Cleaning a Bathroom Sink

It’s not as challenging as you would expect to clean your bathroom sink. Gathering all of your necessary stuff ahead of time will be beneficial, so do so first.

Step #1: Rinse and Wipe

Do you have all you require? Great!

An initial wipe and rinse is the first step in any basin cleaning procedure. You should use warm water to dampen a sponge or rag. It doesn’t have to be hot; just make sure it’s not cold!

Wipe down the sink’s edges to remove any stray hairs, dirt, dust, or debris. As you get closer to the drain, use smaller and smaller circular wipes. When your sponge or cloth becomes dirty, make sure to rinse it with clean water from the tap.

When you’ve finished wiping and rinsing the sink, it’s time to get the cleaner out.

Step #2: Use a Cleaning Concoction

Apply the cleaning solution to the inner walls of the sink with a brush or a sprayer. Take a break once you’ve finished covering the entire sink bowl.

You may want to lie quietly for a time and allow the cleaner to do its work, depending on your routine and how discolored or dirty your sink is. 

No matter how long your break is, make sure the rest of your family is aware of keeping them away from the washbasin for the meanwhile. By the end, y you’ll all be delighted you took the initiative.

When your break is finished, put on some safe, water-resistant mittens and get back to work!

Step #3: Scrub, Rub, Scrub

Begin washing your sink using the same rag or fabric that you used to wipe it off! The cleanser will aid in the removal of any filth or grime from the sink’s surface. 

Darker, denser stains may require a little more effort to remove. Don’t be concerned. Because, even if they don’t seem to go away after the first wash, they’ll start to fade away after a few days.

Turn on the faucet and start rinsing for the last time. Rub as hard as you could (if pale stains are still there), don’t worry, your hard work will pay off.

Step #4: Wipe to Decontaminate

Use clean, cold wipes to clean your sponge or rag. After that, using a cleaning solution, remove the spots.

If you are trying to clean your basin with bleach, you’d need a lot of warm water. Be cautious with the bleach!

If you don’t, you can end up with bleach residue on your surfaces. This is especially harmful when dogs or young kids are involved.

After the sink has been thoroughly rinsed, disinfect it. Spraying disinfectant spray on the surfaces is the simplest way to do this. 

How to Cleanse a Kitchen Sink

Well, there isn’t much difference between cleaning a kitchen sink and a washbasin. However, keeping health in concern, you should sterilize the kitchen sink from to time. The dishes (even the cleaned ones) may carry the contaminants if the sterilization is not carried out correctly.

Step #1: Rinse and Wipe

Put on your gloves and get ready to wipe off your sink once you’ve gathered your supplies. Don’t forget about your sink’s faucet, sidewalls, and underside.

Don’t forget to wash your cleaning tool after one session. It is essential to clean the sponge or rag properly in order to keep everything tidy. If the sponge has got damaged, we suggest using a new one rather than recycling the last one.

Your surfaces will be ready for the cleaning solution after a quick rinse with warm or tepid water.

Step #2: Use a Cleaner

On your sink, spray or spread your favorite cleaning solution. Because kitchen sinks are typically more extensive and more sophisticated than bathroom sinks, make sure to cover every visible surface.

Don’t forget about your faucets, handles, and drains! They might not be discolored, but they’re sure to be strewn with bacteria.

If you’re dealing with set-in stains, you may want to take a little rest before cleaning. The most straightforward technique to deal with kitchen sink filth is to get started right away!

Step #3: Scrub to Clean

Use a non-abrasive sponge or rag, as well as a pair of protective gloves. Then let out your rage on the filth and grit! Scrub all surfaces with a stiff brush.

It’s possible that you’ll want to go over all surfaces twice. Spending additional time on more hardened, set-in dirt or stains is also a good idea. But don’t get discouraged if you encounter opposition.

Multiple cleanings will reduce the amount of dirt and stains on the inner walls of the sink. However, it can take some time and a bit of labor. 

Step #4: Use Warm Water to Wash the Sink

Rinse the cleaning solution off all sink surfaces with your cleaning instrument (or your sink sprayer). While you’re out and about, warm water will assist in disinfecting!

Step #5: Sanitize Everything

When it comes to disinfecting your kitchen sink, the most critical step is disinfecting it once it’s clean. Bacteria, mold, and mildew will not take hold and leave stains if this is done.

Disinfectant sprays are ideal, although you can also use a bleach solution, vinegar, or boiling water.

The Most Effective Sink Cleaners

Whether you prefer a natural approach or want to use harsh chemicals, there’s a sink cleaning that’s right for you!

1. Vinegar, Baking Soda, and Salt

Baking soda, or sodium bicarbonate, is a multifunctional ingredient that has the potential to improve your life. It can assist with stomach problems, carpet odors, and even drain clogging.

When baking soda, salt, and vinegar are mixed, you obtain a super-reactive and powerful cleaning solution!

Baking Soda

Baking soda is a type of salt with a slight abrasive property. As a result, adding table salt or sea salt improves its abrasion properties. This permits the mixture to scrape dirt, mold, and mildew away from the tougher substance underlying it without harming it!


Vinegar is highly acidic, and when combined with baking soda, it can cause a chemical reaction. Every primary school volcano maker is quite aware of this introductory chemistry. However, you may incorporate it into your cleaning routine to make cleaning a breeze.

This concoction can remove hard water stains by coating the sink with a baking soda, salt, and vinegar solution for thirty minutes to an hour.

When you take out the drain plug, the frothy substance will unclog the sink pipes as it descends! While it is the least hazardous option, it is not the most effective one (yet it is fun to watch).

2. Juice of a Lemon

Cleaning products made from natural acids are lovely. Citrus juice, such as lime, lemon, and grapefruit juice, is highly acidic. While this feature makes them unsuitable for composting, it makes them ideal for home cleaning.

You can buy lemon juice in a bottle at your local grocery shop or squeeze some yourself. Fill a clear, sanitized spray bottle halfway with lemon juice. Fill the container with clean water or white vinegar.

You now have an all-purpose cleanser that smells amazing! To use, spray it over any oily, dirty surfaces and leave for a few minutes. Wipe the surfaces with a clean, wet cloth after about 10 minutes.

3. Bleach

Bleach, according to popular belief, dissipates over time and leaves no toxic trace. This is not the case. If you use bleach to remove stubborn stains from your sinks, dilute it with water first.

Also, avoid coming into touch with the bleach solution with your eyes, mouth, or skin. You’ll also need to use more water to make sure your surface is tidy. As a result, cleaning your home with bleach might be time-consuming, damaging to your health, and increasing water costs.


Acids, chemicals, and other harsh cleaning agents and practices can damage fiberglass. If your sink has unbeatable stains, then this can be a significant pain!

Fiberglass can become dull, dirty, and stained with time, just like fiberglass shower floors. This is due to the fact that it is made of a composite material that is easily scratched.

The more scratches on your sink, the simpler it is for stains to penetrate and become stuck in the tiny crevices. When washing a fiberglass sink, you’ll need to take extra precautions. All you need to do is trust the process and let the cleaning solution stay for a while.
