Lever Brothers' newest launch, Persil Revive, brought big brand strength to home dry cleaning ­ a category so far occupied by ACDOCO's Glo White in the UK and P&G's Dryel in Ireland. It is too early for sales figures yet, but Lever estimates Revive ­ which is used in the tumble dryer ­ will bring £30m a year in incremental sales to the category. {{MARKETING }}
