Get yourself an Autoglym hood cleaner and proofer kit (approx £20). You might need 2 applications of the cleaner if the hood is very mouldy.

Enjoy :wink:

The Autoglym proofer is both good in that it really does protect your roof for a long time, and bad that it prevents you from re-dyeing the roof if the colour starts to fade.

If you think the roof needs a dye treatment, do this after the washing, but before the proofer, or be prepared to wait in excess of a year for the proofer to wear off.

Can vouch for the Autoglym kit, did of good job of cleaning the roof and the proofer is great, water just rolls off. Word of caution when applying the proofer, make sure the rest of the car is covered before spraying it on as once it drys on the glass and bodywork its a complete pain to remove.

Hi Matchy,

I've had the same problem with my hood this year :head:
On previous occasions I have used the Autoglym Hood Kit and it's worked a treat, but not this year. I've actually spot treated the said green bits at least 4 times and nothing seems to be shifting it. The rest of the hood is sparkly clean apart from the few patches on top and what seems to be a line at the very front of the hood.
I feel reluctant to use the renovo black, only because I quite like the stitching contrasting (a tiny detail I know) with the hood. :nerd:

Try BMWs own hood cleaner and re-proofer worked wonders on my roof. I got a bucket of green water from mine. Costs £26 20 for the two.

Thanks for the replies , I have used the BMW roof cleaner and impregnating fluid , usually with good results but this year I just can't shift this " green stuff " ! ... I am now going over it with a brush and water , using the cleaner creates a foam that prevents you seeing the mould . cheers .

Water and brush will not shift it alone. You will need to get some Autoglym or the BMW stuff for a good result.

As for rubber components? I have tried for the past year to fix the seals where the roof meets the windscreen, to no avail, and have had to resort to using petroleum jelly to seal it properly. If I didn't use it, the usual sign first thing in the morning was to find a wet floor and seat. I went and ordered a spray can of the new gummi pflege (rubber care in english) from BMW, sprayed it on a rag, and applied it four or five times along all the rubber seals.

Problem solved :D

when i first got my Zed it had green stuff round the roof near the the bodywork, when i washed the car i just went round the foor woth a damp sponge and let it dry. Since then regular use has kept it away .

Matchy I had this same problem and after a long search and many tries i found something that really worked for me. I also tried just water and brush just like dalboy suggested but with no results and I wasted so much time. If you still need an advice my convertible top looks like new after i cleaned up using Autoglym Fabric Hood Maintenance Kit. It's not cheap, but it's effective.There's a Fabric Roof Cleaner kit - cleaner plus sponge-thingy. And then, to prevent future problems, a Fabric Roof Protector. You could do a small test area first. Hope this is of use to you.

The meguiars hood cleaner seems to be much better than the autoglym. You work it in with a nail brush or similar. Then wash it off. It seems to remove more of the green. Then I treat it with either autoglym hood treater or the meguiars version.

If it is still green then hood dye is the best bet. I just paint on some more over the green bits and blend in. I use a small artists paint brush. It's lethal stuff as it always dribbles somewhere it shouldn't. You have to wipe it off with a damp cloth within milliseconds or it won't come off ever.

Can't beat renovo, cleaner, dye and proofer, even comes with a polish for the plastic window.

I've just had a new rear window put in and while I was there the intention was to steam clean the roof as well as he said it was the only type of cleaning required.

For technical reasons he couldn't do the whole roof. But he demo'd how to do it properly on the front half. Note you don't just point and shoot. There's a whole method associated with it to do it properly and in-particular not destroy the stitching.

My misfortune in not being able to have the whole roof done is everyone else's gain as it shows you before and after. The cleaned section came up literally like brand new. Absolutely pristine and jet black.

No further treatment required. No dye needed as it's jet black now. And no waterproofer needed as there is a second skin on the inside - evidenced by no leakage even with 80 deg steam hitting it. He dislikes Renovo and all treatment products.

The only downside is steam cleaning will exploit any leaks you have around the window.

Anyway, here's the pic.

Image

The cost for the clean is £30. The specialist is Tony at Soft Tops in Coventry. He's been doing soft tops for nearly 30 years so he certainly knows his stuff.

And here's the rear window. Immaculate job. Tony re-uses the existing zip and sews a new piece of vinyl in. Much nicer than having a stitched window. This job is £130 normally. My roof and stitching is structurally well past its best though (even if it looks nice in the first pic) and the job ended up quite complicated. So I did pay more than this in the end. But it was worth it.

The roof looks really good and the price seems very reasonable. I have (well Mrs ZC has) a steam cleaner so any tips on the technique? I was thinking of cleaning along the surface rather than down on to the roof, a bit like using the power washer.

Keep going and you'll have a great looking Zed.

You need an industrial steam cleaner not a domestic one (sorry). They cost £100+ to hire for a day. So arguably this is not a DIY job unless you know someone with such a beast. You'll only tickle it with a domestic cleaner. An industrial cleaner runs around 100 bar and to put things in perspective a domestic one runs at 3-4 bar.

I'm sure Tony would prefer you to go and see him and I don't think £30 is expensive to get it done right without damaging it. But the single most important thing is not to wreck your stitching. Run the fan from the lance with the stitching and not across it. You could weaken the stitching or rip it out otherwise. It's fine if you follow the line.

Other than that I just have a mental image of the size of the fan from the lance and distance from the roof which is difficult to articulate. But go in gradually to find the optimum distance.

Other excellent soft top specialists are available but whether they all have a steam cleaner and know how to use it properly I don't know. I would certainly avoid someone who happens to have a steam cleaner and stick with a soft top expert. And definitely don't cold water pressure wash.

I was also advised one of the key ways to tell if your roof is knackered.

If the line of the roof arches over the middle of the doors and in particular if it starts revealing the rubber door seal then the roof has shrunk across its width.

The door rubber is not the first/only line of defence against water ingress. It should be the roof. For this to happen the roof has to come down as far as the lower edge of the door rubber. When Tony builds new roofs he builds a little extra overlap in so the roof comes down just below the line of the door rubber.

And one final thing. New roofs can be had for as little as £280 I think I was quoted by one specialist.

Tony is by no means expensive but his charge is 2-3 times that. And there's a reason for it...

I've seen one of these cheap roofs fitted. The material looked cheap and shiney (synthetic) and certainly wasn't canvas OEM spec. It wasn't double skin and it had a stitched in rear window.

I haven't see one of Tony's roofs but I would expect the price to reflect having one built to OEM spec.

My roof looked like the one above until I followed an online tip and used Milton fluid diluted 1 part to 5 parts hot water and then worked in with a scrubbing brush. I then used diluted Johnsons baby bath to clean it afterwards and then about three coats of waterproofer. I have a jet black, clean and waterproof hood now :D

I blast my roof with the pressure washer every time I clean the car, Snow foam then 140 bar. No green mould in sight.
Obviously its a fan spray and not at 90 degrees, My roof has been on 3 years now with no mould and no leaks and no treatment. and it gets washed very regularly! and my wifes is still original roof.
Been pressure washing soft tops for 8 years without an issue
besides the steamed part doesn't seen to be doing the stitching much good.

stop being big girls... :D
