Product Overview

I recently had the opportunity to review the Leak Saver Foam Blaster 18oz. Penetrating Coil Cleaner. This product is a professional grade formula designed to supercharge your coil cleaning and restore efficiency. I found it to be quite effective when used on dirty coils, as well as other HVAC units, refrigeration systems, automotive radiators, fan blades, metal filters, and more!

The Foam Blaster works by using a high pressure spray that penetrates deep into the coil and then actively expands into a dirt liquifying foam. It does an excellent job of removing dirt, grime, and odors from the coils and restoring their efficiency. Additionally, the delayed foaming action of this product ensures maximum coverage and contact time with the coils for a thorough clean. It can be used on both evaporators no rinsing required and condensers light rinsing with water required . When using on evaporators, the condensate water from the unit in operation will rinse off the dirt and product.

In terms of ease of use, I found this product to be surprisingly easy to install and operate. The instructions were straightforward and easy to follow. Additionally, it has a pleasant citrus scent which is not overwhelming or unpleasant. In terms of value for money, I believe this product is fairly priced given its quality and effectiveness.

Overall, I found this product to be quite effective in cleaning dirty coils and restoring their efficiency. It is suitable for use on all HVAC units, refrigeration systems, automotive radiators, fan blades, metal filters, and more! It is also easy to install and operate with straightforward instructions given in the package. Moreover, it has a pleasant citrus scent which makes it even more enjoyable to use. Therefore, I would highly recommend this product for anyone looking for an effective way to clean their coils!
