- Credit card (or loyalty card etc)
- Penny (US or UK, or a 2p works better)
- Rough sponge
- Convertable roof Shampoo & Waterpoofing
- chamois leather or similar non-linting cloth like a microfibre cloth.
I used a branded kit which had a rough sponge included, but you just need a fairly stiff sponge - not your usual car cleaning sponge!
Step 1: Preparing
Dried on big thick stains like bird poop, you won't be able to get it off with a shampoo unless you remove the bulk before starting to soak.
Several options are available but a penny can be good to remove dried on bits. I can also recommend your own fingernail as long as you've not got any cuts and remember to clean your hands well (including under the fingernails!). Make sure you do this outside not in a garage so that you don't breath in the dust - its not nice.
Use a hoover to remove the dust and other rubbish off the roof.
Step 2: Wet and Shampoo
In this photo, I realise it looks black already, but it's because I was too stupid to show you it being used on a stain.
After you've sprayed on some shampoo, first use circular motions to work the shampoo in, leave for 5-10 minutes to lift the stain and then follow the grain of the fabric.
Step 3: Rinse - But It's Not Over...
Step 4: Drying & Waterproofing
Spray on the formula ensuring that you get good coverage. It's a good idea to wait until the roof is entirely dry as it's easier to see what bits you've covered. Otherwise do it methodically so you don't miss any bits.
You're done - though you'll need to wait 12-24hrs before getting it wet again!
