth every penny

I bought this with my Coverack coat for future use but decided to try it out on a waterproof jacket which had not been washed for a while! Brought the coat back to life, smelled fresh and is still waterproof.

Brilliant Product

I used this product after I had washed my Seasalt coat (using TX Direct Wash In.) I have had many walks with my dog in very wet weather and I am delighted to say that my previously leaking coat is now water tight again. Very pleased.

Jacket looks like new again
I thought at first it was expensive so put off buying but considering the price of the jacket it just means I’m getting extra wear especially as I used the wax treatment as well

Works like a dream

Really Impressed, my yellow seasalt coat had gotten very grubby after a whole season of wearing it. As instructed i rubbed some of the solution into the grubby areas, and then washed as instructed.

Worked brilliantly, removed all of the grubbiness and even a biro pen mark ! Smelt kinda of funny when drying quite chemically, but now that it is dry does not have an odour.

My coats look good.

Washed two coats in this solution before re-proofing them. I am very happy with the results and the ease of use.

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.
