The music event's founder will install washing machines at the Worthy Farm site so muddy campers will be able to freshen up their appearance during 2013's run.
Glastonbury's operations director Melvin Benn is quoted by The Sun as saying: "Older fans are getting far more demanding and we have to respond. That means better toilets and now washing machine facilities."
The popular festival will take a scheduled break in 2012 to let Worthy Farm recover from the last few years.
Earlier this year, Glastonbury-goers were greeted by mud swamps at the site as rain hit the festival during its first couple of days.
However, the weather didn't stop Glastonbury from being crowned the 'Best Major Festival' at the UK Festival Awards 2011 earlier this week.
