Cleaning a cabriolet roof

**hanny73** · 24-03-2009,10:38 PM

Hi all,

I've got an A4 cab with a blue roof, can anyone reccomend a cleaning agent to remove the mildew.

I've read that Renovo are a good brand, any ideas which one I need to buy?

Thanks!

I have not tried Renovo yet. I'm using Autoglym. My roof has never had mildew so I don't know how it works on that,but I clean the roof 3 times last year and it stayed good through out. A part from the 3 times I cleaned it I never touched it otherwise.

Renovo all the way, they are the only brand I would use on the roof and I did a lot of research before using them for the first time (8 years ago). Note it is expensive but so is the roof and you only do it twice a year.

Had a saab 900 convertible for years and now have an a4 convertible and twice a year would clean the roof - first use the canvas cleaner - it works great,

Then use the Soft top reviver - they do it in blue - this stuff is amazing and makes the roof look like new. My

then finish with ultraproofer and you have a roof ready for 6 months of use.

The only thing is that each step must be finished on the same day and I would recommend washing in the morning, let it dry and then paint it so no new dirt has got in. You could leave it overnight but I wouldn't drive it until it is painted (like waxing a car really).

Ultraproofing can be done later without any issue.

Regards,

Walter.
