Hi all,
Though I'd share my experience as I did hours and hours of research to see how to clean a convertible canvass Audi roof on my A4 cabriolet. My problem is, I had mold so bad..nothing, and I mean nothing seemed to have removed the mold.
I promise you, all roof cleaners are utter bo**ocks! They simply did not work as there is no proven 'science' to clean a roof as so many companies claim.
What I did which worked to PERFECTION is;
1. Rinse the car and roof with a pressure washer.
2. Add 'Miltons' baby sterilizer fluid to a bucket. Use the instructions of what ratios etc. You can be generous with the sterilizing fluid as it wont bleach or change your roof colour.
3. Take a bristle brush, but the soft one used for household washing and scrub the solution into the roof. Its a lot of elbow grease involved to cover the whole roof but you should see the mildew being penetrated.
4. Leave to soak for like 30mins or so.
5. Pressure washer time. Get a ladder, and take the pressure washer, spraying the roof section by section keeping the nozzle of the pressure washer VERY close to the roof. Im talking just 5-10cm away. By doing this you will literally be going back and forth 30 odd times but you will see how effective this is as you will see 'clean' lines as you do it.
6. After the whole roof is done, wash the car and hood with a microfiber cloth. Then Pat dry the roof with a cloth that doesn't leave material on it.
The Results;
My Roof looked BRAND NEW! Oh and...my roof is navy blue so dont worry about colour fade or anything similar.
Other things to point out..
A - Your roof wont leak if its closed properly. Mine didn't even in the nooks and crannies.
B - You must use a pressure washer and...very close to the roof it it was as stubborn as mine!
Hope this helps..
