HLS Supplies5L AT-55 Awning & Tent Cleaner - Perfect for Parasol, Gazebo and Outdoor Fabric

Does a excellent job of cleaning my tentI personally put it in a bucket and dilutedAnd used a truck wash brush, it does say to spray directly onto surface, tent looks and smells like new again after a few seasons of useAnd while I had some still in the bucket, I washed my conservatory with it too, didn’t do a bad job of that either

I purchased this to clean our canvas bell tent.I was in two minds after reading all of the reviews however it is a pretty good cleaning agent.Our tent had turned a creamy off white colour with soot from Steam Rallies on it and general dirt.I used 2.5litres of cleaning agent and added 8 litres of warm water roughly.I used a powered sprayer to spray the mix onto the tent before using a soft sweeping broom to dip into the bucket and scrub the tent canvas.Whilst I was washing the canvas the cleaning agent soaped up well although didn't seem to be doing much by eye sight. However once I rinsed the canvas and let it dry it was a brilliant white againThe cleaning agent didn't clear all of the dirt, but the small bit that are left probably just need another going over but they're that small I won't bother.All in all this is a good canvas cleaning agent if used in a strong mix

This is a good weed killer, ABSOLUTELY USELESS at cleaning anything.I have tried 20-1 50-1 and neet on the gazebo canvas and nothing has changed. I have used a 10” new bass broom, a scrubbing brush.DOES NOT REMOVE ANYTHING.A TOTAL WASTE OF MONEY.Great customer service.Discussed issue with the seller who sent out a different product free of charge to try.I have applied the new product and now waiting 7-14 days to see the results.Further review pending.Having now used the AM-100 on the canvas gazebo the results are very impressive. I will be ordering some more.

The AT-55 looks good value from price point of view.In practise, the recommended 50 parts water to 1 part AT-55 quite frankly is too weak and struggles to foam up when using large brush to clean the Sauleda acrylic canvas.10 to 1 seems to foam up when brushed onto the canvas and perhaps work better. After the canvas has been rinsed with clean water and dried, it does look a bit cleaner, but did nothing for the algae and mould.If the acrylic canvas has green algae stains or has darker patches where rain water settled, you will need to use an alternative product to remove them. AT-55 is next to useless.Update:After using AT-55 in spring and autumn 2024, I decided to use a different product in spring 2025, 'Wet & Forget', to deal with the green algae. Claimed to be safe to use on canvas. To my surprise, it also removed the darker patches where rain water had settled. I thought this was ingrained dirt, but may in fact be mould. After a fortnight, I used AT-55 just as a general cleaner as I still had over 4 litres of the stuff....The AT-55 is a bit of a disappointment. Their FS-75 Reproofer is a better value product (compared to expensive Fenwicks).The photo shows part of a 'permanent' Sauleda acrylic canvas roof installed in summer 2022. Survived 3 winters to 2025 so far.

Used our Dometic Awning during the spring months and it got covered in mud, during the week and when packing away. So the mud even ended on the roof. Over the past few uses, tried to clean it as prescribed with soapy water, but as soon as it dried it was still visible. Researched several of these cleaners and took a punt on this one. Initially I sprayed it on left it a few minutes then brushed it from a bucket of clean water. Here we got I thought as it dried with no real difference. I then got the hosepipe out and repeated the spraying. This time, well what a difference. The black parts of the awning dried looking new!The lighter parts did need a bit more attention, but basically spraying on the product then blasting it with the hose worked.Would certainly recommend this product!!

It’s rare I have ever cleaned an awning much in nearly 30 years.Having recently bought one on eBay, it was quite mud splattered with red mud and seemed to have mould in the front mudwall.I bit the bucket and decided the best way to clean this Kampa travel pod air awning, was in the bath.It was a bit of a faff, especially getting it downstairs. But gave it a good wash and rinse.Got it up outside and rinsed off with hose pipe.Now a nice sunny day and it’s dry.Looks like a brand new awning.Very impressedAlso doesn’t seem to affect waterproofing.So much easier than hand sponging by area.Brilliant

I read the reviews before buying and they were mixed. This didn't touch my awning, not even the lightest of marks.

Just spent £20 on cleanerI wish I had waited extra day for this as it is truly amazingIn past had some crap off amazon.This removed and cleaned all mold mildew off tent.I wish I took a before and after photo but if I put a after photo you would simply say it was a new tent ⛺️Would recommend to any one with a tent or awning.Brilliant 👏 👏 👏
