starsan is an acid right? A strong one at that I assume.... so whatever you wouldn't want acid touching... don't let starsan touch.
 
My two cents....

I use a shot glass to measure my Star San prior to dispensing. During my last brew session I placed the Star San soaked shot glass on my brew rig's Corian countertop. I wiped the countertop down several hours later and noticed a white ring where the shot glass was placed :mad::mad:

After cussing myself, because I had read this thread earlier, I decided to try a Magic Eraser on the stain the next day. Whalla...it worked:):)

I may have been lucky since the stain was a new one, but perhaps it can work for you too.
 
I tried using the Magic Eraser - didn't work. Good idea though. I actually had my "one year walk through" with my housing developer and I tried to blame the stains on them... that didn't work either :) The developer sent his counter guy and he tried lots of different chemicals, etc... and nothing worked.

My wife and I plan on installing quartz or marble anyhow so it's not big deal. I don't even notice the stains anymore.
 
If you have installed a cast iron porcelain lined Kohler kitchen sink that's brand new you will see etched in dull spots that will destroy a high dollar sink. I used some cleaner on the old Kohler porcelain sink as a test item it was all chipped up and this is what I found. I did not have the balls to test the granite counter tops got over $5K invested in them alone. I will show a kitchen with everything that's perfect when this becomes a rental house. I also used stainless tank wash cleaner from a friends tank wash business as well their aluminum brightner cut with 50% water it ate the old porcelain sinks finish. Even concentrated 200, 300 or 400 grain vinegar my friend transports daily will etch into 304 stainless not alone a porcelain sinks gloss finish and especially a marble counter top. He had a custom made tank all 316 by Beal, a quality tank company. Kohler does not use low quality porcelian on their products last time I checked. Now if you take 3 or 400 grain as week control worked instantly spraying and killing weeds in sidewalk joints they will become a 1" thick foam layer until scrubbed with brush and neutralized many times but still leaving a white mark. Well I did a 4 flag section of the driveway ramp to make it blend in evenly. The granite cutoff sample took it like a champ but I will not tell the tenants this. I have seen burnt counters from overheated cast iron frying pans placed on the counters not alone cigarette butt burns.








One tenant two blocks away 56 years old was locked out so rips the basement storage and storm door off its big barn door hinges to break into the house thru the basement, yes I was home with spare keys less than a minute away on foot. Plastic float with plastic tube on the toilet flushwould stick once every couple months, he sprays WD 40 on everything including the walls and the 1" octagon tile floor, a 1913 house fully upgraded. dumb azz Engineer, dumber than a rock.
No smokings allowed in my rentals houses is right in the lease contract or any painting at all. I saw spilled paint coming from the sealed and locked off garage on both sides for a wood carving shop. His deposit loss will reflect damages. He sprayed acid base wheel cleaner on his Honda, guess what the acid did to the cement?











I had tar dripping off the windows on another rental spent $2,375 to have the tar chemically lifted and washed thruout the house walls a ceilings with a crew wearing pressurized maskes with gloves and scrub brushes then a vacuum system yes that bad. Roof leaked, plaster fell off the walls and radiused ceilings in sections besides black mold, cat pissed on the carpets. Window AC dripped wrecking the hardwood floor from dripping hence the oval carpet always there. At 6 year and counting on this restorarion a 1905 house with old world charm, new copper, central heating double panel "E" gas rated windows new roof and insulation, sewer and releveled. back of house to back building is 89' deep. I'm way off topic sorry just pissed when I hear tenant rights. It's not their $585,000 and $742,000 bank note and taxes they're paying on these invenstments so why take good care of the rentals? This is why they live in rentals. Meds and flu got me rambling mods remove this last section if my reply is deemed necessary. I respect your openions. Just found our thursday the tenant used / removed the french drain cap that goes around the property to hose off the cement of grass cuttings, gravel, leaves and mud before it rains. The rubber cap is screwed on with a worn gear stainless clamp just below grade so now the 1/2" wall by 48" diameter 80 gallon tank and 3/4 hp sump pump are jammed up with GFI tripped. Yes a steel cover with a layer of bricks covering the sump system for the trash cans to sit on and it's raining. I'm dead off my butt with the flu too sick to die.
 
Maybe it could take a stain out of white carpet? Some very red juice got spilled by the former tenant's friend.....I was there, but I rented the place anyway....
 
iodine will also take the color out of things, so your still not safe (get some on your black shirt). Depending on the original color, it may add color. (skin)

Yup, I came in here to post this.

I have a darker brown T, that now has some scattered orange spots on it from the iodophor.

Blotting any wine stains with oxyclean gets them right out. My wife was helping me make a wine kit one day during which she was supposed to pour the concentrate into the bucket. She missed the bucket and hit our white wall. After me pissing and moaning we just damped a towel with oxyclean and it got the red out right away. You can still see a discoloration where the wine spilled on the wall but that is manageable.

I had the glass of red wine spill on my white carpet... and bed... again blotting it with oxyclean got it right out.

I would be hesitant to use Starsan on anything but my brewing equipment.
