廚房油(you)(you)煙(yan)清洗(xi)(xi)(xi)的頻率取決于使(shi)(shi)用(yong)(yong)廚房的頻率和烹(peng)飪方式(shi)。一(yi)般來說，廚房油(you)(you)煙(yan)清洗(xi)(xi)(xi)建議每(mei)3至6個(ge)月進(jin)行一(yi)次。烹(peng)飪過程中產(chan)(chan)生(sheng)的油(you)(you)煙(yan)會(hui)附著在廚房的各(ge)種(zhong)表面上，如(ru)抽油(you)(you)煙(yan)機、煙(yan)道(dao)、瓷(ci)磚、墻(qiang)壁等(deng)。如(ru)果不及時清洗(xi)(xi)(xi)，這些油(you)(you)煙(yan)會(hui)積累(lei)在廚房內(nei)部(bu)，形成油(you)(you)垢，不僅(jin)影(ying)響廚房的外觀，還容易滋生(sheng)細菌和異味(wei)。油(you)(you)煙(yan)清洗(xi)(xi)(xi)的頻率應根據(ju)個(ge)人使(shi)(shi)用(yong)(yong)習慣和烹(peng)飪頻率來決定。如(ru)果經常使(shi)(shi)用(yong)(yong)廚房進(jin)行高(gao)溫烹(peng)飪，如(ru)煎(jian)、炸(zha)、烤等(deng)，油(you)(you)煙(yan)產(chan)(chan)生(sheng)的較多(duo)，建議每(mei)3個(ge)月進(jin)行一(yi)次清洗(xi)(xi)(xi)。而如(ru)果使(shi)(shi)用(yong)(yong)較少或者進(jin)行低溫烹(peng)飪，如(ru)蒸、煮(zhu)、燉等(deng)，食(shi)堂排煙(yan)罩清洗(xi)(xi)(xi)收費，可(ke)以每(mei)6個(ge)月進(jin)行一(yi)次清洗(xi)(xi)(xi)。
