Old urine stains on wool carpet

[Andersonx3]

As above, anyone have any tips on how to remove? The stains are old - so anything that needs to be done immediately after the accident would be no use. We've had a professional carpet cleaner in, so the stains are 'clean' but they have discoloured the carpet, which is cream, as the urine has dyed the wool.

Are the stains darker? Assuming it's wrecked could you try bleach?
(that might be a stupid idea)

Or could you wee all over the carpet so it just becomes 'patterned' :o

@StealthPolarBear yeah they're typical piss colour. I've thought about bleach but also thought it might be an awful idea 😂

@2020BetterBeBetter thinking about it 🤨

@2020BetterBeBetter wrong tag - apologies!

Bumping for some actual advice rather than my ramblings :)
