Spillage and Odour Removal Treatment

Spillage and Odour Removal Treatment

80% of cars we treat for odour have already been valeted, shampooed and treated with odour bombs. The smell returned because the source wasn't found. We find it.

Odour lives where a valet can't reach - inside door seals, under seat runners, in HVAC ducting, behind trim panels. Our process starts at the source: strip, locate, treat the substrate, then seal. Masking products buy a few days; eliminating the source ends it.

Spilt milk clean-up on an Audi RS5. The seat came out and there was rotten milk under the carpet -- adding more water just dilutes and spreads it further. This is why shampooing alone often isn't enough.

Find the source - treat the whole interior

Most odour treatments that don't work share the same reason: they treated the smell, not the source. Shampoo, odour bombs and air freshener can suppress a smell briefly -- if any trace of the substance causing it remains, in seat runners, behind dashboard trim, in carpet underlay or under rear carpets, the smell returns. Our first job is to locate what's producing the odour. Once the source is removed, we treat the whole interior. Air fresheners follow treatment; they don't replace it.

If you've had a spill, call us before you wash it. Diluting milk with water spreads it through seat foam and carpet underlay, where it ferments and becomes much harder to extract. Petrol and diesel float on water and can permeate plastic trim and bare paintwork. The sooner we deal with it, the simpler the job.

The treatment also depends on what caused the smell. Smoke and tar need ozone treatment and fogging to reach surfaces you can't clean by hand. Biological contamination -- milk, pet urine, mould -- needs enzyme-based products that break down the organic matter rather than masking it. Chemical spills like petrol or paint need extraction and neutralisation before anything else. The right approach for one won't work for another, which is why we assess before we treat.

Odour Removal FAQs

Why does cigarette smoke smell come back after valeting?

Standard valeting doesn't reach all the sources. The smell comes from ash -- which settles into steering column trim, seat runners, seat belt winders and gaps behind the dash -- and from tar, which coats every hard surface the smoke touched. Shampoo and fragrance mask it briefly; once the air freshener fades, the ash and tar are still there. We strip back trim to clear the ash, and use ozone treatment and fogging to seal tar on surfaces we can't reach by hand.

Why does the smell keep coming back after shampooing?

Shampooing treats the surface. Most persistent smells are in the foam under seats, in carpet underlay or on hard surfaces hidden from view. Until the source is gone from those locations, the smell returns -- especially on warm days when bacteria are most active. 80% of cars we treat have already been shampooed and treated with odour bombs before they arrive.

I've just spilled milk -- what should I do?

Call us before you wash it. Diluting milk spreads it through seat foam and carpet underlay, where it ferments and becomes much harder to extract. We remove the rear carpet -- and sometimes the seats -- to find and treat every contaminated area. The sooner we start, the more straightforward the job.

Do you work for insurance companies?

Yes. We carry out odour removal and decontamination for insurers, including chemical spills, biological incidents and rodent infestations. We can advise on whether your situation is likely to be covered before you make a claim.

How much does odour removal cost?

It depends on what the smell is, how long it's been there and how far it's spread. A fresh spill costs less than a smoke-damaged car that's been valeted twice with no result. Call us and describe the situation -- we'll tell you what we think is involved and what it's likely to cost before you book.

Kieran

Took my A4 converitable that I have nearly finished restoring, for a refurb of the the blue roof, or at least thats the colour that it should have been. After the boys at New Again had worked their magic, it looked almost brand new, with the colour restored and all the mould and algae disappeared. Great job

Jon

Accidental clean dealt with promptly and efficiently. Can highly recommend Gary and his team at New Again. Outstanding customer focused service. Thank you

David

After a can of fence paint exploded in the heat all over the rear footwell and seats of my BMW I headed down to Gary at New Again. From the start Gary was very honest and informative about what to expect and potential costings to remove the paint from carpets/seats/air vents/speakers...it was everywhere. Gary and the team sent me videos with every step of progress from start to finish and communication was very good . On collecting the car a few days later I am very happy with the job the guys have done .

Graeme Lillywhite

I had just bought a car which I soon discovered had a terrible smoke odour which had very quickly returned days after buying the car. I was expertly guided throughout my initial meeting and given a number of options to consider. 5 months after the completion of the work, the odour has not returned. Fantastic team and clearly great at their jobs!

Lily Edwards

I hadn't even had my last car long before my kids made it a complete mess. Every time I cleaned it, they would spill something and mess it up. When we needed something bigger and were going to have to sell the car, I didn't know what to do. Some of the offers I got before I went to New Again weren't even close to what I sold it for afterwards. Their services were fantastic and better than I could have hoped for, the car looked amazing in the end! They took care of all the mess on the upholstery, the spills, the smell, and even the scratches on the outside. In my opinion, they are absolutely worth every penny.

Dean Webb

After 10ltrs of paint spilt in my 4 month old car I was devastated. Emailed New Again over night and a reply 8am following morning. 3 young guys worked on car for almost 3 hours and WOW... what an amazing job they done. I can't say how much these guys are a credit to this business - professional & polite at all times. I drove all the way back to East London with a smile on my face.

Adam Ford

I drove the car away relatively confident the smell has gone and can safely say that as of 23:19, some 6ish hours later, the car smells just fine. Fingers crossed it lasts! In summary: brilliant place, great service, fair pricing and very thorough good workmanship. Definitely recommended.

Craig Allen

Sort notice clean of a seat which was sicked on. The guys were all accommodating and happy to fit me in. Over the moon with the result, Thanks guys.

Steve Hobern

Absolutely fantastic service! After spilling 5ltrs of weatherproof gloss all over the interior of my car, my car was returned to me without a single trace of paint anywhere to be seen. Very friendly people, would definitely recommend.
