Great cleaner, smells nice!
Scent: Lemon
I use half a bottle and mix with water--great all-purpose cleaner and it doesn't have a horrible chemical scent. It smells nice and cleans well. I buy this on a subscription.

Prices right cleans well

Cleans well in my power mop but if you use too much it leaves foam on the floor. Use sparingly...

I am extremely satisfied with this product! It worked even better than I expected. The plastic on my car looks like new again—deep, rich color and a nice clean finish. The application process was simple and quick, and a little product goes a long way.
I also love how long-lasting the results are. After several washes, it still looks great and provides solid protection. Definitely a high-quality product that delivers on its promises.
I highly recommend it 100% to anyone looking to restore and protect their car’s plastic surfaces!
