I bought PrimeDrum Washing Machine Deep Clean Tablets because I wanted something that would properly clean the inside of my washing machine, especially around the rubber seal where dirt and black marks can build up. The advertising made the product sound impressive. It claimed to use three enzymes to break down pet hair residue, body oils and other dirt, while also getting rid of the musty smell that can develop inside a washing machine.
What I received was not quite what the advert led me to expect. The video talked about enzymes such as amylase and lipase, along with another enzyme, but when I checked the ingredients on the tablets I received, I could not find any enzymes listed. There was also a problem with the quantity. The seller advertised a 50% offer, saying I would get 24 tablets for the price of 12, but only 12 tablets arrived.
I have used five tablets so far, following the instructions, and I cannot say the results have been impressive. The smell has improved somewhat, but the rubber seal still had black marks after several cleaning attempts, and I was left wiping away dirt that the tablets were supposed to help remove. So, while PrimeDrum has helped with some of the smell, I am not convinced it does everything the advertising promises.
What Is PrimeDrum Washing Machine Deep Clean?

PrimeDrum is a washing machine cleaning tablet designed to clean the inside of your machine and help remove the dirt and residue that build up over time. The product is marketed towards people who struggle with musty smells, pet hair residue, body oils and grime around areas that are not always easy to clean during an ordinary wash.
The tablets are effervescent, meaning they dissolve and release cleaning ingredients when placed in water. According to the product description, they are supposed to do more than simply make the washing machine smell fresh. PrimeDrum claims to break down dirt, remove odours and clean areas where residue can collect.
The advertising also puts a lot of attention on its supposed enzyme formula. It mentions protease, lipase and alpha-amylase, which are enzymes used for breaking down different types of dirt. Protease works on protein-based residue, lipase targets oils and fats, while alpha-amylase breaks down starches. These are useful ingredients in cleaning products, so I can understand why the seller makes such a big deal about them.
PrimeDrum Ingredients: Where Are the Enzymes?
This is one of the biggest reasons I am unhappy with the product. The advertising video claims that PrimeDrum contains amylase, lipase and another enzyme, but when my tablets arrived and I checked the ingredients, there were no enzymes listed.
The product page also describes other cleaning ingredients, including sodium percarbonate, citric acid and sodium carbonate. Sodium percarbonate is an oxygen-based cleaning ingredient, citric acid can help with mineral deposits, and sodium carbonate helps with cleaning by making the solution more alkaline.
Those ingredients may have cleaning uses, but my issue is that the enzyme claims were a major part of the advertising. If a product is being sold on the strength of a triple-enzyme formula, I expect to see those enzymes clearly listed on the product I receive. I do not think it is fair to make a big selling point out of ingredients that buyers cannot find on the supplied product’s ingredient list.
I would have been much happier if the seller had clearly explained the formula and made sure the product information matched what was actually delivered.
My PrimeDrum Experience: Did It Clean My Washing Machine?
I followed the instructions and used the tablets in an empty washing machine drum, rather than putting them in the detergent dispenser. My main concern was the rubber seals, which still had black marks and a musty smell. I wanted to see whether PrimeDrum could deal with the dirt that ordinary washing had not removed.
I started with one tablet, but after that first clean, the rubber seals were still dirty and there was still a slightly musty smell. I was not impressed, so I waited a week and tried again, this time using two tablets.
There was a little improvement, but it still did not clean the machine properly. The rubber was still showing black marks, so I wiped it with a cloth to see how much dirt was coming away. The microfibre cloth was left very dirty, and although the rubber looked a little better, it was nowhere near as clean as I expected after using the product.
I then repeated the whole process immediately with another two tablets. Again, there was a small improvement, but nothing that made me feel the machine had been properly cleaned. When I went to do another wash the following morning, there was still a slight musty smell.
By that point, I had used five tablets, and I was beginning to question what I had actually paid for. The product is advertised as being able to clean hard-to-reach dirt, thoroughly clean every corner and remove odours. Based on what I have seen so far, I would not say it has delivered those results.
Does PrimeDrum Remove Washing Machine Odours?
This is the one area where I noticed some improvement. After using a tablet, the smell in the washing machine did seem to go away, which was one of the things I wanted it to do.
However, the improvement has not been enough for me to say the problem is completely solved. After several cleaning attempts, I still noticed a slight musty smell before doing another wash. I also do not know how long the fresher smell will last, so I will have to see what happens with continued use.
Getting rid of an unpleasant smell is useful, but I also wanted the tablets to clean the rubber seals and remove the dirt that was already there. I do not want a washing machine cleaner that only makes the machine smell better while leaving visible grime behind.
PrimeDrum 50% Off Offer: I Ordered 24 Tablets but Received 12
The other problem I had was with the seller’s offer. The product was advertised at 50% off, with the promotion saying I would receive 24 tablets for the price of 12. That was part of the reason I decided to order because it made the purchase seem like better value.
Unfortunately, only 12 tablets arrived.
I was expecting twice that number based on the offer I saw, so this was disappointing before I had even tested the product. When a seller advertises a specific quantity, I expect that quantity to arrive. It should not be left to the customer to work out why the order contains fewer tablets than promised.
This also makes the product less attractive when you consider how many tablets I have already used without getting the cleaning results I wanted. Five tablets have gone, and I still have a washing machine with black marks around the rubber seals and a slight musty smell.
Is PrimeDrum Washing Machine Cleaner Worth Buying?
I am not completely satisfied with PrimeDrum. The advertising made it sound like a powerful washing machine cleaner with a triple-enzyme formula that could tackle the dirt and smells ordinary washing leaves behind. But the ingredients on the tablets I received did not list the enzymes promoted in the video, and the cleaning results have been disappointing.
I have used five tablets, including repeated cleaning attempts with two tablets at a time, and the rubber seals are still showing black marks. There has been some improvement in the smell, but it has not lasted well enough for me to say the product has solved the problem. I also received only 12 tablets despite ordering under an offer that promised 24.
I will probably use the remaining tablets because I have already spent the money, but I honestly do not have high hopes that they will suddenly start doing what the advertising claims.
I would not recommend PrimeDrum based on my experience so far. The missing tablets, the difference between the advertised enzyme claims and the ingredients listed on the product, and the limited cleaning results have left me disappointed. It may help reduce some washing machine odours, but I have not seen it properly clean the rubber seals or remove the dirt that was bothering me in the first place. I expected much more from a product marketed as a deep cleaner.
