Reberi iboneye kandi izwi kandi nkabakozi bashishikaje. Ibintu bidasanzwe cyangwa kama gakoreshwa mugukora ibintu bihurira neza. Irashobora kugwiza ubushobozi bwihuse, kugabanya umubare wihuta, no kugabanya igihe cya gilcanisation. Byinshi mubikoporora inoristanic ni okide yicyuma, hydroxide hamwe na karubone yibanze, nka cardoxide ya kamere, ikurikirwa na aside irihuta, nibindi nka acide, zinc nibindi. Dosage rusange iri munsi ya 5% yuburemere bwa reberi.
