cleaned an office last week where a delivery driver had dropped fish guts onto an offices carpet tiles whilst carrying it through the wrong entrance. I got there about 4 hours after it had dropped and the customer had used sodium bicarb to absorb some of the liquid as well as lots of paper towels.

it stunk when i got there. i used a cherry deodoriser (3 times normal strength) as well as solutions HD. gave about 10 minutes for the product to work and then blasted the spot clean with as much heat as the magma heater can chuck out at 400psi. i rinsed the area (about 1 square meter) over and over and over until i was confident it'd be washed through and left with the place smelling beautiful.

flast forward to today customer says tehre is still a small amount of smell lingering and would another clean and happy to pay (courier paying).

any suggestions anything else i can try? and advice why the first time i didn't all come up? visually there is nothing there, however it just still smells

Something not quite right about this problem... smells a bit fishy to me....

[Jim_77]

sorry

Try an enzyme product maybe.

They probably made it worse by washing it themselves. With no means of extraction they will have washed it into the floor beneath which I would imagine will be a concrete slab.
As Jim says I would use an enzyme product such as Enzall or Pre-enzyme solution (others are available) Mis it hot and soak the affected area so it penetrates whatever is beneath the carpet. Allow to dwell for 15 minutes then rinse out thoroughly. A topical coating with a residual anti microbial like Formula 429 would help with any remaining problems.

Here was me thinking M Power would get recommended since its a MARINE problem.

Maybe these are fresh water fish guts.

I had a problem like this were a kid had spewed fishfingers up lol it stunk i cleaned it but the smell came back so i spotted area with urine nutraliser and it solved the problem maybe worth a try.

Lift the carpet tiles through them away or if not power wash them , deep. Clean the floor underneath the tiles
Fish mush and the smell is about the hardest to get rid off.  Best of luck
