I can ride these in water dirt etc and they dont make noise for ballpark of 6 months

If you do this the grease inside the bearing which is likely in a more fluid state due to heat created by riding will leak right out of the bearing

Disclaimer this could damage your bearings if done incorrectly and zealous does not recommend you try to openclean your zealous bearings

Carefully open up the outer seal of your bearing using a box cutter or thin edge by gently prying the seal from the inner edge

Try not to scratch the seal

Note rubbing alcohol and citrus degreasers will not work ive tried

Posted by a reviewer on Amazon

The ar8300 contains silicates the alcohol and degreasers will indeed remove the grease but youll find chunks of silicate throughout your bearings and this is bad

Posted by a reviewer on Amazon

The bearings should each spin quite freely if all of the grease agents have been dissolved properly
