Frequently Asked Questions



Q. Does the product really work?

A. The reason we put this in our FAQ section is because plenty of people call us with this one single question. Fair enough question also, as you want to know what you are buying works as promised. Yes… the product absolutely works as demonstrated in the video. We now have over 30,000 residential & commercial customers using the product in NZ.

Q. How much do I need to buy?

A. The coverage depends on how absorbent your curtains are; how big they are; how much mould you’ve got; how many applications you need to do if it’s very stubborn mould – so it is impossible to say what coverage you’ll get. But generally 4L is suitable for a houselot of curtains with mild to moderate mould.

It’s important that you spray the product liberally because you won’t get best results if you are trying to make it stretch the distance and apply only sparingly. If you don’t have enough, you can always buy some more.

As a rough guide:

1L Container – 1-2 curtains with moderate mould.

2L Container – 1-4 curtains with moderate mould.

4L Container – 1-8 curtains with moderate mould.

Q: Any tips about how to apply the product?
A: There are a few ways, depending on the configuration of your curtains. Follow label instructions on bottle before applying.

  1. Leave the curtain hanging, then pull it out the door or window. This will give you easy access to the mould on the rear lining. Rest the curtain over plastic garden chairs if it’s a slider door… or if it’s a window then simply hang them out the window frame.
  2. The best way is to take them down and hang them over the clothesline. Do this on a sunny day in the morning, and they should be dry (or near enough), to rehang by the afternoon.
  3. If the curtains are small, you can hold the corner of the curtain out, and spray on with the other hand. All surrounding surfaces need to be covered incase the liquid drips onto a non-colourfast surface.
  4. If you are treating the lining only (98% of customers), and don’t want the liquid to go through to the coloured side… try unclipping the small clips down the side, and fold the front of the curtain back up on itself so only the lining is left dangling (Use pegs to hold the curtain up and out of your way). This gives easy access to treat the lining.
  5. If your curtain is attached/stitched to the lining, then it’s normally open across the bottom for ventilation purposes. If this is the case, you can slip some cardboard up between the curtain and lining to prevent the liquid transferring across.

Please note: The application directions are on the bottle.

Q: Is Curtain Magic suitable for all thermal curtains?

A: Yes, as long as they are colourfast and you haven’t treated them with other solutions first. Always do a colourfastness test, even on the white thermal backing – because sometimes the manufacturers of the lining could have used an underlying dye that can come through the white colour upon application of our solution and discolour the lining. Also, the solution can penetrate the backing and go through to the front part of the thermal curtain – so you need to do a colourfastness test both on the white backing and on the coloured side to make sure that there will not be any discolouration on either side before applying the solution liberally.

Q: I’ve used other solutions on my curtains, is it safe to use the Curtain Magic?

A: We generally don’t recommend using our solution over previously treated curtains because a residue could have been left from the previous treatments and that can react with our solution. You need to make sure that your curtains are free of previous solutions and do a colourfastness check first to make sure that there will not be any unwanted reactions.

Q: Can your curtain mould remover be used to remove mold from the front of curtains / coloured part of curtains / both sides of curtains?

A: Yes. But you need to make sure your curtains are colourfast before applying the product liberally. How to do a colourfast test.

Q. If the first application does not clear all the old stubborn mould should one re apply, and how long after the first application and should another application be needed?

A. The level of stubborness of mould, and how much product you will need depends on:

  • The age of the mould – the longer it has been on your curtains, the more applications are needed to get rid of it;
  • The curtain / blind fabric – the less pourous and more synthetic the material, the easier to remove;
  • Whether the mould has been unsuccessfully treated with other products prior to using our solution – any unsuccessful attempts to remove the mould, makes the mould more stubborn and difficult to remove, than untreated mould;
  • The way you apply the product – spraying the product in a windy environment, or in cold conditions below 15 degrees, or from a distance further than 2-5cm away from the treated area, or not liberal enough i.e. not saturating the area so it drips, or on a hot day when the solution evaporates quickly off the warm curtain surface – can all affect the effectiveness of our product and require more applications than ‘usual’.

Once you see the mould starting to change colour from black to brown, you know the solution is working – so all that is needed is for you to spray it as many times as needed to get rid of your mould. This may mean that you need to spray only once, as is the case in our video where our mould is only one year old and is on a rubbery, thermal back surface or you may need several applications.

You just need to spray it liberally from a close range, let it sit for 2-3 minutes and spray again. Repeat until the mould is gone. There is no need to wait for the curtain to dry before re-applying it – it’s best to spray it while it’s still wet and leaving no longer than a few minutes between applications.

We’ve had people that have been able to clean two house lot of curtains with one 4L container. And we’ve had people who have needed 2 lots of 4L containers to get rid of the mould in their house. So there is no hard and fast rule on how many applications are ‘normal’ to get rid of the mould, as it all depends on your mould and your curtains and your application.

Q: Should I protect the carpet and surrounding furnishings when using the curtain mould remover?

A. Yes. Cover any carpet, surrounding furnishings and anything else that is unintended for our product with a plastic sheet to prevent it from any stray spray or drips. In some cases, carpet and furnishings are not colourfast.

Q: How do I apply the product?

A. The solution comes ready to go, no diluting. Simply tip the curtain mould cleaner into a regular household bottle and select the spray setting on the nozzle (Don’t use the fine mist setting). Apply liberally. Note: Make sure you run water through the spray nozzle prior to using the curtain magic to ensure other chemicals are cleaned out the nozzle.

Q: Does this product remove mould from netting curtains?

A: Yes, our curtain mould remover gets rid of mold on nets. You just need to make sure they are either white nets or colourfast netting curtains before applying the product liberally.

Q: Can your product be used to remove mould from children’s soft / stuffed toys, prams or strollers?
A: We don’t recommend using our mould remover around children or on their toys, prams, bedding, cots etc.

Q: Can your curtain mould remover be used on carpet, mattresses, cushions, duvets or couches?
A: We don’t recommend using our product on any spongy materials as the solution will get absorbed into the spongy material before it has a chance to remove the mould on the surface. Also, you risk having some discolouration if those materials are not colourfast.

Q. My curtains/blinds have metallic threads/patterns or metal rods/embelishments on them, is Curtain Magic safe to use on those materials?

A. No. You cannot use Curtain Magic on fabrics that have unpainted/unsealed metal threads/parts as our solution will discolour/oxidise those.

Q: What’s the shelf life of your products?
A: If you keep the products airtight and store them in a dark place and at a cool temperature – they could last you up to 6 months.

Q: Does your product need to be diluted?
A: No. Our mould removers do not need to be diluted as they are ready to use.

Q: What area does 4L cover?
A: Generally, a 4L container is sufficient to clean the curtains in an average sized house. However, it’s hard to say what area can be covered because the coverage depends on how much mould you’ve got, how many curtains / walls / ceilings etc you’ve got to clean, how porous your curtains are etc.

Thermal or Colourfast Curtains – Please do a colour test on a small, hidden area of your curtains before applying it liberally. Once satisfied with the sample test, you can go ahead and spray the mould on the curtains, making sure you’ve covered any carpet or upholstery to protect them from any stray spray. If your curtains have unattached white lining behind the coloured curtain, put a piece of cardboard between the coloured layer of the curtains and the white lining and spray the white lining only. Pay attention not to let the wet lining come into contact with the coloured fabric. It’s best that you wear a mask so you don’t breathe in the product.

Ceilings & Walls: The most effective method is to spray the product on, working steadily, covering all areas well. After all traces of mould have disappeared clean the mop with fresh water and with lightly damp sponge, wipe off any excess moisture.

Wallpaper: We recommend spraying wallpaper for best results. Work from the bottom up to prevent streaking. Streaking occurs when spraying begins at the top and excess product runs down the walls leaving clean lines.
To eliminate streaking, spray the entire area from the bottom and work up. Once the area has been cleaned and all traces of mould have disappeared, wipe area well with a clean dry cloth to remove excess water.
Wallpaper should be tested for colour fastness first.

Bathrooms: Because shower curtains are waterproof, both sides must be sprayed to eliminate mould. Work with a dry curtain, spray well to cover the mould. We recommend spraying the curtain late at night and the next morning the curtain will be clean.
