Great product

8 months ago
This is easy to mix, strong fumes definitely need ventilation. It’s great and works well, will definitely be recommending it and keep using it.

Good remover

I have been really impressed with this product and how it works. It is easy to assemble and works quickly to remove stains. It does have a loud odor but I can get past that.

I was honestly surprised by how well this worked. I used it on a stubborn stain that I thought was permanent, and it lifted it almost immediately. The instructions were easy to follow, and results were great!!

Just okay.

I do think this product works very well. I am personally not a fan of having to mix the product myself. Leaves room for error and I don’t think it works well enough to make it worth it.

Powerful Outdoor Cleaner

9 months ago
Wow, this stuff is poweful! Lots of scary warnings and safety tips on the bottle and packaging. Would only recommend for outdoor use and with safety goggles, but it works really well on tough mildew stains. Strong bleach smell, but it does the job!

Did Not Enjoy Noxious Fumes

9 months ago
Does it work, yes. But, it comes with too many health warnings for me to be comfortable with. I used it on my soap scum and mineral water strained shower walls. I let it sit 10 minutes and them scrubbed and rinsed. Even with the window open and exhaust fan on, you could smell it at the entire opposite end of my house. This stuff contains sulphuric acid- the same thing in drain cleaners. I think it could be used outside on super tough cleaning projects, and at a professional level… but for normal household use it’s a big NO from me. I’m sticking to baking soda and vinegar!

Alien power multi purpose stain remover worked great for me. Very easy to use. Very easy to mix since its a powder that you add water to and it comes with a bottle. I used it to git rid of mold, it worked great.

Alien Power Multi-Purpose Stain Remover looks like a very effective solution for tough outdoor and household stains. The formula is designed to tackle mold, mildew, water marks, and general buildup, which makes it especially useful for outdoor surfaces. I like that it’s positioned as a multi-surface cleaner. It seems particularly well-suited for garden and patio furniture, outdoor tiles, grout, siding, and other areas that are constantly exposed to dirt and weather. This is exactly the type of product that can help refresh outdoor spaces and bring surfaces back to a cleaner, well-maintained look. Another strong point is that it can be used both indoors and outdoors, which makes it practical to keep on hand for different cleaning needs. Overall, Alien Power appears to be a solid choice for anyone looking for a powerful stain remover for exterior cleaning and hard-to-clean areas.

Not a fan of this!!!

9 months ago
I was eager to try this because I love any cleaning product that is multipurpose. However I used this and it smelled like straight up bleach!!! I even went as far as diluting it to clean and it ended up warping my shower curtain (which it said it could be used on!)

Great for outdoor stone stains

9 months ago
Used the stain removed outside to clean white stains on the stone and it worked well. After one round, the area already looked much cleaner. I do think I need to do one more round to really get the stone to sparkle, but I’m really happy with the first round results. Super easy to use, no weird or strong smell and has been great for outdoor use. I have not used inside as I’ve been putting it to work outside. Packaging was simple, no issues!

Effective cleaning product

10 months ago
I like that the bottle is reusable and comes with refillable packets. It was really easy to pour the powder in with warm water and it was ready to be used in minutes. I tried it as a tester on my dishwasher edges and it cleaned all my grime off without much scrubbing. I’m excited to try it next on my bathroom grout.

Great product? YES

This spray is a great stain remover and all around multipurpose cleaner. It removes grease and I also found that after some time my surfaces don’t collect as much dust over time. The smell is mild and doesn’t really take over the room which I like. The nozzle is simple and sprays evenly.

Works Well

10 months ago
This all purpose cleaner does exactly what it says it will. I’ve used it on my countertops and I’ve used it in my bathroom and it has worked well in both scenarios. The smell isn’t too overpowering which is great and the spray bottle is functional.

Amazingly effective

10 months ago
So, first and foremost, USE IN A WELL VENTILATED AREA. The fumes from this are strong, but so are the results. I was skeptical I've tried so many things to get rid of the ick from my sons bathtub. This Alien Power has legitimately been the only thing that worked. You can see how white the caulking/grout is now. The directions were simple and I like that it came in powder form because this is not the kind of chemical you want leaking. Definitely store away from kids and pets, this stuff is powerful and will harm them if ingested or if it gets on sensitive skin. All that said, I will absolutely use this agin and again as it 100000% works.

Out-of-this-world results! The only stain remover

10 months ago
The first time I used it was on the stubborn black mold in my shower grout. I simply sprayed the gel onto the area, left it while I ran errands, and came back hours later to a sparkling, mold-free tub. No scrubbing required! It has saved my favorite shirts and even an heirloom quilt from berry juice stains that I thought were permanent.

Great product would recommend

This product is pretty great. I had some red ish stains on my shower curtain and in my shower. Sprayed it directly on the stains and with minimal scrubbing it was all gone! Great product would recommend.

Crazy powerful stain remover!

Crazy powerful stain remover! Be careful because a little goes a long way! Also be sure to test for colorfastness (as instructed) because this will bleach some materials.

Product don’t work. Tried all stains that it stated in the label that it removes and it didn’t do what it was supposed to do. Don’t like the fact it isn’t a kid or pet safe product. Would not buy this my self at all.

Alien Super Power

This cleaner definitely works its magic and helped me lift this pesky mold and dirt residue from my terrazzo floors. The only downside is the smell is quite strong, just like bleach, but I guess that’s to be expected. It’s definitely a product I would purchase again.

Works great!

This stuff cleaned extremely well. You do need to use in a well ventilated area. It’s a very strong smelling cleaner. I love that the sprayer has two different settings, jet and mist. The trigger is easy to do. It was easy to pour the packet into the bottle, the bottle is actually heavy duty and it dried fairly quickly, not leaving behind a residue after wiping clean.

This works well, it did the job decently but I wish it worked better on mold stains, over all for regular cleaning I would recommend. It comes with the powder and spray bottle separately to mix.

Alien Power Multi-Purpose Stain Remover

10 months ago
This stuff seriously lives up to the name — it’s out of this world. I grabbed Alien Power to tackle some tough stains and was honestly shocked at how well it worked. From mystery kid messes to set-in stains on fabric and carpets, it sprayed on, sat for a bit, and wiped clean with almost no effort. I love how easy it is to use — just spray and let it do its thing. No harsh scrubbing, no strong overpowering smell, and it actually works the first time. As a busy household, I need products that save time and frustration, and this one delivers. If you’ve got kids, pets, or just everyday life happening, this is a must-have in your cleaning stash. I’ll definitely be keeping this on hand and repurchasing.

Power Packed Cleaning Performance! Alien Power Roc

Loved it! The package includes a spray bottle , packets and of course instructions on how to use . Easy to mix and use. I used it on my shower curtain to spruce it up and clean soap residue . It worked without damaging or leaving spotting . It is concentrated and has to be diluted . I used it in an well ventilated space . Worked like a charm! Very good cleaner . . Glad there’s a product for tough stains . The directions tell us what it’s used for it is multi purpose but adhere to the warnings on label ! Definitely buying this for cleaning !
