Company details
Written by the company
Crikey Mikey was founded by Michael Irwin, a Chartered Chemist and Scientist, who was frustrated with the poor performance and high cost of outdoor cleaning and garden products. Using his extensive chemical knowledge and working alongside the UK’s Health and Safety Executive, Michael set out to create outdoor solutions that truly work and offer great value for money. Our first products, designed to remove mould, algae, and lichen, impressed everyone—including Michael’s 9-year-old granddaughter, whose excited exclamation, “Crikey Mikey!” gave our brand its name. Today, Crikey Mikey continues to develop innovative products that make maintaining your outdoor spaces simple and effective.

Unbelievable product
Unbelievable product. Applied to cream coloured flags covered in winter muck and algae and within 5 minutes they were clean and clear.

Pricey unless you dilute it
Pricey unless you dilute it. Otherwise does not really work out worthwhile price wise as you need a lot

Ok, but not great
Jet washed the patio first, then once dry applied the CM professional. It hasn’t gotten rid of some of the white algae and has left a bit of white staining on some of the slabs. But it did kill off all the weeds. Expected better from the most expensive product for this situation

They were out of stock
They were out of stock of their hand sanitizer. They did let me know and sent an automatic refund.

I have a resin patio with lots of moss growing in it. I have tried various weed killers , none worked. Thought your product would do the trick. It’s not worked so far. Applied a week ago. How long does it take to work?
Delivery on time .
brilliant customer service
I needed to contact your company on a couple of occasions as I couldn't locate the product I needed to buy and your customer service was brilliant, you responded very quickly and the advice given was spot on.
Good service and good delivery

I made a mistake when ordering and stupidly placed order twice and paid twice.
This was picked up the following day by Crikey Mikey and I was called by phone and the second payment was credited immediately and the order was delivered correctly within 2 days . Excellent service
Very poor results lichen still present…
Very poor results lichen still present after two applications. Had to power wash which was what I was trying to avoid. Complained to Crikey Mikey but not received a reply after 5 days even though they say they will respond in 24 hours.

Goods turned up when they said they would. Too cold to do the job, but has always worked well in the past
