Grease is gone fast!

I picked up my new motorcycle and they had put chain lube that flung all over my rim. It was impossible to get off with soap & water, and bio-degreaser. The last non-bio degreaser took the shine off my last rim. This actually says to not use on paint, but I saw it used on rims in a YouTube video and didn't cause any issues. It cut through the grease in seconds and wiped off in one wipe. I was amazed. I chased it with soap and water quickly after just in case. Rims look brand new now and still glossy.

Works okay, not sure what it is.

The text description doesn't match the photo. Be careful, I ordered "Brake Cleaner" and I received "Electrical Contact Cleaner"- twice.<br /><br />The product did clean off some break dust, but can't help but feel that it's an electrical contact cleaner and not a true brake cleaner.
