Nice one, cheers, but for what it's worth I'll stick to what I've always done as I have never had to replace a chain due to my own negligence as I have alway bought my bikes used until now.
However, I think that so long as you keep your chain in good order and try to keep the gunk to a minimum so it doesn't turn into a grinding paste then so what? A chain is a consumable and if I need to change one after 3 - 5 years of use then it's no big deal, but my mileage is not huge so I'd expect it to probably last 10 years. Keep it clean and keep it lubed. Simple. If a product MAY wash out the factory grease then it stands to reason that other products with lubricating properties will flow to maintain some sort of protection. Maybe it's a case of trying to balance up the ones which compliment each other?
Haha, I suppose, although after doing a little search on eBay I found a twin pack 2x750ml of IPone cleaner and lube with a chain cleaning brush for £19.99 or around $26 at M&P which is a Motorcycle and motorcycle parts emporium we have in the UK.
My main problem would be to find it in Finland, or find someone who delivers to Finland without asking a hand and my forst born child for shipping fees
Ill keep an eye out for any of the products that passed.
As for the brush, i dont trust the stiffness of those brushes to not mess up my o-rings. I just use any old (soft bristle) toothbrush i have. It it doesnt harm my teeth and gums, it wont hurt my o-rings either
