It's pretty much gotten rid of all the black mould in my bathroom. I have tried many times with other products but, this is by far the best. Excellent value for money too.

For years our shower sealant has been riddled with black mould spots. Tried a widely advertised tube of mould cleaner, which made a difference, but the mould returned. Tried this product and it was a revelation. Had to reapply a few times, but it has completely cleared the mould. Highly recommended.

4.0 out of 5 stars Great product, poor trigger spray

I love this product. It works quick and it's very effective. I've been using it for my cleaning business for a long time, and always will.But! The triggers on the sprays are terrible quality. They always break after a few uses. Really wish they would redesign them to be sturdier so that I can buy the bulk 5ltr bottles and decant into the bottles I already have, so I'm not creating as much plastic waste.Please Pro-Kleen, make the triggers more durable for frequent daily use. Those of us in the cleaning industry really need it!

I bought this Pro-Kleen "Simply Spray" Mould Remover to rid the back porchwall of mould and mildew, caused by condensation and poor air circulationand find it works really well.Having applied it, leaving it for 30 minutes and then sponged it off, I foundthe wall underneath very clean and mould free.The active ingredient seems to be a very thick bleach, Sodium Hypochlorite,no doubt with some other anti-mould product.It works on Silicon Seals around the shower tray, Tiles, Grouting, and Walls,both painted brickwork and plastered surfaces, and kills mould, fungus andalgae.Users should wear thick rubber gloves when using this product as it is highlyirritant, keep it away from your clothing and other fabrics as it can discolouror cause bleaching and gives of a strong smell.It comes in a 5 Litre container, plus a 750ml spray bottle (already filled)you simply top it up from the 5 Litre container and use as when needed.Does what it says on the can and the label on the main container reads,100% Satisfaction Guaranteed. I paid £14.99 and got free delivery.I find it a 5 star product.

I have had mould in my window seals for years I thought we would have to dig it all out and redo it as i had tried most removers, but this stuff is amazing, it stinks and you need gloves but it is just awesome

5.0 out of 5 stars Just bought again 6 years later!

P.S. · 14 July 2021

Without doubt the best product I have ever used for removing and combating mould. Just purchased again after 6 years as needed more, I lend it to everyone and always get great feedback, I've cleaned black mould in high corners of rooms, black mould on fridge seal, I paint it on the back of wood when I suspect there could be growth, it's been used on the silicone in the bathroom a few times, amazing stuff.When using the spray must bottle I'd recommend eye protection and a face mask, I've gone overboard before in a damp room and my eyes and chest have suffered afterwards. Do not get on clothes as obviously it is a bleaching product and will discolour. Smells like strong bleach so my Mrs avoids using it, however she loves the results!5 star product.

This is an excellent product. Like many, I had mould stains on the grout within my shower despite it being cleaned weeky. I tried all the supermarket/high street brands including the one that says 'bang and the dirt is gone'. None of them shifted the blackness in the grout. Not even pure bleach and a toothbrush scrub. The cost of Pro-Kleen appears to be very expensive, but price per 100ml (I bought the 5.75L amount) worked out far less than I paid for other brands in the supermarkets.As soon as it arrived, I sprayed a little on the tile grout in the kitchen, over the hob to test it where there was some discolouration in the grout. I was really taken back by the result. Within 10 minutes, and with just a wipe with a damp soapy cloth, the grout was pure white again. Impressed, the following day I used it in the shower.The effects was exactly the same. I couldn't believe how effortless it was to use, and how little of the product it took. I used just under 200ml for cleaning the shower and now all the grout and silicone areas have returned to white.I wish I had known about this product years ago and not to have wasted money on all the common high street brands that did absolutely nothing.
