HotShot RDX is the only proven, effective, windshield washer fluid heating system that offers consumers both safety and convenience at an affordable price. Patented, proprietary technology enables its heating system to heat windshield washer fluid using a minimal amount of energy produced by the vehicle’s electrical system to remove frost, ice, snow, bugs, glare and other debris. The heated wash has been proven to be safe and effective in tests on all types of windshield glass and in many environments.

Hot water cleans better than cold! HotShot RDX dramatically improves the performance of the factory washer system by providing heated fluid every time the washer system is used. Works better than de-icing fluid, ice scrapers and even bug wash. 

HotShot Cutaway View   How it Connects

The Heated Wash AT-38OD operates in “On-Demand” mode

The unit starts to operate when the ignition is on (engine running) and battery voltage level is higher than 13.0 volts.  Once the unit is activated, the washer fluid inside its heating chamber will be heated and kept within pre-determined temperature limits (125 – 135°F), so there is always hot fluid inside the unit’s heating chamber which can be used by a driver for cleaning the windshield.  

Each time the driver activates the factory installed washer system, heated washer fluid is applied to the windshield for approximately the first 3 seconds of spray. Three seconds of the spray delivers approx. 50-60 cc of fluid that is considered sufficient amount of fluid for one spray. The next portion of heated washer fluid is available in 10-20 second(depending on ambient conditions).

The HeatedWash unit uses full power of 50 Amps for 30 seconds to heat the washer fluid up to pre-determined temperature limits (125 – 135°F), and minimal power to keep it within these limits. The unit’s power consumption is less than 2 Amps per hour.  

Once the unit starts to operate (engine is running), it will heat the washer fluid in approximately 30 seconds; driver operates the washer system manually to spray the heated washer fluid onto the windshield. Recommended duration of spray is 3 seconds. Driver can spray as many times as he wants. Best results are achieved  when time intervals between sprays are approx. 20 seconds.
