For the benefit of other readers: On the forum we welcome input from the trade as they can often provide helpful knowledge or advice, but we ask that they are transparent about who they are (or if they want to remain anonymous and not talk about their products or services then that's fine too of course).

The forum T&Cs state, "No Trade or business advertising – except bona fide retailers may respond to genuine enquiries from potential customers."

Hope that helps.

I always try to avoid recommending one product over another though -- we all have preferences and of course some people are going to prefer one product over another!

I just think that it's important for everybody to have all the information about products/brands they can get! It just makes it easier to make the right decisions for our kit (and as a cyclist myself, I know that kit is sacred! Would be lost without my Rapha gear!).

Hope my advice is welcome (and let me know if not). :)

Looking at their website, some products require heat and some don't.

Grangers do both wash-in and spray-on products, and only one needs heat.

Again though, lots of people saying Grangers is heat-activated and it definitely isn't! The Performance Repel spray and Clothing Repel wash-in work perfectly if air-dried.

I've used the Grangers 2-in-1 quite a lot and it has always worked well.

do tumble dry to finish and the clothing then beads well. I use one of those bags to put the stuff in to tumble dry as it seems to beat the stuff up less.
