Oh no! what have I done! brown stain on the floor.. help!

I was doing some 16mm cine film developing yesterday - it was old discontinued Ilford FP4 stock and I had no idea what to use for developer or the times etc... Anyway, beside the point I ended up using some D-19 I had from some earlier reversal developing, I had Sodium Thiocyanate mixed with it which makes it basically D-94 ... I was also using Jessops stop bath (with the colored exhaust dye stuff in it) and Ilford rapid fixer ...

I dont specifically remember spilling any of the above on the floor but this morning there is a big ol' brown stain in the linoleum that wont budge for anything ... Other household members not impressed ...

Is this a common color for spillage of any of those chems ? and more importantly >> if so, are there any remedies ?

(btw, film came out great)

Now i don't know chemically if this could be a bad Idea, But..
you can make a past of peroxide and Baking soda - "i think" and you apply that to the stain and cover it with plastic. then you leave that for a few hours. that's a cure for counter top stains. it may be iffy on the floor.

I use denture cleaning tablets for those pesky brown stains in my Nova. You may have to create some kind of pool around the area of the linoleoum (wood+silicon to seal), pours some h20 and some of those cleaning tablets. Let it sit for a night. Write your will if you are married. Then check it next day.

Hrm or stain the rest of the floor til the whole thing is a solid shade of brown and just claim you photographically designed the kitchen that way... (before someone can blurt out 'what you do ... miss the can?')

no denture tablets on hand, but I'll try the peroxide and baking soda trick ...

its the same floor in which a thermometer blew up all over a few years back also... seems to really suck in anything with dye in it - but the blue blobs were evenly enough distributed down there that it looked almost normal...

BTW: never ever put a photography thermometer into near boiling water... your immediate reaction upon seeing it rocket right to its limit is pull it out, which is when it explodes glass and noxious chemicals directly into your face leaving a human shaped shadow in the blue blob distribution on the wall which was thankfully much easier to clean than this damn floor

So use chemistry lab thermometer My one goes to 200 C, it is made from glass (good thermo isolator) and is long enough to handhold it in a boiling water.

Best regards & luck with removing the stains

Or hold the end near a gas flame in a stupid attempt to get rid of air bubbles. It has the same effect!

Nick,
Any results yet? I have the same type of stain on my linoleum floor and tried the baking soda and peroxide paste overnight with no effect. Guess I'll try the denture cleaner tonight.

Oh no! what have I done! brown stain on the floor.. help!
