Disable cheque payments but invoices still have it in

I've disable the cheque payment method but my invoices still have the "cheques payable to" text in them.

I tried to add some CSS to hide this but it does not work:

.cb-method cheque {

display:none;

}

I do not wish to accept payment by cheque anymore, only one company usually sends me a cheque per year but they will be stopping soon, it takes me an 30 minutes just to process a cheque with santander so it's not worth it for me.

I need to disable cheque payments completely please.
