How to clean this?

Anybody have tips or advice on getting the ugly stain out of this brake reservoir???

replace it?
i believe the dot 3/4 has leached into the plastic.
maybe scuff/bead blast and paint it as a last resort?

Throw a few bucks in the general direction of a parts vendor and get a new one.

You can get the "deluxe" package that includes a reservoir, cap and rebuild kit, too.

I had the same one and in about the same condition. Ended up finding one of the aluminum box style master cylinders and replaced it. There was a thread last summer in the brake section on where to get a new aluminum box type for about $50. Saw an old plastic one in a scrapyard on a bike that had been sitting for a while and it broke apart when I tried to remove the cap. That is what made me go to the aluminum box style as I figured the plastic had seen better days. Did not want it to suddenly give out a year or two down the road.

I think I will advise him to get a new one I found one on eBay for $15 so why bother with the old crappy one.

PM Sent, Terry. Thanks for asking

And regarding the OP question............. I have made cloudy / discolored / evil looking master cylinder reservoirs in auto and motorcycle applications look as good as new....at the worst, 9 out of 10, with Bleach. If the reservoir is intact and is not brittle because of sun damage....in other words....is still a safe piece, separate it from the master cylinder. Fill reservoir with water after adding a teaspoon or so of regular laundry bleach. No need to agitate. Couple of hours and I am thinking the reservoir pictured will be a thing of new beauty.

+1. Good results using this method, of course if you feel reservoir is brittle, best is to buy new.
