I dont use my cbr as much in the winter, so tends to stand for prolonged periods, and when I do use it, the weather is usually damp. How can you stop surface corrosion on discs happening when u put it back in the garage? is there anything you can put on them to stop it? Even after washing, unless u can for a blast and dry them out, you always get the corrosion come back. Any Ideas?
You cant really stop it unless you run a dehumidifier in your garage to dry it out ! couple of touches of the brakes they will be shiny again anyway !
Happens to cars as well - but you can’t see the discs so you don’t worry.
Wotmeworry etc… 
not alot you can do im afraid , sounds like u may have aftermarket discs with a higher iron content as honda OE discs are stainless rotors
PFM discs rust up like mad within 20 mins of damp , must be made by kawasaki
If it really irks you, then wire wool would remove it, but gentle - don’t want to score the discs
But best solution is always…
go for a ride!!!
I use the biggest longest cover so the thing drags on the floor to stop the damp getting under it. You nearly always get some kind of moisture around, it’s the devil 
funny enough we were talking about this yesterday, its not just the discs with mine but the cheap bolts that a dealer fitted to them when she had new discs.
Cheap stuff!! On your bike!! How very dare you! 
yes cheap an i DONT go together! ha ha, they are being replaced!!!
Yeah, my Sackakrapi is 6 months old, never seen rain (lol) and the discs and bolts are rusty and furry, despite the use of ACF-50.
the fazer is going in for her major service this weekend and is having the bolts replaced.
You wont score the discs with wire wool, no matter how vigorous you rub them with it, considering that when you replace brake pads you should deglaze the discs with emery cloth/sand paper, wire wool wont cause any harm.
i think i might put a set of wavy galfer discs on.
If you must leave you bike sitting doing nothing for a long while I would buy a decent bike like an cover Oxford Stormex but before covering it, strip your bike of her fairings and ACF-50 the engine, down pipes, under the seat etc and Scotoiler the parts that can’t be ACF-50 you could scottoil your brake disks to just remember to clean it off before taking it for a spin in the summer Motel do good brake disk cleaner.
Hope it helps

Please explain this?
Which bit???
Why you need to deglaze brake discs and how you do it with emery paper?
It was always considered good practice to clean the surface of the disc to remove any previous pad deposits and contamination. Done by rubbing the disc surface with medium/coarse abrasive paper in the direction of the grain. Allows the new pad to achieve better contact with the grain of the old, unrenewed disc surface.
As many high performance friction materials impart a friction transfer layer on the disc surface, this should be cleaned away when new pads are fitted.
This is especially the case when a change of compound is made.
But this practice is rarely carried out by garages. But its one of the things I was taught years ago as a young appretice and have just continued to do whenever I do a brake job.
Same here
Nice to see I’m not the only one who still does it then!
