If you're switching away from a scented cleaner because of chemical sensitivity, that's actually a smart move — and the good news is you don't have to compromise on effectiveness. The only products that permanently eliminate pet odours are enzyme-based cleaners. Everything else — sprays, powders, scented formulas — just masks the smell, which means your dog will sniff out the exact same spot and go again. Before I point you to the right fragrance-free option, a few quick questions: which surface are you dealing with — carpet, hard floor, sofa? Is this urine, or something else? And are these fresh accidents or stains that have had time to set in?
It's carpet mainly, urine from my Airedale. He's 7 and still has the odd accident overnight. Some are fresh but a couple of patches have been there a week or so. I've been using a lavender-scented spray and it's been triggering my migraines.

That makes complete sense — a lot of those scented pet sprays have quite aggressive fragrance loads, and if you're migraine-prone they can be genuinely miserable to use. The lavender version won't be breaking down the urine at a molecular level either, which is why your Airedale keeps revisiting those patches. For a 7-year-old dog with occasional overnight accidents, the set-in stains are the ones that need the most attention — urine that's been in carpet fibres for a week has started to crystallise, so you need a strong enzymatic formula to fully break it down. Is he otherwise healthy? Sometimes increased accidents in older dogs are worth a vet mention, but occasional overnight ones in an Airedale at 7 aren't unusual.
Yes, vet checked him out recently, all fine. He just sleeps heavily and doesn't always wake himself up in time. Good to know about the crystallising — I had no idea that was happening.

Good — worth ruling out, but sounds like straightforward deep-sleep accidents. For your situation, I'd go with Simple Solution Fragrance Free Stain and Odour Remover. It's a proper enzyme-based formula with no added fragrance at all — no masking agents, no perfume, nothing that should trigger a migraine. It works on both fresh stains and set-in ones, though for the week-old patches you'll want to saturate the area, let it sit for at least 10 minutes, and blot rather than scrub. The enzymes need time and moisture to get into crystallised urine. It's widely available on Amazon UK, comes in a good-sized spray bottle, and is safe around dogs once dry. It's the one I'd hand someone in your exact situation without hesitation.
That sounds exactly right. Is there anything specific I should do differently for the older set-in patches versus the fresh ones?
inparticular.ai
Yes — fresh stains, blot up as much as you can first, then spray and leave for 5–10 minutes before blotting dry. For the set-in patches, you need to re-wet them first with a little cold water before applying the enzyme cleaner. This reactivates the dried urine salts and gives the enzymes something to work on. Saturate properly, cover with a damp cloth to slow evaporation, and leave it for 15–20 minutes. Don't use heat — no hairdryer, no steam cleaner — because heat bonds urine proteins to fibres permanently. Once it's dry, if you can still detect a faint smell, do a second application. Two treatments on a week-old stain is normal, not a sign the product isn't working.
Really helpful, thank you. I'll order the Simple Solution Fragrance Free today.

Perfect choice for your situation. Once those old patches are fully treated and the smell is gone, your Airedale should stop targeting those spots — that's the real payoff of using a proper enzyme cleaner rather than a masking spray. Good luck with it.
