From a long-running ad campaign:
Eliminate odors you’ve gone noseblind to for over 30 days with Febreze.
The intended parsing is High Attachment (HA) — eliminate for 30 days (with Febreze) odors you’ve gone noseblind to — though Low Attachment (LA) — odors you’ve gone noseblind to for 30 days, eliminate them with Febreze — is the default parsing. In a sense, LA is always available and often tempting, but in this case plausibility wins out over the default: why would you seek a remedy only for odors you’ve been noseblind to for over 30 days?
