Car wash disclaimer notice

[will89]

I am doing a hand car wash for charity on the 13th november at my petrol station. I need to word a disclaimer notice to ensure that we are not held liable for any damage that is caused by using it. We are only using a hose so no pressure washer and car wash shampoo and some wash mitts.

Can someone on here advise of what i need to include in the disclaimed and how it should be worded?

Thanks in advance

Will.

Arent disclaimers usually not worth the paper they're written on?

I know a few guys on the landrover forum i use were talking about disclaimers for helping folk out during the winter/snow etc incase there was any damage caused by the recovery, and the basic jist of it was even if theres a signed disclaimer, if you make a mess of a recovery and damage the persons car then the disclaimer is in effect worthless.
