Just wanted to let everyone know that I bought both the house and car kit, and it works great!
The day I bought it, I came back home and decided to clean the car inside out. So I tried the car kit, and man! My dashboard came out looking brand spanking new!
Then, I tried the home kit on a few dusty LEGO pieces, and again, I was amazed how well this product works! All my pieces came out looking brand new (those that were just dusty, mind you. Those with scratches just came out looking really clean.)
As for « cleaning the Cyber Clean », obviously, you can't. You just fold it a few times and the dust just gets trap in it. That means that it will eventually be too dirty to be used. To give you an idea, my dashboard was really dusty, yet I think that my tub of Cyber Clean will still be good for another 2 or 3 clean-ups.
Anyway, I really recommend this product, especially since it's so cheap to get (I paid $6.97 CND at my local Zellers for each tub I got.)
You'll find it near the autocare aisle (both car and home kits).
