I don't understand why you'd quote that way. Though unlikely, you could potentially match a filename in the working directory, and hose the sed command. For efficiency's sake, you can eliminate cat and one of the two sed processes, and still have a more readable command:
sed -e 's?foo?bar?g' \ -e 's?dirty?clean?' \ < file.txt > file2.txt
