Cleaning roof

[Acestumacher]

Have a look at Car Cleaning Guru on YouTube - he recently cleaned the roof of a MX5, which was in very poor condition.

My nephew asked me about that video as he's just bought himself an MX5.
OMFG, major cringe with the amount of scrubbing he did on that roof!!
He's probably taken at least 10 years out of it's life! It's amazing he didn't wear holes into it!
My nephew followed my (and his granddad's) method to tackle the mould on his own roof. It took over a week of applying and re-applying white vinegar, letting it soak in and do it's own work before lightly washing and it's come up like brand new!

As an impatient Gen z'er he wanted an instant result but wisely he decided to bide his time and is now glad he did.
You can also make your own vinegar solution by mixing acetic acid with distilled or demineralised water.
It's the ONLY method you need to use unless of course, you're an impatient sod.

yes think I have been that impatient sod!

There is no doubt white vinegar is a tremendous cleaning product. However, the various companies supplying bespoke cleaning products argue that vinegar or milton tablets may very well deal with the green stuff on a convertible top, but that their products also contain inhibitors to prevent regrowth. It is also interesting that these same companies all sell brushes to scrub the fabric. I tend to the view the fabric used for convertible tops is pretty tough and I have used these brushes regularly over the last few years with no apparent damage.

It's amazing though that we all have slightly different approaches to cleaning the roof...
