Question: How will the NikWax Cotton Proof affect the synthetic fiber-fill lining of a Carhartt cotton jacket?
Document: Nikwax Cotton Proof...9 years on and my jacket still sheds water. I bought a bottle when I was going to college and had to walk in the rain many times. I spent too much money on pricey "waterproof" parkas (Columbia, Solstice) only to find that my shoulders would be wet after a long march in a heavy downpour.
I've now used up most of the bottle on various garments with extremely mixed results. On some cotton rip-stop pants and a hat, it worked a treat; on another cotton jacket with a coarser weave, it had absolutely no effect whatsoever on the outside (the lining beaded up nicely after treatment).
I wanted to waterproof a 6' x 9' cotton canvas dropcloth so purchased the Nikwax Cotton Proof. I used in the washing machine as instructed, dried the canvas, and it's no more waterproof now than it was before I treated it.And of course Nikwax doesn't have an e-mail address for complaints, and the phone is available only 8-5 M-F...when I'm at work and can't call.Don't waste your money.
I've used this to periodically waterproof my boat cover now for 3 seasons. I start by washing it with an appropriate amount of Nikwax Tech Wash (usually 30-40 ounces) and then wash it again with the Nikwax Cotton Proof (again 30-40 ounces added at 2 different times - 20 ounces right away and 20 ounces after the prewash is done). It keeps the boat cover water resistant all summer, even in the harsh Texas sun.
I used this to retreat my Carhartt jacket and it works just fine. The alternative is a very smelly silicone spray that is quite expensive, stinks, and really doesn't last that long.I don't know why the reviewer that did the machine wash didn't have success.I will definitely use as long as it's available!
I've read reviews that talk about a smell or a change in the look of the garment. My experience couldn't have been any different. The secret is the FOLLOW THE DIRECTIONS EXACTLY. You must make sure that there is no detergent residue in your washing machine before you use it. I ran an empty load to rinse out the machine first.When I used it on my Carhartt jacket, it worked exactly as advertised. There was no smell and no residue.
I doubted that this stuff would work! I used it on a cotton/poly blend messenger bag and on my cotton bike rack bags- works very well! Not water proof, but very water resistant!
This is a preliminary review since I haven't received the correct product yet. What I got was the wax cotton spray, meant for previously treated cotton items. Yes, similar but definitely not the same. Reading other reviews it seems that Amazon has trouble shipping the correct item.As of right now the wax cotton spray has been returned and I'm waiting for the cotton proof.
always doubtful  i tried it  and messed up the directions a lot and it stll...worked GREAT  soft cotton M-65 jacket was waterproof!!! and warm  and the scent of the product was gone quick yet the material stayed waterproof even in Alaska rain. quite happy!
I bought this to waterproof a cotton jacket to wear to Iceland, where weather is unpredictable and can require a raincoat at a moment's notice. I couldn't find a cute raincoat, so I just decided to waterproof a jacket I had instead. Works like a charm. I stayed warm and dry.
Answer: yes
