Overall Impression:
To me a car is not truly clean unless the glass is spotless. Bilt Hamber Trace-less is the best glass cleaner that I’ve found. Bilt-Hamber claims their surfactants leave nothing behind, meaning they evaporate 100% with no residue left behind that causes streaks. Bilt Hamber is an award-winning producer in the UK.
- Cleans well
- Resistant to streaking in direct sunlight
- Used for: Inside glass and show cars.
Tip for best results:
- For Extra Dirty Glass (Inside): Jay Leno’s trick is to use an all-purpose cleaner with blue shop towels to get most of the dirt off first. (I’ve found magic eraser works well too.) Then follow up with the Trace-Less glass cleaner as your final step.
- Finding Streaks: If you’ve had the experience of thoroughly cleaning the inside glass only to see all the streaks when the sun hits it in the morning, here is a trick: Head out to your car at night, place a lantern in the car, and you will definitely see any remaining streaks and missed spots to take care of.
