This is a specific conversation about Pet stain and odour removal — what actually works — ask about yours and get one honest answer for your exact situation.

Foster kittens at six weeks are still learning, so multiple accidents a day on soft surfaces like bath mats and towels is completely normal — but you do need to clean them properly or the smell will keep drawing them back to the same spots. The only products that permanently eliminate pet odours are enzyme-based cleaners. Everything else — baking soda, white vinegar, standard fabric spray — just masks the smell temporarily, and kittens have a far sharper nose than you do. So: are the mats and towels going in the washing machine, or do you also need something you can spray and leave on the mat in place? And are the stains mostly urine, or are you dealing with faeces too?
Mostly urine, a couple of poo accidents too. The towels go in the wash but the bath mat stays down so I need something I can spray on it directly. Some stains are fresh, some have dried in already.

Good — that gives me a clear picture. For the bath mat, I'd go with Simple Solution Extreme Pet Stain and Odour Remover. It contains a professional-strength enzyme formula specifically designed for urine and faeces on fabric surfaces, and it handles both fresh and set-in stains. Spray it on, work it lightly into the fibres, and let it sit for at least ten minutes before blotting — don't scrub, as that spreads the proteins deeper into the mat. For the set-in stains, you may need a second application once the first has dried. One thing worth knowing: at six weeks, kittens' urine is less concentrated than an adult cat's, so it does respond well to enzyme cleaners even when it's dried in. How big is the bath mat — are we talking a small one or something chunky that needs a decent amount of product?
It's a medium-sized one, maybe 50x80cm. And should I be doing anything differently for the towels going in the wash?

For the towels, add a capful of Simple Solution Laundry Odour Eliminator directly to the drum along with your normal detergent — standard detergent alone won't break down the urine proteins, so towels can come out of the wash smelling fine to you but still detectable to the kitten. Wash on a warm cycle rather than hot, as very high heat can actually set the proteins before the enzymes have time to work. Once the towels are clean and dry, keep them off the floor until the kittens are more reliably using the tray — at six weeks they're still building the habit, and a soft, familiar-smelling surface on the floor is just too tempting. Does the kitten have easy access to a low-sided litter tray? At this age, the tray sides matter a lot.
Yes, I've got a shallow tray right next to the bath mat actually. They just don't always make it in time.

That's reassuring — proximity is exactly right. The missing-the-tray issue at six weeks is almost always about timing rather than preference; their bladder control just isn't fully developed yet. As long as the mat smells genuinely clean (which the Simple Solution will achieve) rather than just masked, they won't start to associate the mat itself as a toilet spot, which is what you're trying to prevent. Stick with the enzyme cleaner consistently for the next few weeks and you should avoid any ingrained habits forming. You're doing the hard bit right — most people use the wrong cleaner and then wonder why the kitten keeps going back.
Really helpful, thank you. I'll grab the Simple Solution spray and the laundry one.
inparticular.ai
Perfect combination for the job. The spray handles the mat in place, the laundry additive sorts the towels properly. Both are on Amazon UK and reasonably priced for the volume you get — at multiple accidents a day you'll get through it, but it should last a few weeks. Good luck with the foster — six weeks is a demanding age but they come on fast.
