If you want to do it right, then remove the tank and do it all over again -right the first time. You and we don't know what was originally used, one popular product is called POR-15 but I never heard any negative things about it. EASTWOOD products sells it and others as well. You are not going to get it cleaned out by leaving mounted on the tractor. Bite the bullet. If you do recall what product you used, I'd contact the manufacturer and scream bloody murder.
