What is a 'mild detergent' ?

[fazer6868]

Reason i ask is if you use acf 50 you should only use mild detergent to wash the bike so as not to remove the acf.

Trouble is not being too genned up on detregents i haven't got the faintest idea what is a mild detergent and what is a strong one!

I normally use muc off to clean the bike.

Thanks
