Ashley Stephens, 20, John Averis, 27, Darren Yates-Badley, 24, and Ian Reid, 44, died tackling a warehouse blaze in Atherstone-on-Stour on 2 November.
Saturday's initiative involved cars being washed in return for a donation.
Surrey Fire and Rescue spokesman Peter Guest said it was a way of showing solidarity with the victims' families.
"The loss of colleagues in Warwickshire will have struck a chord with firefighters all over the country.
It's important for us to show our support by taking part in this charity
"What makes the fire and rescue service a unique service to be part of is that at times like this, everyone rallies together to support each other."
Other fundraising events across Surrey, such as a fire engine pull, were also held.
Firefighter Robin Williams, from Walton fire station, said the aim was to raise as much money as possible.
"You only have to ask yourself, how would we feel if we lost a member of our crew and what would be the impact on their family?
"It's a horrible thought so it's important for us to show our support by taking part in this charity day."
