All our Stainless Steel Bowls have a Frosted or Satin finish on the inside of the bowl.
• This is not a flaw but actually an extra process and a feature which adds substantial cost to the manufacturing process.
• Market research has shown that customers were/are tired of the flat polished finish that Stainless Steel comes with as it reminds them of cheap kitchen sinks.
The Satin finish refracts the light in the bowl and almost appears to glow and so doesn’t have the dull unpolished mirror effect of cheap and nasty products.
This will vary depending on what contaminants are in the water.
• Pure water leaves no residue at all and as such leaves no marks.
• However water from many Councils nowadays has high levels of Chlorine, Calcium, etc… and these chemicals leave residues when the water droplets evaporate.
• You will have noticed this when you have washed your car or any other surface and haven’t dried it properly.
For all Stainless Steel products (and in fact most other high gloss finishes) a way to alleviate this is polishing with an appropriate polish.
• What this in fact does is discourage the droplets from pooling which means the residues are less, more spread out and thus less visible.
Rusting & “Staining”
It is not true that Stainless Steel does not rust … just that it doesn’t rust brown.
• It in fact rusts very very quickly, in fact so quickly that it seals itself and as such the process stops quite quickly.
• The “rust” is actually from the Chromium and has a grey colour … hence why you sometime see Stainless Steel that looks matt or dull.
It is a good idea to polish all Stainless Steel surfaces just generally but especially so in a laundry.
• Laundry detergents more often than not have a high salt content which means they are highly corrosive (will cause metals to “rust”).
• The polish will also help to prevent iron contamination.
• This is when iron particles end up on or in the surface of the Stainless Steel and it starts to show reddish brown specks or even larger stains (commonly called tea-staining).
• If this occurs it is not the Stainless Steel that is the issue but rather how it has/is being treated.
It is vital to keep iron away from Stainless Steel.
• When we get called to “Rusting Tubs” it is generally (probably more accurate to say … ALWAYS) due to iron contamination.
• Sometimes people clean the Stainless Steel with Steel Wool … a major no no.
• Other times people clean areas with high iron contamination and dump the contamination into the laundry tub and don’t rinse it out properly.
• This can be from areas where perhaps angle-grinding has taken place or even just due to high levels of iron in the environment (especially nowadays).
• When iron contamination has occurred (rust marks are showing) then they need to clean with CLR and a nylon brush (wearing gloves!). Once all the iron contamination is fully removed the Stainless Steel needs to be polished (lots of products on the market for this).
It is vital to keep Acids away from Stainless Steel.
• Acids such as Hydrochloric acid will stain the surface of Stainless Steel and usually start more serious corrosion.
• Acids are often used to clean cement or mortar residues by builders and tiling contractors.
• On occasion we have found that these have been allowed into contact with the Stainless Steel Tubs – causing marking.
