need correct chemical for tinted windows

What is the correct chemical to use for tinted windows please -

the homeowner says I should not use anything with ammonia in it -

does anyone have a recommendation?

Thanks -

If its old tint,check to make sure its not peeling,by just useing a sponge&a squeege.It its new tint any soap is fine as long as you wipe the edges so as not to let it get underneath the edge and delaminate the film.useing a microfiber towel is the fastest way to get the edges.avoid ammonia anyway because it stinks.

so - I use a liquid soap and water solution with a micro fiber towel -

thanks
