Tim keluarga kemudian mencampur bakteri dengan gel berbasis alga alami dan menyebarkannya pada lukisan - yang diambil dari dinding pada tahun 1960-an, kemudian dipaku kembali, masih tertutup lem. Setelah tiga jam, gel dihilangkan, memperlihatkan lukisan yang bebas lem.

Bosch juga telah menerapkan penggunaan bakterinya pada proyek restorasi di Pisa dan Monte Cassino di Italia dan di Santiago de Compostela di Spanyol utara. Dia sekarang melatih kelompok bakteri jenis lain untuk membersihkan dinding dari grafiti yang dicat semprot.
