Been using the glass cleaner for 4 years and bike still looks mint. Yeah i only use it as a cleaner wipe down I rarely actually wash the bike with soap and water. The ammonia or whatever removes any residue bugs and grime so bike is clean clean after BUT that includes the wax over time. Its not a polish correct......still it cleans great even rubber on undertail. Then I polish with showroom shine and bike is:bling2::bling2:Glass cleaner will take off Your wax, and I wouldn't spray it on Your windscreen or any plastic personally.,.
