Frequently Asked Questions: 1953 Clean & Protect (Liquid Coil Cleaner with Protectant)

Application & Performance

Q: What is 1953 Clean & Protect designed to do?
A: 1953 is a non-foaming PM coil cleaner that lifts routine soil and helps leave a microscopic protective barrier designed to reduce dirt re-adhesion and routine re-soiling between service intervals. It’s built for repeat maintenance on evaporators and routine/light condenser cleaning.

Q: What dilution should I use?
A: Use dilution that supports the protectant finish:

• Evaporator Coils: Mix 3–4 parts water : 1 part 1953. Spray, allow a 4–6 minute dwell, then follow the label rinse pathway (self-rinse only when appropriate operating conditions exist; otherwise use a manual rinse/wipe approach as needed).
• Outdoor Condenser Coils (Routine/Light Soil): Mix 3–4 parts water : 1 part 1953. Spray, allow a 4–6 minute dwell, then rinse thoroughly with water.

Q: Why does dilution matter more for this product?
A: 1953 is designed to leave a protective micro-barrier behind. Staying in the 3:1–4:1 range helps ensure enough protectant remains after cleaning. Over-diluting can reduce the protective finish and shorten the time until routine re-soiling returns.

Q: Do I have to rinse it?
A: Outdoor condensers: YES—rinse thoroughly with water after dwell. Evaporators: follow label directions and job conditions. If your application depends on a “self-rinse” pathway, that requires the system to be in cooling mode and producing condensate.

*Tech Note: If the system is not producing condensate (low humidity, heating mode, fans only), use a manual rinse/wipe approach after dwell time per standard service practice and the product label.*

Q: Is 1953 a replacement for a heavy-duty deep-clean?
A: No. 1953 is a PM platform intended for routine soil removal and a protective finish between visits. For severely impacted coils (thick mats/heavy blockage), deep clean first, then finish with 1953 to leave the protective barrier that helps reduce dirt re-adhesion between PM cycles.

Q: Can I use it on outdoor condenser coils?
A: Yes—on routine/light soil. Use 3–4:1, allow a 4–6 minute dwell, then rinse thoroughly with water. It’s ideal when you want routine cleaning plus a protective finish between PM cycles.

Q: What type of sprayer should I use?
A: A standard pump-up sprayer or professional coil-cleaning sprayer works best. Use a fan tip that delivers even coverage and avoid atomizing into a mist indoors. After use, rinse the sprayer, wand, and nozzle thoroughly with clean water.

Q: What’s the correct mixing order?
A: Always add water first, then add concentrate to reach your dilution. This improves mixing and reduces splash-back risk. Use clean water and keep your dilution consistent for repeatable outcomes.

Q: Is foam required?
A: No. 1953 is a non-foaming cleaner designed to wet fin surfaces and lift routine soil while leaving a protective finish. Focus on even wetting, proper dwell, and the correct rinse pathway.

Q: How much ready-to-use solution does one gallon make?
A: It depends on your dilution:

• 3:1 (water:product): makes 4 gallons of ready-to-use solution per 1 gallon of concentrate.
• 4:1 (water:product): makes 5 gallons of ready-to-use solution per 1 gallon of concentrate.

Q: Do I need to neutralize it? Can I mix it with other chemicals?
A: Do not mix this product with other chemicals. Use it as directed at the recommended dilutions and rinse logic. Always follow the product label and SDS for safe handling and cleanup.

Q: How should I store it (truck, heat, freezing temps)?
A: Store sealed and upright. Avoid extreme heat and do not allow the product to freeze. If it has been exposed to freezing conditions or shows separation, follow your facility’s standard practice before use (and always follow the product label/SDS guidance).

Safety & Compatibility

Q: Is 1953 safe for microchannel coils or mini-splits?
A: Yes—when used as directed. Use the recommended dilution, do not over-dwell, and do not allow the product to dry on the coil. Microchannel/mini-split coils should be rinsed—do not rely on a self-rinse pathway for these coil types. Rinse outdoor coils thoroughly and follow label guidance for indoor applications.

Q: Can I let it dry on the coil?
A: No. Do not allow the product to dry on coil surfaces. Drying increases the risk of residue and inconsistent outcomes. Re-wet if needed during dwell, and complete the appropriate rinse pathway.

Q: Is it safe on coated coils?
A: Coil coatings vary by manufacturer. As a best practice, test a small inconspicuous area first and follow the equipment manufacturer’s cleaning recommendations for coated coils.

Q: Do I need PPE?
A: Yes. Always follow the product label and SDS. Wear appropriate PPE such as chemical-resistant gloves and eye protection and use standard chemical handling procedures on the job-site.

Q: What about electrical components and surrounding surfaces?
A: Avoid direct spraying into motors, control boards, sensors, and exposed electrical components. Use standard service practices: protect sensitive areas, control overspray, and wipe or rinse overspray on surrounding surfaces to prevent residue and maintain a professional finish.

Logistics & Value

Q: Why choose 1953 instead of a standard coil cleaner?
A: 1953 is built for repeat preventive maintenance. You get routine soil removal plus a protective micro-barrier designed to help reduce dirt re-adhesion between visits—ideal for service intervals where “clean today, stay cleaner longer” matters.

Q: What is the shelf life?
A: Vapco products carry a 1 year manufacturer warranty. When stored sealed and properly, 1953 has a shelf life of 3+ years.

Q: How do I dispose of the empty container?
A: Follow local regulations. Rinse the container per your facility’s standard practices and recycle or dispose of it according to municipal and job-site guidelines.
