21 year old convertible hood with ingrained moss

[OldGermanHeaps]

I have tried scrubbing, g101, hot water, pressure washer on low setting, dont want to use high as it will wreck it.
The moss just wont shift.
The hood is in otherwise good condition.
Dye kit ?
Any other suggestions?

I have just done an almost identical hood on Mrs NDA's Audi. Came up like new.

Follow the instructions and it's an easy job.

You'll need a decent brush

And then waterproofing

Try milton sterilising tabs dilured and left on for 30 minutes…rinsed off then apc scrubbed with a soft brush repeat x3

use hot water and laundry liquid with a brush. Then re proof. Worked well with my MX5 some years ago

I did one recently, not as bad as yours. This worked well and also wasn't too time consuming:

Soak with water. Just a garden sprinkler, not a pressure washer. Then agitate with a drill mounted brush - this kind of thing: https://www.ebay.co.uk/itm/374835142425?_skw=drill...

Then rinse off with water.

I just kept going, maybe 4-5 times, before the rinsed water was completely clear. It took about 30-45 mins, and went thru about 3 battery charges (I have 2 batteries so was able to charge one while using the other) on a compact 12V cordless drill.

Failing that, a mini steam cleaner would probably do it:

Assuming you want it black, get some Cherry Blossom shoe polish and a good shoe brush and spend half an hour rubbing it in.

It will come up like new.

Cost? £2.00

Done this a couple of times, and it will help waterproofing as it's wax based.

I managed to shift this eventually with a combo of surfex hd, renovo cleaner and a scrubbing brush. Bloody hard work though!

Careful with the cleaning products used, and how you rinse down. The wrong stuff rots the stitching, as I found (six months later)

I’ve used fairy liquid and a dash of milton, bucket of hot water and a scrubbing brush.
Takes time and elbow grease but gets there in the end.
I think you need the milton to kill the green stuff.

As above the renovo cleaner is good. You'll need a nail brush and a couple of hours of scrubbing to get it right.
Vacuum the hood to remove any dust and loose debris
Apply the renovo neat or 50:50 mix with warm water in a bowl
Scrub the entire roof following the direction weave. Once you've covered the whole roof (30 mins of scrubbing at least) leave it for 20-30 mins.
Rinse off the solution and either let dry for a bit or use a wet vac to get the worst of the moisture out.
Keep repeating this process until the soltuion you are dipping the nail brush in no longer starts going green from the mildew stuff you're getting out the fabric.
Vac dry / leave to go bone dry in the sun
Apply a dedicated hood proofer or Fabsil Gold. Several coats gives the best protection
