I purchased a 'used' Hy-Road to experiment with. I really like the ball's performance but noticed that wherever I bowl, this ball picks up gunk from the pit :-)

Not only does it pick up gunk, but normal cleaning agents hardly touch these smears. I use Power House ball cleaner, but I may as well be using water.

I polished my Hy-Road hoping it would help, but no joy. Anybody have the same ball and problem? What do you clean it with?

I have a Hy-Road, at a 2k dull surface and haven't noticed that is any worse than any other ball, as far as picking up gunk. I use nothing but 90% rubbing alcohol on my stuff - cheap at a drug or dollar store, and I am good with the results I get with it. I clean my junk (so to speak) after the session it got used on, before packing up to leave. NOTE: rubbing alcohol is one of the few things that it is legal to use AT ANY TIME. A lot of other preparations are restricted to use only between session or not at all. The USBC website has a page that lists commercial or industrial solvents and their legal status. For instance, MEK and acetone are banned entirely, as they effect the chemical composition of the ball surface.
Good luck, and let us know what your solution was!

I have two Hy-Roads. My guess is that since they're shiny almost black polished balls, that you're seeing much of what you're getting on all of your equipment. It's just that you don't notice it as much.
At the house I normally bowl at I have no issue with dirt or grime; however, if I go to three other houses near me, they're all quite dirty especially from the ball returns.
As for me I use a mixture of LA's Awesome degreaser (one part) and alcohol (three to four parts). Get them at the dollar store. Also, use a shammy between shots. Use Storm's Reacta Shine on them as well. Shine them up after 9 games or more. The Reacta Shine has some grit in it which cleans up belt marks and such.
Hope this helps...

Like all bowlers, I'm use to getting all kinds of smudges on my equipment. I've just never owned a ball that collects so much grime so quickly and I've never had so much trouble removing that grime. I also have 2 Storm 'Locks' that I used during the same sessions and neither collected any dirt. That's why I thought my problem was ball related. The Hy-Road is much more tacky on the surface than the 'Locks'.

Searched the internet and found a number of complaints about the R2S cover stock collecting grime. I guess the tackier a surface is, the more grime it picks up.

I didn't look it up, but going by memory, the Lock ball is a matte finish solid coverstock ball, isn't it? You have it listed as polished. I wonder what polish you're using on it.
The Hy-Road is a hybrid and I believe they use Step 2 compound to yield what they call a 1500 grit finish.
I've used Powerhouse's Clean n'Sheen on my Hy-Road and it works about as well as Reacta Shine. What ever polish you use on the Hy-Road, I'd recommend a company's factory finish unless you'd like to have the Hy-Road go longer down the lane for you.
Good luck...

I polish all my balls to keep them from soaking up too much oil. I usually use Extender Polish. It also helps me keep my RPM's up and keeps the back-ends from jumping.

When I clean balls, I use paper towels. That really shows the dirt from the surface that got removed. It is also the recommended way to clean, as listed on many cleaner bottles.

I only bought a Hyroad back in June so I am kind of still experimenting. I used the recommended ReactaShine to clean and polish but I did not like the resulting effect. The ball was pushing too far down the lane not getting into a roll and lane motion I desire. I knocked off the shine and tried 4000 grit. Only problem the next week of bowling the lanes was screwed not the normal house shot to compare to. But at 4000 I was able to play line that resulted in a little success. Posting to state Reacta Shine as a cleaner between sessions may not be a good option for all bowlers especially ones with a little speed.

To clean my Hy-Road I will use a cleaner that my Pro Shop has. Must be a generic licensed to companies. I believe Buddies sales it also but a get from my local Pro Shop. A little support there for my local PS. The Hy-Road does seem to pick additional stuff almost like plastic or something from hitting the pins. Now I have taken my surface to 500,4000 the next step as in the video on the Storm | Code Red Surface Adjustments. Figured this applies to the Hy-Road too.

Sorry to hear that you didn't care much for Reacta Shine. I haven't tried other factory polishes like from Brunswick or Ebonite, but I've used Clean n'Sheen from Ebonite and it's similar.
I just put some Reacta Shine on my Code Black this morning. I haven't polished it up in a while and thought I'd give it a try. Just used a small piece of an old tee shirt with a little dampness on it. Used a swiggle of polish on three different parts on the ball and it took me a few minutes to get it all done. Looks and feels great. Hope it works well now, too.
