Household cleaning specialist Spontex is running a two-month on-pack promotion using a text mechanic across five of its brands.
Participants need to look for a code under a Spontext to Win' sticker on special packs of Window Wonder, Brilliant and Tough Scourers, Washups and Second Skin household gloves.
They text the code to the phone number given and receive a symbol in reply if they have won.
The weather-related symbols build on the brand's previous sponsorship of GMTV's Weather slots. A sun symbol means the consumer has won one of four family holidays worth £4,000, a raincloud denotes that the prize is a £2,000 new bathroom suite, while a stormcloud indicates a flat screen TV set.
