## Description

Review: 15% is what you need - this product is great. - This is what you need if you have stubborn black spots and lichen on your patio or driveway. I tried 'Pro-Kleen Ultimate Black Spot Remover and Destroyer' first and that was totally ineffective. This product is 5% more concentrated but 10x more effective. I used it neet and sprayed it generously so don't underestimate how much you'll need - probably goes about 50% as far as advertised. Obviously this will kill anything and bleech anything so wear old clothes, spray on a calm day, and keep well away from children, pets or plants. I left mine soaking for about 1hr before using a stiff brush to remove the stubborn lichen which came off quite easily. The results are incredible, from a 15yr old patio that has had little attention apart from the odd jet wash, that was heavily stained to one that looks literally as good as it did when I had it laid. I also used it on a concrete driveway that could be 50yrs old and that is looking so much better now. I can't say that it has removed everything on the driveway but nearly, and maybe another application could do it. I could not be more happy with this product. I'm sorry that I don't have any photos so you'll just have to trust me.
Review: Magic potion for removing black spots - This stuff is made by the cleaning gods! Excellent packaging and delivery. Very clear instructions on the back of the container. It is very important to follow the clear and sensible safety information. I mixed on a 1:10 ratio of SHC to water. After sweeping and jet washing my drive, I mixed this magical concoction, added a touch of Fairy liquid and using a stiff broom brushed into the blocks. Left for around 10-15 minutes then hosed it off. 20 year old drive came up so nice that three neighbours have asked me to help do theirs. It has the obvious bleach smell but use correct PPE or even dilute it a little more and it’s not any worse than your domestic bathroom bleach smell. Once hosed the smell doesn’t linger. Very effective in killing off weeds and removing black spots. Once dried I brushed in paving sand and sealed with Sika Path and Patio seal. Should last at least 2 years again without any weeds coming through if you seal the drive. Follow and use as directed and it will last a long time.

## Questions & Answers

**Q: Will using this to clean patios gradually erode or whiten the slabs?**
A: Cleans the slabs without any effort, rinse off with water. Read instructions

**Q: Does it kill weeds and slow growth?**
A: It is a very strong bleach and would probably kill weeds, grass and any plants close by. Not intended as a weed killer

**Q: How much do you need to use for a 12ft 1800 gallon above ground pool?**
A: Approx 80g per day, depending on useage.

**Q: Hi in regards to using on brickwork,pressure washing bleach off mortar to remove moss would to be too harsh & remove mortar?**
A: I'm pressure washing 50 years of moss growth from my roof, then spraying the chlorine to prevent re-growth. The loose mortar on my roof is coming away, but that's fine as it wasn't sealing anything anyway, and I'm going to re-point with new mortar when it's all clean.

### ⭐⭐⭐⭐ Worked on patio
*by A***E on 25 May 2024*

I purchased this as an interim solution until I could afford to replace my pressure washer. I've used it for the first time today and the results were instant! I used a 1:4 dilution with a squirt of washing up liquid. The patio will need a second treatment and so far there has been little impact to the white lichen spots. I have done my best to avoid plants and lawn but I'm really concerned about the wildlife and how best to safeguard the woodlice and spiders etc. as I'm sure bleach isn't good for them. Patio smells like a swimming pool currently. I don't know if regular household bleach would have the same effect but based on today's results I'll be ordering more of this stuff.
