Works well, but...

Just does not seem to go very far.<br /><br />Sprayer is of good quality, wash itself goes on easily and rinses completely with no residue (even when spraying it on before cooling sufficiently). It even smells good. But I also found that it did not cut the grime that always collects on the lower fairings and so I had to reapply and basically wash twice to get everything clean.<br /><br />It basically seems to lean toward the mild side. I don't think you would ever have to worry about it damaging paint or decals or anything else and that may be a big plus on a rare or vintage ride that may be damaged by more aggressive solvents in some cleaners.

Great product!

Works amazing...I like to rinse down the bike spray this around all areas and just watch the dirt fall away for a few minutes. Then you just need a quick wipe and a spray and everything is new. I’ll be buying this product until the day I die. You should too

Awesome Cleaner

This cleaner is amazing. I have powder coated white rims on my GSXR and this cleaner helps wipe of the grease that gets all over them. It smells good, and is super mild so I don't really worry about it damaging any of the plastics or anything like that. Will def buy this again.

Buy it, its a damn good product!

Honestly the best cleaning solution ive ever used. Cleaned up 7 year of grime and brake dust from my wheels, took off all oils and residues from my frame, swing arm and pegs. Even got all the dead bugs from this spring, best of all is no water spots at all. Some areas needed two applications but it was super easy. This stuff and a nice soft towel did the job 1000%

Bio-Wash

Good stuff, but not for mirrors. It streaks a lot. So make sure you dry and give a slight buff

Excellent spray cleaner!

This imo is more of a spray cleaner that you apply and manually wipe areas. Using it this way this stuff is pretty amazing! Bugs that explode on the front end usually ain’t easy to always get off. When cleaning if use my finger nail and stubborn spots and even that doesn’t always work! This stuff takes it right off with ease! Spray it on the rag so it doesn’t run and buff it right off! The only down side is the cleaner leaves things streaky unless you flip the rag and keep buffing out the spot. I always wax after so this is no issue to me. This stuff smells great and it’s priced right! I’ll be using this exclusively from now on! Works excellent on wind screens too just remember it tends to leave streaks so use a clean rag to buff the streaks out.
