Just buy this.I have a 2007 convertible with the original cloth top. It has only been garaged intermittently, parked under several trees, and the age and abuse were showing badly. The light dirty spots seemed permanently stained into the originally black fabric. I had tried other well known and recommend brands without success so I was very hesitant to spend another $54 on this but I am so happy that I did. This worked.I used the cleaner on a dry, moderately “clean” top, no pre-rinse or wash. I went to town and used a solid 70% of the cleaner on the first (and so far only) application. This did involve a lot of scrubbing but that is purely because mine was so far gone. I found the brush great at working the cleaner into the fabric while also being gentle, but it was an awkward shape/size for my smaller hand and made the work feel harder than it was. If scents/fumes bother you, this gave off nothing that I could notice outside.I followed the scrubbing up with the pressure washer, using a fan spray on the cloth until no residue was coming up in the water and let it dry in the sun. I was blown away by the results. Truthfully I expected another let down, I didn’t even take a before photo because I didn’t see the point, but I cannot stop staring at my top in amazement. It hasn’t looked this clean in years. It restored what looked like a dull charcoal gray top to a clean black sheen top.I have not used the protectant spray yet. I plan to do one more go with the cleaner to see if that will take my top any further or not.Attached, I found a before photo that just happened to show my old gross top, a second photo from right after the clean, scrub, and rinse when it was about 90% dry, and a third from the day after where you can see how little discoloration is still there.
