Diamond Bright - alternatives

regular washing with a good vehicle wash and wax will keep it looking good.

Have a look at www.tourershine.co.uk they have some good reccomendations and they are mobile.

If it's anything like car dealers, the only reason they push it, is because they get a healthy commission on the sale. I've had three cars done with a similar product in the past (supposedly included in the deal - I wouldn't pay for it outright) and its only lasted a few months.

I polish our van two or three times a year with Autoglym and only ever wash it with Stardrops (it doesn't have salt in it and therefore doesn't remove the polish like some detergents).  The van is gleaming and any streaking (which doesn't happen much) easily washes off again.

If you're having to pay for it - personally I wouldn't bother.  You can buy a lot of Autoglym for the same amount.

Fenwicks have a product called Bobby Dazzler Shield. I've seen it applied to a car (in exactly the same way as Diamond Bright) and the results were amazing.

It costs a fraction of the price and if you can do the van yourself, it will save you a small fortune. 

I find the interior treatment well worth it. Any accidental spillage is quickly cleaned with  damp clothe work really well
