Short answer
Nectar's FAQ doesn't mention steam. It says to spot clean 'with a damp cloth and mild detergent or hand soap, taking care not to let liquid reach the underlying foam layers,' and 'Under NO circumstances should the cover be removed from any Nectar mattress. Removing the cover will void all warranties.' Our dry-vapor method is our own, not a Nectar exemption; check your warranty terms first.
Key terms used on this page
- Care instructions (manufacturer care guidance):
- What a manufacturer publishes about cleaning its product: a sewn-in label, a care web page, a help-center article or a brand blog post. They carry different weight. A sewn-in label or a product-care page speaks for a specific product; a blog post often gives general advice about many mattress types. On this hub we name the document type for every quote.
- Memory foam (viscoelastic foam):
- An open-cell, slow-recovery polyurethane foam that softens with body heat and conforms to pressure. Because its cells are open, liquid can travel into it, and because it is dense and insulating, it is slow to dry.
- Warranty exclusion:
- A condition a manufacturer says its warranty does not cover. Purple, for example, says 'damage from the sun is excluded from warranty coverage,' and Tempur UK says soaking 'will also invalidate your guarantee.' Only the manufacturer can decide a claim.
- Dry-vapor steam:
- Steam made in a sealed, pressurized boiler and released through a hose and nozzle as hot vapor with a low liquid-water content. In the vendor specifications we reviewed, professional units are rated from 80 psi (Ladybug 2350) to 150 psi (Daimer), with stated boiler temperatures from about 345°F (Optima) to 360°F (Daimer); these are maker claims. Daimer describes its steam as about 5% water or less and Vapor Clean claims 'just 5-6% moisture'; that is a vendor claim, not an independent standard.
- Adjustable steam output:
- A control on some commercial steam machines that sets how much steam reaches the tool. For example, Vapor Clean describes its Magnum XP (with vac) as having a 'Fully Adjustable Steam Regulator' and a 'Pressure Regulator 0 - Full Range' (maker's claims). We don't publish settings; the technician chooses them for the material.
- Pass speed:
- How fast the steam tool moves across the fabric. A faster pass gives the fabric less time under the tool, so less heat and less condensed water reach any one spot. Purple's general guide makes the same point for home steamers: move 'without leaving it in one spot for too long.'
Nectar makes memory foam and hybrid mattresses. Its FAQ doesn't mention steam, but it contains some of the strongest warranty language we read: removing the cover "will void all warranties." Its cleaning advice keeps liquid away from the foam.

1. What the manufacturer actually says
The source is Nectar's FAQ page (no date shown; accessed 2 October 2026).
The cleaning answers sit under "Can I clean Nectar's Cover?" and the cover-removal answer in the same FAQ.
On the cover and warranty:
"Under NO circumstances should the cover be removed from any Nectar mattress. Removing the cover will void all warranties."
On spot cleaning:
"For spills and light accidents, we recommend spot cleaning the cover as soon as the spill or stain occurs with a damp cloth and mild detergent or hand soap, taking care not to let liquid reach the underlying foam layers."
On why:
"We don't advise removing the mattress cover as this will void the warranty and as the underlying foam layers may get damaged in the process."
On protection:
"We strongly advise the use of a stain and water-resistant mattress protector (such as the ones we have available for purchase on our site) which may be removed and laundered from time to time."
2. Does it mention steam?
No. The FAQ doesn't mention steam. It does say liquid should not "reach the underlying foam layers," which is the variable we manage on any foam bed.
3. Does it mention dry-vapor steam?
No. Nectar's page never names dry-vapor steam. Its cautions on water, soaking, chemicals and covers still apply.
4. The restrictions it states
| Variable | What Nectar's page says |
|---|---|
| Water | "a damp cloth and mild detergent or hand soap" |
| Soaking | "taking care not to let liquid reach the underlying foam layers" |
| Heat | Not stated |
| Steam | Not stated |
| Chemicals | Only "mild detergent or hand soap" named |
| Covers | "Under NO circumstances should the cover be removed"; doing so "will void all warranties" |
Nectar ties the warranty directly to the cover. That is the only care rule on the page with a stated warranty consequence.
Every brand's restrictions sit side by side in the compatibility guide.
5. How dry vapor differs from wet cleaning
Nectar's stated concern is liquid reaching "the underlying foam layers."
Dry vapor leaves far less water than carpet-style extraction, but heat and moisture are separate variables.
Vapor Clean claims the Magnum XP runs at "just 5-6% moisture" (maker's claim, not our measurement).
The EPA advises drying wet materials within 24 to 48 hours; the hub's drying note explains why.
6. Sleep Sanitation's professional interpretation
This section is our view, not Nectar's.
Nectar's guidance is the default for owners: spot cleaning the cover right away with a damp cloth and mild detergent or hand soap, keeping liquid out of the foam, a removable protector, and never removing the cover.
Our position: we can sanitize Nectar mattresses (the CDC's sense, not disinfection). On a Nectar we never unzip or remove the cover, use no detergent, and keep passes short so moisture stays in the cover fabric rather than reaching the foam.
We run three Italian-made Vapor Clean machines, the Magnum XP, ProV 350 and Pro6 Duo, at low steam output.
Passes stay quick and light. We don't unzip covers, soak the bed, or use bleach or solvents.
This is our method, not a Nectar exemption, and Nectar hasn't reviewed it. Check your warranty terms before booking.
Nectar's FAQ states that removing the cover will void all warranties; it says nothing else about cleaning and warranty.
Not legal advice; if you're unsure, ask the manufacturer.
Nectar's own cleaning routine
- Act fast. Spot clean "as soon as the spill or stain occurs."
- Damp, not wet. A damp cloth with mild detergent or hand soap.
- Protect the foam. Keep liquid out of the foam layers.
- Protector. Stain and water-resistant, removable and launderable.
Other care points on Nectar's page
On protectors:
"We strongly recommend the use of a stain and water-resistant mattress protector (such as the ones we have available for purchase on our site), which may be removed and laundered from time to time."
On the cover:
"Keeping the cover intact will help protect the integrity of the mattress so that you may enjoy amazing sleep for years to come."
On foundations:
"We do not recommend placing your mattress on the floor, plastic base, or any home-made foundation."
Before a visit to a Nectar bed
Nectar's rule on the cover is the strongest we found: removing it "will void all warranties." Our technician never unzips a Nectar cover, even to inspect a stain, and treats everything from the outside.
Nectar also says it does not sell replacement covers, which is one more reason to keep the cover intact. If the bed is a Nectar Hybrid rather than the all-foam model, mention it; the coils change how heat and air move through the bed, though the cover rule is the same.
Nectar also warns against putting the mattress on the floor, a plastic base, or a home-made foundation. Those warnings are about support, but a bed on the floor traps moisture underneath, so tell us where the bed sits; it changes how long we leave the bed to air after the visit.
Between visits, the protector Nectar recommends does most of the work. Wash it with the sheets, and the cover underneath stays cleaner for longer.
Common misreadings
"The cover has a zipper, so it can come off." Nectar says "Under NO circumstances" should it be removed.
"Not mentioned means permitted." No. Nectar doesn't mention steam either way. Silence is a gap in the guidance, not a permission.
How Nectar compares with the other brands we checked
Nectar is not among the five brands whose care pages mention steam. None of the 21 pages we checked mentions dry vapor.
Nectar's page addresses 4 of the six variables in section 4; it is silent on heat and steam.
Its water wording, for comparison: "a damp cloth and mild detergent or hand soap".
The compatibility guide lines up all 21 pages, from Tempur-Pedic's strict water rule to the brands that tie care to warranty.
Your label and warranty
Your sewn-in label speaks for your model and outranks Nectar's web page. Use the hub's label checklist before any cleaning.
Where this fits
- Materials: memory foam, cooling gel foam.
- Related brands: Casper and Purple; the full table is in the compatibility guide.
- Visits: read our process, check pricing, or schedule a visit.
Related guidance and background
How other manufacturers word the same issue, for comparison:
- Avocado. "Steam cleaners are not recommended because their excessive heat can over-bake the organic latex" (Avocado).
- Tempur (UK). "Do not steam-clean or dry-clean the TEMPUR Material" (Tempur UK).
- Tempur-Pedic (US). "TEMPUR® material should never become wet" (Tempur-Pedic).
What we don't know
- Heat. The FAQ says nothing about heat.
- Full warranty text. We quote the FAQ, not the warranty document.
- Dry-vapor steam. Nectar hasn't addressed it on the page we quote.
- Changes. Care pages change; we read Nectar's page on 2 October 2026 and will update this page if it changes.
