I installed this on
Porsche Boxster

Review
Drove around the other day, and got my convertible's top really dirty due to the dirt, dust and BIRD DROPPINGS. When I was back home, I went ahead to get something to clean my top up. Came across this Sonax Soft Top Cleaner, and this thing worked so great! My ugly top went for an extreme makeover to look like new in just a matter of minutes. Simple application and removal, along with cleaning all so very effectively.

What I like
Strong formula that cleans stains effectively, but gentle on the upholstery.

What I do not like
They bear a heavy price tag.
