Cheese sauce separates due to high heat or improper emulsification. Maintain a low temperature while cooking and stir constantly. To prevent separation, start with a roux (butter and flour mixture) and slowly add milk or cream before incorporating the cheese. Use high-moisture cheese and avoid pre-shredded varieties, which contain additives that hinder smooth melting.
