S-Doc100 visor and helmet cleaner, £12.95
Time used: One month
What’s good? It’s extremely easy to use. Spray on. Wipe off. Done. The microfiber cloth comes in handy for other things such as cleaning my specs and computer monitors. It’s small enough to fit under your seat or in your pocket – so comes in handy when you don’t have time to soak your visor for a couple of hours.
What’s not? Leaving soaked kitchen roll on your visor works just as well, if not better in some cases. For such a small bottle, I think the price is a bit steep.
