Do any pressure washers have anything other than just one rate of

Don't know. But can't you adjust the dilution manually by diluting the
cleaning liquid?

Many models have adjustable chemical injectors and there are add on
adjustable chemical injectors. Look at the northerntool site, they have
a wide array of pressure washers and components.
