Ob\u00e1vam sa, \u017ee v\u00e1s mus\u00edm hne\u010f sklama\u0165: Neexistuje jednoducho \u017eiadna chemick\u00e1 ani fyzik\u00e1lna met\u00f3da, ktor\u00e1 by dok\u00e1zala \u00faplne a magicky odstr\u00e1ni\u0165 siln\u00fa hrdzu len za 5 min\u00fat. Hrdza (oxid \u017eeleza) je v\u00fdsledkom chemickej reakcie, ktorej vznik trval ur\u010dit\u00fd \u010das \u2013 a jej zvr\u00e1tenie tie\u017e trv\u00e1 ur\u010dit\u00fd \u010das.<\/p>\n\n\n\n
Ak vid\u00edte online vide\u00e1, ktor\u00e9 s\u013eubuj\u00fa, \u017ee hrdzav\u00e9 n\u00e1stroje bud\u00fa po 5 min\u00fatach namo\u010denia do z\u00e1zra\u010dn\u00fdch zmes\u00ed op\u00e4\u0165 vyzera\u0165 ako nov\u00e9, zvy\u010dajne ide len o m\u00e1giu pri strihan\u00ed videa.<\/p>\n\n\n\n
Ale nebojte sa! Existuj\u00fa met\u00f3dy, ktor\u00e9 s\u00fa extr\u00e9mne r\u00fdchle (hoci m\u00f4\u017eu trva\u0165 15 a\u017e 30 min\u00fat alebo si vy\u017eadova\u0165 ur\u010dit\u00fa svalov\u00fa silu) a met\u00f3dy, ktor\u00e9 s\u00fa super \u00fa\u010dinn\u00e9 (ale trvaj\u00fa nieko\u013eko hod\u00edn).<\/p>\n\n\n\n
Tu s\u00fa najlep\u0161ie a najrealistickej\u0161ie sp\u00f4soby, ako \u010do najr\u00fdchlej\u0161ie zachr\u00e1ni\u0165 svoj predmet:<\/p>\n\n\n\n
Ak to naozaj treba urobi\u0165 hne\u010f, chemik\u00e1lie nepom\u00f4\u017eu; pom\u00f4\u017ee iba hrub\u00e1 sila. Toto funguje skvele na povrchov\u00fa hrdzu.<\/p>\n\n\n\n
\u010co budete potrebova\u0165: Dr\u00f4ten\u00fa kefu, oce\u013eov\u00fa vlnu (jemn\u00fa, napr. triedy 000) alebo jemn\u00fd br\u00fasny papier.<\/p>\n\n\n\n
Ako na to: Hrdzav\u00e9 miesta prebr\u00faste siln\u00fdm tlakom. Na ploch\u00e9 predmety m\u00f4\u017eete pou\u017ei\u0165 aj akumul\u00e1torov\u00fa v\u0155ta\u010dku s n\u00e1stavcom na dr\u00f4ten\u00fa kefu \u2013 t\u00fdmto sp\u00f4sobom m\u00f4\u017eete hrdzu odstr\u00e1ni\u0165 za menej ako 5 min\u00fat.<\/p>\n\n\n\n
Bonusov\u00fd tip: Po\u010das drhnutia naneste na postihnut\u00e9 miesto kvapku penetra\u010dn\u00e9ho oleja (ako WD-40) alebo dom\u00e1ceho oleja. T\u00fdm sa hrdza r\u00fdchlej\u0161ie uvo\u013en\u00ed a prach sa via\u017ee.<\/p>\n\n\n\n
\u010co budete potrebova\u0165: Pr\u00e1\u0161ok kyseliny citr\u00f3novej (z drog\u00e9rie\/supermarketu) a hor\u00facu vodu.<\/p>\n\n\n\n
Postupujte takto:
Rozpustite 2 \u2013 3 polievkov\u00e9 ly\u017eice kyseliny citr\u00f3novej v miske s hor\u00facou vodou (teplo v\u00fdrazne ur\u00fdch\u013euje reakciu!).<\/p>\n\n\n\n
Vlo\u017ete predmet do roztoku. Okam\u017eite uvid\u00edte, ako sa tvoria mal\u00e9 bublinky.<\/p>\n\n\n\n
Po 15 a\u017e 20 min\u00fatach vyberte predmet a jednoducho zotrite zm\u00e4knut\u00fa vrstvu hrdze starou zubnou kefkou.<\/p>\n\n\n\n
\u26a0\ufe0f Pozor: Kyselina citr\u00f3nov\u00e1 odstra\u0148uje v\u0161etko \u2013 vr\u00e1tane n\u00e1terov alebo zmodrania na n\u00e1strojoch. Nenech\u00e1vajte ch\u00falostiv\u00e9 predmety v roztoku pr\u00edli\u0161 dlho.<\/p>\n\n\n\n
Na men\u0161ie predmety alebo chr\u00f3mov\u00e9 \u010dasti (napr. riadidl\u00e1 bicykla).<\/p>\n\n\n\n
Postupujte takto: Nalejte na predmet be\u017en\u00fd dom\u00e1ci ocot. Vezmite kus hlin\u00edkovej f\u00f3lie, vo\u013ene ju pokr\u010dte, namo\u010dte do octu a vydrhnite n\u00edm hrdzu.<\/p>\n\n\n\n
Pre\u010do to funguje: Hlin\u00edkov\u00e1 f\u00f3lia je m\u00e4k\u0161ia ako oce\u013e (tak\u017ee kov takmer nepo\u0161kriabe), ale chemicky reaguje s kyselinou v octe a prekvapivo r\u00fdchlo rozp\u00fa\u0161\u0165a hrdzu.<\/p>\n\n\n\n
Ve\u013emi d\u00f4le\u017eit\u00e9 po o\u0161etren\u00ed:<\/p>\n\n\n\n
Ke\u010f hrdza zmizne, kov je \u00faplne nechr\u00e1nen\u00fd a v okamihu znova hrdzavie (povrchov\u00e1 hrdza v priebehu nieko\u013ek\u00fdch min\u00fat!).<\/p>\n\n\n\n
Po o\u0161etren\u00ed kyselinou predmet d\u00f4kladne opl\u00e1chnite \u010distou vodou.<\/p>\n\n\n\n
Ihne\u010f ho a d\u00f4kladne osu\u0161te (m\u00f4\u017eete pou\u017ei\u0165 aj f\u00e9n).<\/p>\n\n\n\n
Priamo ho votrite trochou oleja (napr. WD-40, olej do \u0161ijac\u00edch strojov alebo v n\u00fadzi repkov\u00fd olej), aby ste chr\u00e1nili kov pred kysl\u00edkom<\/p>\n","protected":false},"excerpt":{"rendered":"
