How to Deep Clean a House: The Complete Step-by-Step Guide

What Is Deep Cleaning?

Most of us stick to regular cleaning—vacuuming the floors, wiping down counters, doing the dishes. But sometimes, your home needs something more powerful: a deep clean.

So, what exactly does deep cleaning a house mean, and why is it important?

Deep Cleaning Goes Beyond Surface Cleaning

Unlike your usual tidy-up, deep cleaning is a top-to-bottom, thorough process that targets dirt, dust, bacteria, and grime in areas you don’t usually clean. It’s not just about making your home look clean—it’s about making it truly hygienic and healthier.

Here’s what sets deep cleaning apart:

• Cleans hidden spots: under furniture, behind appliances, inside cabinets
• Targets built-up grime: tile grout, oven interiors, window tracks
• Sanitises high-touch surfaces: light switches, door handles, remote controls
• Improves air quality: reduces dust, allergens, pet dander

If regular cleaning keeps things looking nice on the surface, deep cleaning restores freshness, hygiene, and peace of mind.

When Should You Deep Clean a House?

Certain times call for a deep clean, including:

• Before moving out of a rental property – helps secure your deposit
• After recovering from illness – reduces bacteria and viruses
• Seasonal refresh (spring or autumn) – resets your home after months indoors
• Before hosting guests or family gatherings – makes your home welcoming
• Preparing to sell a home – boosts appeal for buyers

A deep clean isn’t something you need to do weekly—but doing it a few times a year keeps your home healthier and more comfortable.

What’s Involved in a Deep Clean?

Deep cleaning covers every room, every surface, every corner. Some of the key tasks include:

• Scrubbing bathroom tiles & grout
• Cleaning inside the oven, fridge, and microwave
• Wiping down skirting boards and door frames
• Vacuuming behind and under furniture
• Washing walls and baseboards
• Descaling showerheads and taps
• Cleaning windows inside and out

It’s detailed work that takes more time and effort than a quick clean—but the results are worth it.

Many homeowners choose to deep clean themselves, while others prefer hiring a professional deep cleaning service to save time and ensure nothing gets missed. If it’s your first time tackling a deep clean, having a room-by-room plan makes it much easier.

In this guide, we’ll walk you step by step through how to deep clean a house effectively, covering all the essential tasks and pro tips to help you get the job done right.

Whether you’re deep cleaning before moving out, getting ready for guests, or just want your home to feel truly fresh again—you’ll find everything you need right here.

Supplies You’ll Need for a Deep Clean

Before you get started with your deep cleaning, it’s important to gather all the right supplies. Having everything ready in advance will save you time, keep you organised, and make the whole process more efficient.

Deep cleaning a house requires more than just your usual cloth and spray bottle. You’ll need tools and products that can tackle stubborn dirt, grease, and grime, as well as reach those tricky spots that don’t get cleaned regularly.

Essential Cleaning Supplies Checklist

Here’s a list of the must-have supplies for a thorough deep clean:

• Microfibre cloths – perfect for dusting and wiping surfaces without leaving streaks
• All-purpose cleaner – for general cleaning across multiple surfaces
• Glass cleaner – for windows, mirrors, and glass doors
• Degreaser – essential for cleaning kitchen appliances and extractor fans
• Bathroom cleaner or descaler – removes limescale from taps, showers, and tiles
• Scrub brushes – various sizes for tiles, grout, and stubborn spots
• Vacuum cleaner with attachments – for carpets, upholstery, and hard-to-reach corners
• Mop and bucket – for hard floors
• Protective gloves – to keep your hands safe from strong cleaning chemicals
• Garbage bags – for decluttering and disposing of rubbish as you clean

If you’re keen on using eco-friendly products, you can swap out chemical cleaners for natural alternatives like white vinegar, baking soda, and lemon juice—they’re surprisingly effective for many deep cleaning tasks.

Optional Extras to Make Deep Cleaning Easier

Depending on your home and cleaning goals, you might also find these tools helpful:

• Steam cleaner – great for sanitising floors, upholstery, and bathroom tiles without chemicals

• Lint roller – useful for fabric lampshades or upholstery
• Toothbrush or detail brush – perfect for cleaning small crevices and grout lines

Get Prepared Before You Begin

With the right supplies at hand, you’ll be ready to tackle every surface and corner, making your deep cleaning smoother, faster, and far more effective. In the next section, we’ll guide you step by step through each room so nothing gets missed.

Deep Cleaning a House: Room-by-Room Guide

Now that you’re armed with the right supplies, it’s time to tackle your deep clean! The best way to approach deep cleaning a house is by going room by room, following a structured plan so nothing gets overlooked. Below is a practical guide to help you clean each area thoroughly and efficiently.

Kitchen Deep Clean

The kitchen is one of the most used (and messiest) rooms in any home. A deep clean here focuses on tackling grease, food spills, and hidden dirt.

Key tasks for the kitchen:

• Clean inside and outside of the oven, microwave, and fridge

• Scrub backsplash and remove grease buildup
• Clean inside cupboards and drawers

Don’t forget to check the top of cabinets for dust and clean light fittings and extractor fans too!

Bathrooms need extra attention to tackle limescale, mould, and bacteria. A deep clean will leave everything sparkling and hygienic.

Key tasks for the bathroom:

• Descale taps, showerheads, and glass screens

Use a toothbrush or small brush to get into tricky corners and around taps for a professional finish.

Living Room Deep Clean

Your living space can collect dust, pet hair, and hidden dirt over time. A deep clean here refreshes the room and improves air quality.

Key tasks for the living room:

• Dust all surfaces, including skirting boards, shelves, and picture frames
• Clean behind and under sofas, chairs, and tables
• Vacuum upholstered furniture, including cushions and pillows
• Wash soft furnishings where possible (cushion covers, throws)
• Clean windows inside and wipe down window sills and blinds

If you have ceiling fans or pendant lights, use an extendable duster to safely clean them.

The bedroom is your personal retreat, so giving it a deep clean can make it more relaxing and healthier.

• Vacuum or steam clean the mattress
• Clean wardrobes inside and out
• Wash bedding, pillowcases, and duvet covers
• Vacuum under the bed and other furniture

Use a lint roller to remove dust from fabric lampshades and upholstered chairs.

Hallways and Entryways Deep Clean

Don’t forget these often-overlooked areas! A deep clean here makes a great first impression when guests arrive.

Key tasks for hallways:

• Dust skirting boards, shelves, and wall décor
• Clean doors, door frames, and handles
• Wipe down light switches and plug sockets
• Vacuum or mop floors
• Clean windows and mirrors if present

Following this room-by-room deep cleaning guide ensures every space in your home is thoroughly cleaned and refreshed. In the next section, we’ll cover common deep cleaning mistakes to avoid so you don’t miss anything important.

Common Deep Cleaning Mistakes to Avoid

Even with the best intentions, it’s easy to miss key areas or make mistakes during a deep clean. Knowing what to watch out for can save you time, effort, and frustration. Avoiding these common deep cleaning mistakes will ensure your home gets the thorough refresh it deserves.

1. Skipping High-Touch Surfaces

Many people focus on visible areas like floors and counters but forget to disinfect high-touch surfaces such as:

• Light switches
• Door handles and knobs
• Remote controls
• Fridge handles
• Cupboard pulls

These areas can harbour bacteria and germs, so be sure to sanitise them during every deep clean.

2. Forgetting to Clean Behind and Under Furniture

It’s tempting to clean around heavy furniture instead of moving it—but dust, crumbs, and dirt build up underneath. Move sofas, beds, and tables (if safe to do so) to vacuum or mop underneath. You might be surprised at what’s hiding back there!

3. Cleaning in the Wrong Order

A common deep cleaning mistake is working in a random order, which can create more mess. Always clean top to bottom—starting with ceiling fans, light fittings, and high shelves before tackling surfaces and floors. This prevents dust and debris from falling onto freshly cleaned areas.

4. Using the Wrong Cleaning Products

Not all cleaning solutions are suitable for every surface. For example, harsh chemicals can damage wooden floors or natural stone countertops. Always check labels and use the right product for each task—or opt for gentle, multi-surface cleaners when in doubt.

5. Ignoring Appliances and Fixtures

Deep cleaning isn’t just about visible surfaces. Appliances like the oven, fridge, washing machine, and dishwasher also need attention. Clean inside and outside these appliances, including filters and seals. Don’t forget bathroom fixtures like showerheads and extractor fans!

6. Neglecting Ventilation and Air Vents

Many homeowners forget to clean air vents, extractor fans, and filters. These areas collect dust and reduce air quality over time. During a deep clean, vacuum or wipe vents and replace filters if needed to keep your home’s air fresh and healthy.

7. Trying to Do Everything at Once

Deep cleaning a whole house in one day can be overwhelming and exhausting. Instead, break it down into manageable tasks or focus on one room at a time. Creating a schedule makes it more achievable and prevents burnout.

By avoiding these common mistakes, your deep cleaning will be more effective, efficient, and satisfying. In the next section, we’ll explore when it might be worth hiring a professional deep cleaning service to save time and guarantee results.

When Should You Hire a Professional Deep Cleaning Service?

Deep cleaning a house can be rewarding, but let’s be honest—it’s also time-consuming, physically demanding, and often overwhelming. While many homeowners tackle deep cleaning themselves, there are times when hiring a professional deep cleaning service is the smarter choice.

Here are the most common situations where it makes sense to call in the experts:

• Moving out of a rental property – Want your full deposit back? A professional deep clean ensures the property meets landlord or letting agent standards.
• Moving into a new home – A deep clean before you unpack ensures every surface is fresh, hygienic, and ready for your family.
• After renovation or building work – Builders dust and debris can linger in hard-to-reach areas; a pro clean will get your home spotless.
• Lack of time or physical limitations – If you’re short on time, dealing with health issues, or simply don’t want the stress, hiring help is invaluable.
• Preparing to host guests or an event – Ensure your home is welcoming and pristine without last-minute panic cleaning.
• Seasonal deep cleans – Schedule a professional clean once or twice a year to reset your home’s cleanliness and air quality.

Professional cleaners bring experience, specialised equipment, and attention to detail that’s hard to match with DIY efforts. They know where dirt hides and how to tackle stubborn grime efficiently and safely.

Deep Cleaning Tips and Tricks from the Experts

Want to make your deep cleaning more effective, faster, and less overwhelming? Over the years, professional cleaners have learned smart shortcuts and strategies that deliver better results with less hassle. Here are some expert tips to level up your deep clean:

Start with Decluttering

Before you deep clean, take a few minutes to declutter each room. Removing unnecessary items makes it easier to access surfaces, saves cleaning time, and helps you stay organised.

Clean from Top to Bottom

Always work from the highest surfaces (ceiling fans, light fixtures) down to floors. This prevents dust and debris from falling onto freshly cleaned areas and keeps your efforts efficient.

Use the “15-Minute Rule”

Break each task into 15-minute blocks. This prevents burnout, keeps you motivated, and makes even big cleaning jobs feel manageable. Set a timer and challenge yourself!

Focus on High-Impact Areas First

If you’re short on time, prioritise the areas guests or family use the most: kitchens, bathrooms, living spaces, and entryways. Leave less-used rooms for later or another day.

Let Products Do the Work

Don’t scrub harder—scrub smarter! Apply cleaners (like degreasers or bathroom sprays) and let them sit for 5-10 minutes before wiping. The dwell time breaks down grime so you don’t have to scrub as much.

Steam Cleaning Is a Game Changer

Investing in a handheld steam cleaner makes cleaning tiles, grout, upholstery, and even mattresses easier and chemical-free. Steam lifts dirt and kills bacteria effectively without harsh products.

Use Microfibre for a Streak-Free Finish

Microfibre cloths trap dust and leave surfaces shiny without lint or streaks. Use separate colours for different rooms (kitchen, bathroom) to avoid cross-contamination.

Don’t Forget the “Invisible” Spots

Some often-overlooked areas include:

• Behind radiators
• Top of curtain rails
• Under sink basins
• Extractor fan covers
• Door tracks and sliding mechanisms

Adding these hidden spots to your deep cleaning checklist ensures a truly thorough clean—and impresses landlords or guests alike!

With these expert deep cleaning tips, your house will feel fresher, healthier, and more inviting than ever. And if you’d rather skip the hassle and let professionals handle it, remember you can always book our professional deep cleaning service for guaranteed spotless results.
