Mazhinji emabhokisi ekugadzira anoshandisa guruu recornstarch rakagadzirwa kumba kana kuti rakatengwa. Guruu recornstarch remhando yepamusoro haringori nesimba rakanaka rekubatanidza chete, asiwo rinogona kuwedzera kumanikidzwa kwebearing uye kuomarara kwekadhibhodhi, uye muviri webhokisi hausi nyore kuchinjika.

Kana mhando yestarch yakasanganiswa negelatin isingasvike padanho iri, chiyero chemvura chinogona kuderedzwa zvakakodzera zvichienderana nemamiriro ezvinhu. Sezvo tembiricha ichikwira, chiyero chemvura chinofanira kuderedzwa zvinoenderana, borax necaustic soda zvinofanira kuwedzerwa sezvakakodzera, uye huwandu hwehydrogen peroxide hunofanira kuderedzwa. Guruu rakabikwa harifanirwe kuchengetwa kwenguva yakareba, kunyanya muzhizha, zvakanaka kurishandisa paunenge uchirigadzira. Kuwedzera 3%-4% formaldehyde, 0.1% glycerin uye 0.1% boric acid kune guruu kunogona kuwedzera kudzivirira mvura kwepepa, kukurumidzisa kumhanya kwekubatanidza, uye kusimbisa kuoma kwekadhibhodhi.bhokisi rechokoreti rechipo
Pamusoro pezvo, guruu remakemikari risingakuvadzi zvakatipoteredza, kureva guruu rePVA, rinogona kushandiswawo pakunamira bhodhi repepa.
