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.
