500ml Viper Evap+ Coil Cleaning solution

The part of the kit that actually does the work

The brush, the catch bag and the cover get you inside the unit. This is what happens once you're in. Viper Evap+ is the coil cleaning solution that ships in every Home DIY Kits aircon kit, and it's the part that clears the built-up grime and biofilm off the evaporator coils, not the tools around it.

If you already own a kit and you're onto your second or third unit this season, or your second or third year of ownership, this is the refill. You do not need to buy the brush and catch bag again, just the solution that does the actual cleaning.

What it clears

Evaporator coils build up a layer of dust, oil and biofilm that a plain water rinse never shifts. That layer is what causes the musty, dirty sock smell when the unit kicks on after sitting idle. Viper Evap+ is a non-rinsing formula that breaks that layer down so it clears away properly, instead of just getting pushed around inside the unit.

Who this refill is for

• Anyone who already owns a Home DIY Kits cleaning kit and has run out of solution
• DIY Dads doing more than one unit who want the professional-grade chemical without paying for the tools a second time
• Anyone running a regular maintenance clean on a split system or ducted unit

How far it goes

500ml is enough to do several units, so it suits a household with more than one system, or someone helping a neighbour or family member get theirs done at the same time. It works the same way on split system and ducted evaporator coils. Spray it onto the coils, let it work, wipe down. No rinsing gear needed.
