Dirtwash G-strings and Bike Cleaner Spray (Angus Fyffe)
The bike cleaner does a great job, most of the time I used it for cleaning the chain and cassette as it is a great degreaser. It really did remove all the grime that builds up on the road bike chain. The only downside is that it runs out too fast haha, but on a serious note I would definitely buy it as a degreaser. No complaints.
For the G-strings, to be honest I didn't find them of any great use. I did try to use them in the cassette but was a time consuming and that didn't really do the job as well as other methods, however one use I found them to be great was removing crud between the bash guard and chainring which has always been an annoying problem.
