Fog Machine with EVAP leak test

(sorry, I'm not good at English)



Hi guys,



my 2004 rx-8 shows CEL(p0455) EVAP system leak.



I want to find leak location using "Fog Machine" (it uses music concert)



but, I'm not sure it is safe to EVAP system.



I know the "Fog Machine Fluid" is water based.



I wonder it cause trouble like rust or other problem.



Anyone uses Fog Machine for Car's EVAP inspection???
