 Therearethreebasicthingswhichcanbreakdownyourstainlesssteel’spassivitylayerandallow 
corrosiontorearitsuglyhead.
1)Scratchesfromwirebrushes,scrapers,andsteelpadsarejustafewexamplesofitemsthatcanbe 
abrasivetostainlesssteel’ssurface.
2)Depositsleftonyourstainlesssteelcanleavespots.Youmayhavehardorsoftwaterdependingon 
whatpartofthecountryyoulivein.Hardwatercanleavespots.Hardwaterthatisheatedcan  
leavedepositsiflefttosittoolong.Thesedepositscancausethepassivelayertobreakdownand 
rustyourstainlesssteel.Alldepositsleftfromfoodpreporserviceshouldberemovedassoonas 
possible.
3)Chloridesarepresentintablesalt,food,andwater.Householdandindustrialcleanersaretheworst 
typeofchloridestouse.
8stepsthatcanhelppreventrustonstainlesssteel:
1.Usingthecorrectcleaningtools
 Usenon-abrasivetoolswhencleaningyourstainlesssteelproducts.Thestainlesssteel’spassive  
layerwillnotbeharmedbysoftclothsandplasticscouringpads.Step2tellsyouhowtofindthe 
polishingmarks.
2.Cleaningalongthepolishlines
 Polishinglinesor“grain”arevisibleonsomestainlesssteels.Alwaysscrubparalleltovisiblelines  
onsomestainlesssteels.Useaplasticscouringpadorsoftclothwhenyoucannotseethegrain.
3.Usealkaline,alkalinechlorinatedornon-chloridecontainingcleaners
 Whilemanytraditionalcleanersareloadedwithchlorides,theindustryisprovidinganever  
increasingchoiceofnon-chloridecleaners.Ifyouarenotsureofyourcleaner’schloridecontent 
contactyourcleanersupplier.Iftheytellyouthatyourpresentcleanercontainschlorides,askif 
theyhaveanalternative.Avoidcleanerscontainingquaternarysaltsastheycanattack   
stainlesssteel,causingpittingandrusting.
4.WaterTreatment
 Toreducedeposits,softenthehardwaterwhenpossible.Installationofcertainfilterscanremove 
corrosiveanddistastefulelements.Saltsinaproperlymaintainedwatersoftenercanbetoyour  
advantage.Contactatreatmentspecialistifyouarenotsureoftheproperwatertreatment.
5.Maintainingthecleanlinessofyourfoodequipment
 Usecleanersatrecommendedstrength(alkaline,alkalinechlorinatedornon-chloride).Avoid 
build-upofhardstainsbycleaningfrequently.Whenboilingwaterwithyourstainlesssteel  
equipment,thesinglemostlikelycauseofdamageischloridesinthewater.Heatinganycleaners 
containingchlorideswillhavethesamedamagingeffects.
6.Rinse
 Whenusingchlorinatedcleanersyoumustrinseandwipedryimmediately.Itisbettertowipe  
standingcleaningagentsandwaterassoonaspossible.Allowthestainlesssteelequipmenttoair 
dry.Oxygenhelpsmaintainthepassivityfilmonstainlesssteel.
7.Hydrochloricacid(muriaticacid)shouldneverbeusedonstainlesssteel
8.Regularlyrestore/passivatestainlesssteel
