On-Premise Laundry: Detergent, Pre-Spotter, and Sour
On-premise laundry fails in purchasing when one jug is asked to do the whole formula. Detergent, a pre-spotter or laundry degreaser, and sour sit in different parts of the wheel. If you run a hotel, a healthcare laundry, or a shop that washes oily wipes, the quote should name the step you are refilling.
Detergent is the wash bath. ICD stocks it as powder and as liquid in the laundry category. Red is a powdered detergent. TLC and 2X Liquid Laundry Detergent are liquids. Powder versus liquid is a dosing question: what the machine is set up to feed, and what the current formula already uses. It is not a quality ranking. Compare the sheets for soil type and for whether that specific detergent is written to run with or without a separate sour.
A pre-spotter or laundry degreaser is for stains and oily soil, before the wash or alongside it. Bandit is a liquid laundry degreaser. Allure is a pre-spotter. These do not replace the wash detergent. They also do not tell you, from this page, which stain they are for. Paint, ink, food, and shop oil are different soils. Read the product sheet for the soil it lists, and do not expect one spotter to cover the whole classification list.
Sour is the final rinse when the formula calls for it. Its job is residual alkalinity left from the wash, not sanitizing the linen. Buck is a laundry sour. Mist is a sour that also includes starch, so it is a finish product as well as a sour. This page does not set a finish pH and does not claim a sanitizing result. If your formula has a separate sanitizer step, that is a labeled product of its own, and it is not what sour means here.
One detergent sheet may say that formula does not use a separate sour. Follow that sheet for that detergent. Do not take that line and drop sour out of a different formula that still specifies it. The safe purchasing habit is to match the reorder to the formula you already run, then change the formula only when someone who owns the wash process rewrites it.
