Hillmark Scalex Heavy Duty Home Descaler 375g Questions & Answers

I wouldn’t. It is extremely strong and toxic and I wouldn’t take the risk using it on any food or drink utensils.

Hi Baxter, We would not recommend using the Hillmark Scalex Heavy Duty in the coffee machines. For this application we would recommend using out Hillmark Expresso Kleen. external link  Kind Regards, Selleys Help & Advice Team

I have used this by accident will the kettle be okay to use

Hi Julie, Hillmark Scalex Heavy Duty can be used where septic systems are in use, but we would suggest using only half the recommended dosage, and to rinse very well after use. We would also recommend spacing out the descaling chores over a few days or more. Selleys Help & Advice Team

Hi Rebecca, Unfortunately we could not guarantee how successful Scalex Heavy Duty would be on this type of surface. If the cistern cover it made of plastic, Scalex will not work as the yellowing is in the plastic itself. If it is a ceramic cover, we would suggest testing in an inconspicuous spot before to see if it will be suitable to use. Selleys Help & Advice Team

Thank you

Hi Marie, We would suggest contacting the manufacture to see if this product is suitable to use with your system. We have not tested on this and could not guarantee how successful this would be. Selleys Help & Advice Team

Can’t be used on glass not safe. For glass I use 1 drop of almond oil. 1 drop is enough for both sides on a towel or old panty hose and rub in to glass.

I've used it on shower glass for years with great results. I just spray on, let sit for a minute, them wipe it off with a sponge. Removes all the calcium and build up water stains. Just be mindful that the smell can be overpowering in the confined space of a shower.

No dilution. I gave two -three generous squirts straight from bottle, brushed and let stand in bowl overnight.... the miracle was in the morning!!!

Not at all. I just put the product in, brushed n left overnight and stains were gone in the morning. It was amazing as I had tried countless other products, blessés etc to no avail. I highly recommend it and the product goes a long way!

Thank you…I’ll give it a go.

I haven’t tried as other products can easily clean but can certainly swear by it for removing deep toilet stains that NO OTHER PRODUCT tried could remove!!!

I had a shower just the same when we moved in. Did all the things you have. However I hadn’t heard of this at that stage...so I don’t know if it would work. I know the scalex is an amazing product, but the product needs to be able to sit on the build up to work.. this is hard on a vertical surface....give it a shot...I ended up replacing the glass and the company said that the glass had “glass cancer” which meant the lime had eaten away the top layer and nothing would clean it back to new....good luck!

Thanks for the info. Tried the scalex and it is going to require some patience. Made a big difference compared to the other remedies I’ve tried. Just not what I’m happy with. Might have to replace the glass after all.

If you enlarge the pic of the container of Scalex, there is a pic of a front loader washing machine, so obviously considered safe to use on them. However Hillmark also make specific descaler/cleaner for washing machines that comes in a box of 3 x 75gm sachets. They are sold at Mitre 10 stores, but not sure about other stockists.

Yes absolutely!!! I have used it in mine for over 10 years... it was the recommended by the washing machine shop and it is the best cleaner I have ever used and also the most economical. One bottle will last about 3 months and do my dishwasher every month and washing machine. Much cheaper than the package version. But that does work just as well and has a nice smell too...Brilliant stuff!

Hi Michelle I don't think it's a good idea. Unless you put in your toilet, let it sit over night and remove water by hand without flushing. And repeat again next night. Sorry I wish I could come up with a better answer.

It’s best to do this overnight...Bucket out the water in your toilet as much as possible. Dissolve about half a bottle of Scalex in hot water...don’t breathe in the fumes... wait till the water cools down a little then pour into toilet.. leave overnight...scrub in the morning. Then flush. If the build up is very thick or very old...it will probably need another treatment that night and if it’s really bad maybe a third night...seems like a hassle but let me tell you it’s way cheaper and less hassle than getting a new toilet put in!!

Sorry I have no idea I just seen a article on how well it can clean toilets, so I brought some from eBay. And it's the best stuff I have ever used, I had lime in toilet for 10 years 2 goes over night and it was gone.

Not 100% sure, maybe do a Google search to see if it's safe? I only have a regular loo system and it was safe on that.

Hi Ivy sorry for late reply yes it's 100% safe for septic system. Hillmark Scalex gets tough on lime, calcium and rust. Lime scale & calcium build-up decreases the efficiency of hot-water appliances, which increases running costs & shortens the appliance’s life. This is particularly severe in hard water areas, which is where Scalex does its best work. Its super concentrated formula makes Scalex the fastest & most effective descaler on the market Idea for use: Glass, plastic, metal & stainless steel ,Internal pipes, septic systems & valves.

Not too sure to be honest but if you use Facebook just search for cleaning groups in the search bar. Some are called things like cleaning tips and tricks or cleaning hacks etc. That's where I first learnt about this product, before that I had never heard of it before! Once you've been accepted into a cleaning group, you can search within that group about anything anyone has said about scalex simply by typing scalex in the search bar (make sure you are on the group page search bar and not the usual Facebook search bar)
