| Why it was picked | Two litres, two stages, roughly ten garments before the TX.Direct runs out. (Best waterproofing sprays and wash-in reproofers) | One bottle, one wash, clean and reproofed at the end of it. You add two 50ml capfuls per garment to the machine and the job is done in a single cycle instead of two, which is the whole point of it. At three garments a bottle it is the cheapest way in if you only have one coat to sort out. (Best waterproofing sprays and wash-in reproofers) | A tent flysheet or a caravan awning is square metres of fabric, and a litre of concentrate does the job of six little bottles. (Best waterproofing sprays and wash-in reproofers) | Sometimes only the shoulders and the forearms have given up, and the rest of the coat is fine.

| What to know | Not recorded yet | The catch: the label says heat activation is required, so you have to tumble dry it on low or go over it with an iron or a hairdryer. | Not recorded yet | Not recorded yet |

Look Into researches products from published sources: makers’ pages, retailer listings and regulators. We have not handled or tested these products, and a blank field means we have not recorded that figure yet, not that the product lacks the feature. Awards are Look Into editorial picks, not Amazon or third-party awards. As an Amazon Associate, Look Into earns from qualifying purchases; commission never decides a ranking.
