She really helped him clean up.

A Massachusetts house cleaner deserves a massive tip after turning up a long-lost winning lottery scratch-off — worth a staggering $1 million.

Khalil Soussa of Medford had purchased the Money Maker scratch-off at a local convenience store before forgetting to check if it was a winner and losing it.

Soussa told lottery officials earlier this month that his maid found the ticket in a vase months later and presented it to him — with him finding out it was a $1 million winner.

He said he would use the money to help out a friend and donate to charity, according to a press release.

The odds of winning the seven-figure second-place prize on the $30 scratch-off are 1 in 2,268,000, according to the state lottery.

Soussa could not immediately be reached for comment.
