July 8 (Reuters) - Household lubricants and cleaning products maker WD-40 Co (WDFC.O) posted a better-than-expected third-quarter profit helped by improved gross margins.

Net income at the San Diego-based company fell 15 percent to $6.9 million, or 41 cents a share, from $8.1 million, or 49 cents a share, a year earlier.

Analysts on average were expecting earnings of 38 cents per share, before special items, according to Reuters Estimates.

Sales fell 16 percent to $68.8 million, short of analysts' expectations of $70.0 million.

Gross margin rose to 50.9 percent in the third quarter from 46.5 percent last year, helped by price increases over the past year, benefits from changes to the company's supply chain and declining oil prices.

For fiscal 2009, the company expects to earn $1.45 to $1.55 a share, including a foreign-currency exchange loss of 25 cents a share. Analysts were expecting earnings of $1.48 a share, before special items, for the period.

Shares of the company, whose brands include the Lava hand cleaner and Spot Shot carpet stain remover, closed at $28.08 Wednesday on Nasdaq. (Reporting by Abhishek Takle in Bangalore; Editing by Vinu Pilakkott)
