Default Re: Polishing a Vintage Caravan

The trouble with polishes like Silvo and Brasso is they contain ammonia. From all the reading I have done on polishing aluminium it is not wise to use polishes with ammonia which can cause tarnishing of the aluminium in a short period of time.
A line taken from a US polishing forum "polishes contain ammonia which can cause aluminum to oxidize and tarnish a lot faster than it should. Products with ammonia seem to work really good but they do more damage in the long run. Be careful what you use!"
