How to Choose Washing Machine Cleaner (洗衣槽清潔劑) in Taiwan: No-Soak Oxygen Powder vs Chlorine Liquid, and the Cost per Wash
You cannot see the dirt on the inside of the washing machine drum, but over time it brings a smell, black sticky residue, and even marks that get back onto your clothes. Washing machine cleaners on the market fall roughly into two groups, oxygen powder and liquid chlorine, and the way they remove dirt, whether you have to soak, the pH of the ingredients, and the cautions for use are all different. This guide explains the 3 types, 4 things to check, and how to work out the cost of each clean, so you can decide which one to buy.
First, Understand the 3 Common Types of Washing Machine Cleaner
| Type | Features | Who it is for |
|---|---|---|
| Traditional soak-type powder | Mostly an oxygen formula such as sodium percarbonate. You usually fill the drum with water to dissolve it and soak for several hours so the dirt softens before draining. It takes longer, but the ingredients are relatively mild | People who are not in a hurry and like a big clean at the weekend |
| No-soak oxygen powder | Also an oxygen formula, but with an added activator so the powder dissolves fast, and it is advertised as taking about 45 minutes in total and not being much affected by water temperature | People who want to save time, or who need to clean in cold water in winter |
| Liquid chlorine cleaner | Mainly hypochlorite. It is liquid, so it needs no dissolving first, and stresses removing dirt and smell in a short time. It is a fairly strongly alkaline formula, so you need to take special care with safety | People who want to deal with it quickly, or whose drum has an obvious smell |
No single type is "the best". It mainly depends on how much time you are willing to spend, how you feel about the pH of the ingredients, and your washing machine model. A liquid chlorine formula is more strongly alkaline, so follow the pack when using it, keep the room ventilated, and never mix it with acidic cleaners.
4 Things to Check When Choosing Washing Machine Cleaner
| What to check | What to look at |
|---|---|
| Ingredients and pH | Oxygen powder (sodium percarbonate) is weakly alkaline, for example a stated pH of 9.5. A liquid chlorine type usually contains hypochlorite and sodium hydroxide, and its pH can be as high as 12 or more, which is more strongly alkaline, so read the instructions carefully before it touches skin or clothes |
| Whether you need to soak, and how long it takes | A soak type often takes several hours, while a no-soak type advertises about 45 minutes. The time on a shop page is the maker's test figure, and the real time differs with the machine and how dirty it is |
| Which machines it suits | Check whether the pack says it suits top-loading and front-loading machines. The water level and drain method differ by machine, so do not assume it works for every one, and compare it with your washing machine manual before ordering |
| Antibacterial and test labels | Look at whether it states a third-party test (such as SGS) and the test bacteria. Such data are usually laboratory results under specific conditions, so you can treat them as a reference, but they do not guarantee the same effect in every washing machine |
How to Work Out the Cost per Clean So the Size Does Not Fool You
Do not look only at "how much for one box". Work out "total price ÷ number of cleans" for the cost per clean. Powder is often sold as 2 sachets or 4 sachets, and one sachet is usually one clean. For a liquid bottle, check the suggested amount on the pack, and then work out how many cleans a bottle gives. Suppose one powder box of 2 sachets costs $140, which is about $70 per clean. Another liquid bottle costs $120 and the suggestion is half a bottle each time, which is about $60 per clean. They look about the same, but you should also take into account the time, how strongly alkaline it is, and safety, and not compare only the unit price. How often to clean the drum depends on how much you use the machine and your water, and a common suggestion is about once every 1 to 3 months, but this is general upkeep advice, and you should go by your washing machine manual.
Choosing by Situation
- You are busy and want to save time — Look first at a no-soak type, because the whole process is short and suits a free evening or weekend slot.
- It is winter, the water is cold, and you worry soaking will not work well — Choose an oxygen formula that says it is not affected by water temperature, and follow the water temperature range on the pack.
- The drum already has an obvious smell or black residue — You can consider a liquid chlorine formula to deal with it quickly, but wear gloves, keep the room ventilated, and never mix it with acidic cleaners.
- You have children or pets, or you care about leftover residue — After use, rinse once more as the instructions say, and store the cleaner where children cannot reach it, especially a strongly alkaline liquid formula.

Yi Di Jing (一滴淨) No-Soak Time-Saving Washing Machine Cleaner (200g / 2 sachets) / Liquid Washing Machine Cleaner 520g (Shopee Mall direct)
Shopee Mall direct store listing information (shown on September 30, 2026; prices and promotions may change): 2 options, with a price range of $119 to $139 (original $139 to $175, about 14% off), 2,000+ sold, and 955 reviews with a 5-star rating shown. The buyer tags are mostly fast shipping (52), good cleaning results (29), and intact packaging (18). Installments at 0% interest from $40 per period for 3 periods are shown, delivery as early as the next day, shipping from $0, and Shopee's official direct protection. Option one is the "no-soak time-saving washing machine cleaner (200g / 2 sachets)", a powder that advertises about 45 minutes in total and not being affected by water temperature. The listed main ingredients are an oxygen decomposer, sodium percarbonate (an active-oxygen descaling salt), a natural builder, and a T activator, with a stated pH of 9.5 ± 1, and it states antibacterial 99.9% by SGS testing (test bacteria: E. coli and Staphylococcus aureus). The time needed differs a little by brand and machine. Option two is the "liquid washing machine cleaner 520g", with listed ingredients of hypochlorite, sodium hydroxide, surfactant, and stabilizer, and a stated pH of 12.5 ± 1. It suits top-loading and front-loading machines, has a 3-year shelf life (unopened only), and must be sealed and kept in a cool place out of the sun after use. The listing also says the liquid formula works mainly by dissolving dirt and not by peeling it off, so it works differently from the powder, and seeing few seaweed-like pieces of debris is normal. Before you buy: the liquid formula is fairly strongly alkaline, so read the pack instructions carefully before use. For hygiene reasons the listing says that once opened it cannot be returned or exchanged unless the product itself is faulty. The main image once showed some options as "sold out", so check the stock and latest price of the option you choose before ordering. Please go by the listing page for these labels and specifications. This site does not give product safety advice.
Quick Checklist Before You Buy
- Want to save time? → Choose a no-soak type, and check the total time stated
- Is your machine top-loading or front-loading? → Check that the pack and your manual both say it suits
- Care about how mild it is? → Compare the pH and main ingredient, and for a strongly alkaline chlorine liquid wear gloves and keep the room ventilated
- Want to know if it is a good deal? → Work out "total price ÷ number of cleans", and do not look only at the total price
- Before you order → check the stock of the option, and note the label that says no returns once opened
Frequently Asked Questions
- Can washing machine cleaner be used together with other cleaners?
- We do not recommend it. Chlorine cleaners especially must not be mixed with acidic cleaners (such as some toilet cleaners and descalers), which can produce harmful gas, and do not mix a powder and a liquid yourself either. Use only one at a time as the pack says, and rinse well when you finish.
- How often should I clean the washing machine drum?
- A common upkeep suggestion is once every 1 to 3 months, but it really depends on how often you wash, your water, whether you often wash underwear or pet items, and the advice in your washing machine manual. If you notice a smell, black flakes, or sticky residue on clothes, you can clean it sooner.
- Will any chemicals remain on my clothes after using washing machine cleaner?
- After you finish the cleaning as the pack says and drain and rinse, it generally does not affect later washes, but we suggest running one more empty rinse cycle with clean water afterward and leaving the drum open to air dry. If you have sensitive skin or baby clothes at home, rinsing one more time is even better.
