Domakihub Deep-Clean a Mattress: Baking Soda & Stain Removal Guide
A seasonal routine to deodorise, treat stains, and refresh mattresses between guests — for Greek holiday homes, rentals, and hotels.

A clean mattress is one of the first things guests notice — and one of the last things most owners actually clean properly. The video above walks through the full process using a vacuum cleaner, baking soda, and hydrogen peroxide; this article breaks each step down with timing and quantities suited to the Greek climate, where high summer humidity and heavy rental turnover demand a more rigorous routine. Whether you manage a single holiday apartment in Crete or a portfolio of villas in the Peloponnese, running this reset at the start and end of each season will extend mattress life and protect your reviews.
Why Greek Rental Mattresses Need More Than a Sheet Change
Greece's coastal summer climate — warm nights, salt air, and humidity that climbs above 70% between July and September — creates ideal conditions for dust mites, mould spores, and odour-causing bacteria to settle into mattress foam. A standard linen swap does nothing to address what has accumulated below the surface over a busy rental week.
Hotels and holiday-rental operators face an additional challenge: guests expect hotel-grade hygiene but rarely leave enough turnaround time between bookings for a full airing. Building a structured two-stage clean (vacuum and deodorise, then spot-treat stains) into your changeover schedule means you can complete it in under two hours without professional intervention.
What You Need Before You Start
Gather your supplies first so the process runs without interruption. You will need a vacuum cleaner with an upholstery attachment, plain bicarbonate of soda (baking soda), 3% hydrogen peroxide solution (available at any Greek farmakeio), a spray bottle, cold water, a few clean white cloths, and optionally a few drops of lavender or tea-tree essential oil to blend into the baking soda. Avoid hot water throughout — heat sets protein-based stains such as sweat and blood rather than lifting them.
If the mattress has a removable cover, strip and machine-wash it before you begin. Work in the morning if possible so the mattress has the full day to dry before the next guest arrives, and crack windows wide to encourage airflow — something easily done in most Greek properties during the shoulder seasons.
The 5-Step Seasonal Deep-Clean Routine
- 1
Strip, vacuum, and beat out loose debris
Remove all bedding and the mattress protector. Fit the upholstery nozzle to your vacuum and work methodically from the head of the mattress to the foot in slow, overlapping stripes, paying extra attention to seams and tufting channels where dust mite waste and dead skin cells accumulate. Flip the mattress and repeat on the underside. This first pass removes the loose particulate layer that would otherwise get locked in once you apply any liquid.

Apply baking soda and leave it to work
Sift a generous, even layer of baking soda across the entire top surface — roughly half a cup per single mattress or a full cup for a double. If you want a subtle scent, mix five drops of lavender essential oil into the powder before sprinkling. Leave the baking soda on for at least one hour; if the mattress is particularly odorous or has been in storage, extend this to three hours. The alkaline powder neutralises acidic sweat compounds and absorbs residual moisture. Keep windows open during this phase.

Vacuum off the baking soda thoroughly
Once the dwell time is up, vacuum the entire surface again using the same slow, overlapping technique. Work from the centre outward and then along all seams to capture every particle. Leaving baking soda residue in the fabric can attract moisture later, so be methodical. When you are satisfied the surface is clear, vacuum the underside of the mattress once more before returning it to the base.

Treat stains with a hydrogen peroxide solution
For any visible stains — yellowed sweat marks, food, or biological fluids — mix one part 3% hydrogen peroxide with two parts cold water in a spray bottle, then add a small squeeze of washing-up liquid and shake gently. Spray the stained area until just damp (never soaking), then blot firmly with a clean white cloth, working inward from the edges of the stain to prevent spreading. Repeat until the mark lifts. For older set-in stains, make a paste of hydrogen peroxide and baking soda, apply directly, leave for fifteen minutes, then blot away. Let the treated area air-dry completely before making the bed; in Greek summer conditions this typically takes thirty to forty-five minutes with open windows.

Protect, reassemble, and schedule the next clean
Once the mattress is fully dry, fit a high-quality waterproof but breathable mattress protector — this is your single best investment against future staining and is far easier to launder between guests than repeating a deep clean. Remake the bed with clean linens and note the date of the clean on a simple maintenance log. For Greek holiday rentals, plan for a full deep-clean at the end of October before winter closure, again in late March before the summer season opens, and a mid-season baking-soda refresh in July for heavily booked properties.

FAQ
- How often should I deep-clean mattresses in a holiday rental?
- For a busy Greek holiday rental, do a full deep-clean (vacuum, baking soda, and stain treatment) at least twice a year — once before the season opens in spring and once after it closes in autumn. For properties with high weekly turnover from June to August, add a lighter mid-season refresh: vacuum and a baking-soda application without the stain step. This prevents odour and allergen build-up from becoming a structural problem that no amount of cleaning can fully reverse.
- Is hydrogen peroxide safe to use on all mattress types?
- A 3% hydrogen peroxide solution (the standard pharmacy concentration sold across Greece) is safe on most foam, spring, and hybrid mattresses when diluted with water and blotted rather than soaked in. Avoid using it on memory foam if the manufacturer's label explicitly prohibits moisture, as very dense foam can trap liquid deep inside where it will not dry. Always test on a small, hidden corner first and never use undiluted hydrogen peroxide, which can bleach fabric covers.
- Can I speed up drying time in humid Greek summer conditions?
- Yes. Point a floor fan directly at the treated surface, leave balcony doors and windows fully open, and if you have an air-conditioning unit, run it in dehumidify mode rather than cooling mode — this removes moisture from the air without lowering the temperature so sharply that it slows evaporation. Avoid making the bed until the mattress passes the palm-press test: press your hand firmly onto the treated area and hold for five seconds; if you feel any coolness or dampness, give it more time. Rushing this step is the main reason mould develops under freshly changed sheets.
