Really excellent product and it arrived very securely wrapped to prevent any spill or damage in transit. Restored my hunting trousers waterproofing like new.

Effective

I find the wash in method to be more effective, especially when the item allows for a low temperature tumble dry. It is nice that you could drip dry as well. Compared to the spray, which still serves a purpose, I find this distributed the water repellent nice and evenly. It brought the goretex jacket and DWR finished items back to like new quality.

Great beading!

I has to carry a box in the rain and got ink on my coat so washed it in grangers wash and then re-proofed it using this. Sadly not all the ink marks came out but generally the coat looks brighter, smells nice and seems better proofed than when it was new a few months ago. Have been out in the rain and the beading is great leaving me warm and dry.

Great for WPB fabrics and windbreaker fabric

Used this to restore water repellency on Patagonia Houdini (Ripstop, windbreaker), Salomon Bonatti (Pertex, WPB), and an old OR Rain Jacket (Pertex, WPB).The DWR product works great but there are a few details that aren't quite clear in the instruction:1. You need to prewash your garment using Granger Performance Wash.2. If you use the DWR liquid too little you won't get a good result, when I doubt, more is better. I used 2 caps (100ml) per jacket in a top loading washing machine.3. ~20 minutes of low heat inside a drying machine is recommended.

Great water proofer

The performance proofed is great when used in conjunction with Granger’s performance wash and repel. Prepare the clothing items, when dry spray this on and place the garment in the dryer on “proofing” and let it ‘set-off’. Water beads off nicely and the garment’s natural water proofing returns.

It works!

I just washed a few jackets and light rain pants (all DWR- not gortex) with a non scented detergent, rinsed very well and then washed all of them with this product, tumbled dry while still damp and then tried to spray on a water repellent. It just beaded up, as did a spray of water. I have now have worn the jacket in the rain and the water beaded up just like when the jacket was new. Easy to use- just follow the directions and it works.

My usual waterproofing for Gortex.

Have bought this Grangers for waterproofing all outdoor Gortex products. Only buy the waterproofing not the soap/waterproofing combined product because it saves money to use my own laundry soap from the Co-op.

Restores waterproofness, but beware of quantity

Product does restore waterproofness, my jacket starting beading water again after treatment. However, beware that if you treat only a single item the product only contains enough for two treatments (6 capfuls) according to the instructions, which recommend 3 cap-full (150ml) of product to treat a single product. They recommend an additional cap-full for each additional item so a single unit of the product would not give you more than 1 treatment for multiple items treated simultaneously. 2 bottles would give you 3 treatments of two items treated simultaneously with no product leftover. You can treat 4 items simultaneously with one entire bottle but three items won’t divide cleanly and you will have leftover product until you have used 5 bottles.Finally, be aware ... MoreProduct does restore waterproofness, my jacket starting beading water again after treatment.

For those you should use the spray on to treat the exterior only.

Worked like a charm!

My rain jacket was starting to feel heavy and damp on the inside when it got wet so I washed it using Grangers Performance wash and then put it through the machine using this Clothing Repel - now my jacket is beading water again just like it's supposed to do! Feels like new again!

Works - Expensive if using a top load washer

I have been using this product. It works well. The issue I have is it requires four capfuls if using a top load wash machine (directions do not specify HE machine or not). Four capfuls is a lot to treat one coat. That is, I am guessing, about a third to a quarter of the bottle. At twenty plus dollars Canadian this is pricey.
