Shake the bottle.
Switch off the device. Spray the contaminated area from a distance of about 10 cm (4 inch).
The active agent can be led by the attached extension pipe to the hard-to-access places as well. The special valve makes it possible that the bottle can be emptied in any of its positions.
Only use for switched-off devices. Do not spray it on hot or warm surfaces. If the material is sprayed into a closed device, aerate it for 20 minutes before switching on.
If the product may contact with plastic surfaces, perform a compatibility test in advance.
