Underbody cleaning

[Jonny TVR]

I have a concours classic car but intend on using regularly. The underside is immaculate. Just wondering how I keep this looking good. Obviously regular pressure washing under the wheel arches but how do I get under the car easily. Have seen a karsher attachment that looks good. Any suggestions?

Will spraying detergent underneath wash all grease etc away that is looking after stuff. So it will always be "raw" to oxidising?

Thats a good point but the car is stored in a carcoon which will reduce moisture. just wondering whether a wax should be applied to the underside.

May even was the underside for winter.

Not if you use it regularly........get the car under-sealed with Dynax clear wax.

Thats a really good point. Going to get some advise on clear underbody rust protection. The chassis has been injected but no other treatment elsewhere. I won't be using either in wet weather, they will be stored in carcoons and will do around 2.5k miles a year each.

Used the Karcher underbody yesterday and what a great product. Very effective.

The problem with even the clear treatments underbody is that they will attract dirt/ dust. I'm going to leave it untreated and just keep it clean and dry. Storing in a carcoon as well so should be ok
