Mubuzyo: Tulijisi sikwashi wakuwida mbuli chintu chakulisakatizya aatebulu lyesu lyakulida lya maple, lyamanizya biyo amafuta aa linseed, ngotubelesya chiindi choonse. Itanga lyakazuza mpawo lyakasiya kabala. Sena kuli nzila yakucigwisya?
K. Kuli nzila zyiingi zyakugwisya mabala aasiya kuzwa kuchisamu, asi weelede kusola nzila zyiingi.
Kanjikanji, mabala aasiyidwe aachisamu alachitika akaambo kakusangana kwamuwo ama tannins, alo aajana zina lyawo kuzwa kuzintu zijanika muchikumba cha oak amusamu wa oak mpawo zyakabelesegwa kusanzya chikumba kwamyaka myiingi. Ma tannins alimwi alajanika mumicelo myiingi, muzisyumani, amuzisyango zimwi. Nchintu chikwabilila mubili kuzwa kuzintu zikonzya kunyonganya mubili mpawo ziiyo zyiingi zili mukulanga buumi bwakulya chakulya chilaa tannin.
Ma tannins alanyonyooka mumaanzi. Mbuli nkuni mbozitontola mpawo maanzi mbwaazwa, zileta ma tannins atala aawo ma tannins manji nkwaasyeede. Eezi zilachitika chiindi chiingi kuzisamu zijisi tannin zilimbuli oak, walnut, cherry, antoomwe a mahogany. Maple ajisi ma tannins masyoonto, pesi ma tannins aali mumusinza wamapumpu alakonzya kuti akaswaangana ama tannins aali mu maple kuchita kuti kube bbivwe.
Mabala asiya aachisamu alakonzya kuchitwa abuumba, oobo bupangwa aawo chisamu nobuteteete mpawo buli chakulya chama fungi aasiyene-siyene aazyibidwe kulindiswe kuti nkumba naa nkumba. Mbuli zintu zyoonse zitakwe busani, musamu wamapunga ulakonzya kubelesegwa mbuli chakulya.
Oxalic acid ilagwisya mabala aa tannin mpawo chlorine bleach ilagwisya mabala aa nkumba. Oxalic acid nchintu chijanika mu Bar Keepers Friend Cleaner ($2.99 ​​  ku Ace Hardware), pesi chipanga munsi a 10 pesenti yazintu zili muchikombelo, kweendelanya apepa lyakukwabilila lyasikupanga. Oxalic acid alimwi ilajanika mu Bar Keepers Friend musamu wakusanzya uuteteete, pesi mubunji busyoonto. Kuti ujane bube butakwe busani, langa zintu zilimbuli Savogran Wood Bleach ($12.99 ku 12-ounce tub ya Ace) mumulyango wakupenta.
Nokuba boobo, oxalic acid a bleach zyeelede kuswaangana aamasamu aamusamu kuti zibeleke. Aboobo, basikubamba zintu zyamuŋanda basaanguna kugwisya zintu eezyo kwiinda mukubelesya misamu iikola naa kusanzya. Nokuba boobo, nchaantangalala kuti kabala kakanjila kumamanino, aboobo ulakonzya kufwambaana kuzuza kuya kumutwe wa oxalic acid munsi kuti ubone naa oxalic acid yakanjila loko kuchitila kuti kabala kasyoonto kakugwisigwa. Lugwalo ndondakajana lwakatondezya zifwoto zya ntaamu a ntaamu zya kabala kasiya kali kugwisigwa kuzwa kuchisamu kakunyina kugwisigwa a paste ya zibeela zyobile zya Bar Keepers Friend cleaner a 1 cibeela camaanzi kwamaminiti masyoonto, mpawo chisela cha cleaner acisela cha maanzi. Mulembi walugwalo oolu wakabelesya 0000 yaboya bwabutale bubotu bwakubelesya kwabili, asi inga cainda kubota kubelesya bulo bwakupanga. Boya bwabutale buyoosiya zibeela-beela mumapopwe aacisamu, mpawo ma tannins ayooswaangana abutale, akusandula cisamu chili afwaafwi kuti chibe chisiya.
Kuti ulakonzya kweendelezya tombe mpawo koliboteledwe azyazwa, nkubotu! Nokuba boobo, zilalangilwa kuti tokonzyi kujana mubala uukozyenye. Nchicho chakapa kuti basyaazibwene basungwaazye kusaanguna kugwisya chikumba, kusilika tombe, mpawo kuchibamba lubo.
Kuteteeta ninzila mbotu yakugwisya zintu zyakale nkaambo bbala lyazintu zyakale lilayandika. Carol Fiedler Kawaguchi, ooyo uubambulula zintu zyakale azintu zimwi zyamuŋanda kwiinda mukkampani yakwe yaku Bainbridge Island, Washington-based C-Saw, ulalumbaizya kubelesya musamu wa bukoko butakwe busani abwaanda bwa lacquer. Kuti ulikwabilile kuzwa kubusi, kobeleka anze kuti kacikonzeka naakuti kusama chisoti chilamfu chili achisefa chabusi. Amusame magilovu amagilazi aatakonzyi kujatikizyigwa amakemikalu. Aaya ma solvents alafwambaana kumana, aboobo kobeleka mumasena masyoonto kuti ugwisye naa kukwasula cibeela cijisi busani kacitanayuma.
Naa, Kawaguchi waamba, ulakonzya kubelesya Citristrip Safer Paint a Varnish Striping Gel ($15.98 lita lyomwe ku Home Depot). Eechi chintu chakusanzya tachinunkili pe, chikkala kachili chitete mpawo chibeleka kwamahola miingi, mpawo chililembedwe kuti chili kabotu kubelesegwa mukati. Nokuba boobo, mbuli mbomukonzya kubona kuzwa mumabala masyoonto aalembedwe, amubone kuti muya ulanjila kabotu alimwi amusame magilovu amagilazi aatakonzyi kunjila mumakemikalu.
Kuti koyanda kutantamuka kugwisigwa kwamakemikalu, kusanzya ninzila aimbi – eezi zilakonzya kukkomanisya kapati kumapulojekiti aatabelesyi zintu zyakaindi alimwi ajisi busena bupapalete kakunyina kubamba zintu zikatazya zikonzya kupa kuti kusanzya kukatazye. Belesya chibelesyo chakusanzya cha 5′′ DeWalt Corded Hook & Loop Sander ($69.99 ku Ace). Ule bbokesi lyamapepa aakusanzya aakati-kati ($11.99 kumavwili aakusanzya aa Diablo ali kkumi amusanu) antoomwe amapepa masyoonto aamapepa aakusanzya (220 grit). Kuti kacikonzyeka, gwisya tebulu anze naakuti mugaraji kuchitila kuti zibeela zya nkuni zitanjili koonse koonse. sanguna apepa lyakusanzya lyakati-kati. Mafuta aamusamu wa linseed alasangana a oxygen iili mumuwo kuti apange pulasitiki. Ooku kuchincha kulafwambaana kumatalikilo, mpawo kwacheya mpawo kwatola myaaka myiingi. Kweelana akuti kumanizya nkuyumu biyeni, ulakonzya kuchisanzya ansi. Naa, kadonsi kaniini ka mafuta kalakonzya kupanga apepa lyakusanzya, eecho chikonzya kuchesya kubeleka kwacho. Langa pepa lyakusanzya chiindi choonse mpawo ulichinche mbuli mbokuyandika.
Kuti wasyaala nkuni zitakwe chintu, ulakonzya kugwisya tombe. Amusole oxalic acid kusaanguna. Ilebuli lya Savogran lyaamba kuti swanizya chibiya choonse cha 12 ounce a galoni lyomwe lyamaanzi apya, pesi ulakonzya kugwisya mpawo usanganye kota yazintu zili mukati a lita lyomwe lyamaanzi apya. Belesya bbulasho kumwaya musamu woonse atala aatebulu, kutali buyo aawo mpaali. Linda kusikila inkuni yasalala mbuli mboyanda. Mpawo pukuta ziindi zyiingi achisani chisalala, chitete kuchitila kuti asanzye. Syaazibwene mukubamba zintu zyaatala Jeff Jewitt waamba mubbuku lyakwe lya Making Furnishing Refinishing Easy kuti kugwisya mabala kulakonzya kuyandika nzila zyiingi zyakusilikwa antoomwe amawoola manji aakuyuma aakati.
Kuti oxalic acid tiikonzyi kugwisya tombe, ssola kusanzya chlorine bleach ku tombe mpawo uleke masiku woonse. Kuti mubala wazima mbichaani, pesi katazulide pe, kozumanana kuchita oobo ziindi zyiingi, pesi ambweni buzuba boonse kuchitila kuti ukonzye kulanga-langa akumanizya kusilikwa kakutanaba kuchincha mubala. Kumamanino, gwisya akusanzya a 1 cibeela cha vinegar iituba antoomwe a 2 zibeela zya maanzi.
Kuti kabala katamani, ulakonzya kusala nzila zyotatwe: kwiita sikupenta uuchibwene; kuli ma bleach aanguzu, pesi taaliwo chiindi choonse. Ulakonzya kuchisanzya ansi mane doti lyamana, naakuti libe litete loko kuti litakunyonganyi pe. Naa kubamba nzila yakubelesya cibeela chaakati mbuli chintu chakubikkila kutebulu.
Kuti wabelesya oxalic acid naa bleach, nikwakamana nkuni kuyuma, kusanzya kwamamanino akusanzya kwabulongo buteteete kuyooyandika kuchitila kuti kugwisigwe nsinga zyakatanta atala akaambo kakujatana amaanzi. Kuti kotayandi chintu chakusanzya mpawo kotakwe, ulakonzya kuchita amaanza apepa lyakusanzya lya 220 grit. Gwisya bulongo boonse bwakusanzya, mpawo ulakonzya kubikka mafuta aamusamu wa linseed naakuti kufumbwa nchoyanda.
