“I have removed the mould from my Saab convertible hood, but white marks have been left afterwards!”

This is a very common issue that convertible owners find, in fact, these marks are often mistaken to be left over mould, which the customer will continue to scrub to no avail.

From years of experience with soft tops, and despite the absence of a photograph, I am confident that the marks present on the top after cleaning are in fact damage known as “scarring“. This occurs when the top has been allowed to be so badly ingrained with mould, that it has taken root within the membrane and caused permanent damage to the top. Then once the top is thoroughly cleaned, and mould is removed, it then leaves the scarring behind, which unfortunately is not removable.

I can only recommend that you have another go at cleaning the top to the best of your ability using these instructions:

Mist spray the top and then paint on Fabric Soft Top Cleaner leave the solution to process for approximately one hour, the optimum time for the active ingredients to work. Using hand hot water the surface should then be scrubbed with a bristle brush, being careful around stitched areas. It is essential to use hand hot water. Finish by rinsing off with water. Repeat the whole process as necessary.

You could then try to improve the marks by applying the Soft Top Reviver to the whole top, which could help mask the scarring; however, I will advise you that this may not completely remove the marks from sight, but it will certainly make an improvement.

If you do wish to apply Soft Top Reviver, remember it is imperative to check that all previously applied proofing agents have been removed during the cleaning process! To expedite this you can simulate a shower of rain (not a soaking) with a rose attachment on a watering can. If the sprinkling of water from the watering can soaks in evenly all over then so will Reviver, as it is a water-based product.

When you are sure that you have removed all previously applied Proofer you can start to apply fresh Reviver in order to help mask these marks, unfortunately, the Reviver may not thoroughly mask these marks, but should be of some improvement. We recommend applying at least 2 coats but no more than three to the whole top! You will then need to apply Ultra Proofer to keep the top protected from being ingrained with dirt any further.
