Can anyone please suggest a way to remove the white streaks from the side of the MoHo, they're more prominent on the matt black and silver decals on the side.

I washed it last evening after the sun had gone down and it was a little cooler outside. Chamois leathered off with some fresh water this morning and loads of streaks all down the side (see attached images A & B).

Tried washing again but to no avail. Its a bit hot to try and polish them out just now. although I'm not sure polishing will do the trick.

Any suggestions or advice will be greatly received.

Thanks- Derry

I'm guessing you live in an area with limescale problems?

The white lines are mineral deposits which are carried in the water you use to wash your van. When the water evaporates it leaves the minerals behind which dry out out on the bodywork. The white marks are mineral deposits.

EXAMPLE - Imagine washing your van with a bucket of water and you added a bag of salt to it. The salt will dissolve in the water. It wont be visible. The water will appear clear. When the water evaporates, the salt will appear on the surface. This is what you can see - mineral (salt) deposits.

These are the same mineral deposits that form limescale in your kettle.

If you live in an area with high mineral deposits you can use De-Ionised (DI) water to rinse your van. This is an ultra clean, purified form of water with almost zero deposits parts per million.

It's easy to make DI water. It can be made as and when you need it.

You don't need to wash your van or jet wash it with DI water, just rinse it down with DI water.

It's the same stuff window cleaners use with those big long poles.

Here's a few links -

You can buy DI vessels with resin from eBay. Here's just one link. There are hundreds!


It just plugs into your outside tap like a hospepipe and you rinse your van.

I have used Autoglym active insect remover on Decals before without issue but do wash it off, I spray a little on wipe over with a microfibre cloth rinse and then wipe dry with a microfibre cloth. If using on paintwork I use the Autoglym Aqua wax after.
