Carpet stain removal advice

Maybe lemon juice and salt? But you need to soak it into the carpet, let it sit then blot it out with a white cloth. No rubbing or the stain could spread.

Timely post as i had a professional carpet cleaner here today as I needed a sofa cleaned and lots of stair carpets I'd also spilt a hot cup of tea on the landing which was awful. He was great and very thorough there is no sign of the tea stain you'd never know it was there he also left us with a bottle of his own stain remover and cleaned the door mats for free. Its not cheap but if you can get a professional in.

Rust stains on wool carpet can be really tricky, especially if the usual home remedies haven’t made a dent. Since you’ve already tried vinegar, bicarb, and salt, I’d avoid WD40 — it can leave an oily residue that’s hard to remove from natural fibers.

You might want to try a product with oxalic acid, which is often used for rust removal on wool and delicate materials. Just be sure to test it on a hidden patch first. Another option is to gently dab lemon juice on the spot, let it sit for a few minutes, then blot with cold water — sometimes that can lighten the stain a bit.

If nothing works, it might be time to call in a professional carpet cleaner. I’ve seen teams like Colorado Stain Master handle old rust marks with specialized equipment and spot treatments that don’t damage the fibers. It’s worth it if you really want to save that carpet.

Sage, WD40 make a non-oil-based formula. I have tried Vanish, use it a lot.

Nannynoodles, I have ordered the HG one. Will keep people posted.

Thanks to all.

WD40 is oil based and will leave a stain.

Try Vanish.

WD40 might work, it works on removing makeup.

We swear by Stikatak carpet stain remover, which is stocked by our local independent hardware store, but is generally only available online.
Can't promise it will work, but it's never let us down yet.

HG do a Stain Away Rust which might be worth a try but I have always found Dr Beckman’s works a treat, have you let in soak in and done it a couple of times?
Other than that could you put a rug or bean bag or something over it?

I've used Ammonia - well diluted on carpet stains .
Don't know if it will work on rust .
I hate the pong and it makes your eyes water .
