Nice vlogg & glad you did an Indian sandstone patio as that’s what I have although not as bad condition as that!! Jst try keep on top of it with my Karcher & patio cleaner & univesal cleaner. Is there a sandstone sealer to protect it from black spots and lichen etc… Great results here tho!!
Sealing can help prevent lichen spores, but the best way once you've got rid of them is a yearly clean and a mild biocide rinse to kill them. Lichen takes a couple of years to germinate, and then it spreads. A yearly biocide wash of 3:1 14/15% sodium hypochlorite will help keep them at bay.
I'm so glad you explained the hypo and the need for a Pressure wash first, this is the way I work, I see so many companies just soft washing and using sooo much hypo, I just don't agree with using too much of this stuff, great video ❤ Jenny x
@HandyChick I hate the "softwashing" term. It means I cant be bothered. Hypo reacts with the first thing it comes in contact with. If you've got lots of dirt and grime on the surface, it will only work on that and will have minimal effect on deep dirt and lichen. Pressure washing first gives the hypo the best chance of removing everything.
This video is excellent, just subscribed keep it up. I cleaned my sisters driveway with hypo but just sprayed it over 50/50 mix without jet washing first due to low water pressure on the tap it still did clean it a decent amount but the black lichen spots are still there, I now know why will try sorting the pressure and having another go neat.
We had a bit of white lichen on the pavement outside our house and when we blasted it off it lifted bits of tarmac off. I think that white lichen is quite acidic and you can see where it's been. On my brick wall i used a propane torch to burn it off and that put up a good fight. It also took a wire brush to fully remove it.
Hi Phil, If you buy a Sherpa deluxe 12v sprayer and use it to put down hypo then would that sprayer have to stay dedicated to applying hypo or it could it be cleaned out and used for other spraying purposes around the garden or would that not be advisable?
Hmm, I mean technically most gardeners would say have a dedicated pack. Since I don't spray weedkiller as you have to be licensed to spray for business use I only ever use it for hypo. Once rinsed I would say you could use it for different things but hypo will kill the std pump pretty quickly.
Just rinse, rinse and rinse lol. I aim to get it into a drain. I don't like it going on grass or flowerbeds unless the customer is fully aware of potential damage to plants etc.
@dannyrebeccag783 can go down the drain. Bleach ends up in the sink and toilet etc which is the same stuff. After rinsing it's well diluted, everyone has their own opinion but sodium hypochlorite isn't classed as hazardous by the water environment people. If it was they would stop people chucking in their toilets. It dilutes down very quickly. It's not like your dumping gallons of neat hypo down the drain.
@DirtyDriveAway that makes a lot of sense, there is just so much information out there and just trying to do as much research as possible. Thank you for your help! Keep up with the good work! It looks great!
@dannyrebeccag783 no worries. Yes, there's an element of being careful. It won't kill grass; it will turn the edges white, but it grows back. It's not a weedkiller. In strong doses it can kill plants but if your cleaning first, they should get a good wetting beforehand. Make sure any grass/plant areas are nice and wet before using and your good to go. Been doing it for 10years and never had an issue.
Thank you! I've watched countless videos trying to gain some insight into the business and I have learned more from this one about using hypo than all the others put together. The devil is in the detail!
No matter what anybody says hypo is magic. Forget all the namby pamby environmental spray and wait 6 months rubbish. If you want the job done hypo works everytime (so long as its fresh).
Great job! I've got a smaller job I'm doing doing at a friend's home with a bog standard pressure washer, would there be any benefit in agitating the hypochlorite with a stiff brush/broom before rinsing or will I just be adding extra work for myself? Cheers!
Hi, there isn't much need. The hypo will do a pretty good job at softening most of the dirt before you wash it. So long as it's fresh hypo and you're using a 3:1 (3 water to 1 hypo) mix or stronger, then it should be good to clean after about 20mins. 👍
The turbo is a bit more concentrated and you can run it at lower rpm to save fuel and water. The pointspeed would do the job but you would need a high flow rate/pressure to keep it spinning well.
Hello, Phil just quick question. pricing wise what's the difference in pricing, eg, with or without using hypo. 100sq mtr patio Indian sandstone etc. I have a big yorkstone area to clean swimming pool area patio path's etc what should I be quoting with or without hypo. thanks
Really depends what your doing with the hypo. Is it just deep cleaning or for lichen. Typically I charge 90psqM for deep clean hypo and then around £1.80sqm for lichen plus a £50 apply/wait/rinse charge on a lichen treat. Price to clean Really depends what you feel is fair. Yorkstone can be a pig to clean as it's so porous and lichen loves it.
@@DirtyDriveAway I'm just going give it a good clean with just the water at first see how it looks then probably go over it with hypo in some places where its not come up very well. I'm just going experiment be honest as I've not used before.
I have white lichen on my garage & extension roof but been told not to use a pressure washer on it, what would you recommend? I tried neat bleach but it wasn’t effective.
Yeah bleach won't work on white lichen. The only thing really is pressure. Because they are crusty spores chemicals don't tend to penetrate too well. Some people have tried wet and forget but again I'm not sure if it works on white lichen. Only way I can cut through them is with fairly high pressure.
Hi I’ve got some of the 15% sodium hypochlorite (black 5 gallon jar) and noted you talked about neat application. Have 1500 square metre yard(family’s) to clean using only Lance* and tractor PTO. I’ve done a spot today and the hypo made huge difference. So my question is what dilution rate is as effective as neat application as you seemed to mention other guys saying it’s wasteful (I agree on that but understand why). *There is a 24 inch whirlaway for sale close to me for £350 and seems a great deal but having trouble to persuade business operator to buy one. I can imagine that combined with bleach would get that area done quick. Using 2500PSI comet PTO washer / 8 gallon per minute.
If you have black lichen spores then it will need to be strong. I've been doing this for years and have tried many dilution ratios. In honesty I wouldn't go less than 75%hypo to 25% water on black lichen. Hypo won't kill white lichen as its crusty, it needs pressure. If its general cleaning and your not worried about the lichen spores I typically use 3:1 (75%water to 25%hypo) you could go a bit less but you would want to jet wash first as the hypo won't cut through too much before it's effectiveness diminishes. A whirlaway will make the job quicker over a lance.
Hello Phil great vids. is hypo safe to use on most surfaces.where the best place to purchase it. was thinking amazon or eBay but I see another of your videos about shelf life. just another question wheres the best place to purchase new lances & guns etc. thanks
Yeah it's good on most surfaces but use with caution on black limestone and tarmac. It can dissolve the bitumen in some tarmac. I would buy it from a proper seller/manufacturer. EBay amazon stuff is typically crap and not always full strength or fresh. If you have to buy online somewhere like bonnymans. Hypo has a half life of between 3-6months depending where and how it's stored. That means it's strength is reduced by half after approx 3-6months. So if you buy 14/15% hypo and its not fresh you may actually only have around 7.5-10% depending on its storage. You then water it down and people then wonder why it doesn't work. If your in the UK I always use damian at qservices in lancashire for all my guns lances etc. Tell him I sent you and he will hook you up with any bits you need. Phill
@raz khan a lot of people who use a lot of it have a local supplier. Some people tend to use bonnymans online but shipping is where they get you on the cost as its a hazardous material and can cost a lot to ship. Buying in bulk is usually the cheapest method but you'll be looking at around 300L to get a good deal.
Hi Peter, Thanks for your educational video! Hi from Australia. I have a small job to do on my balcony but it’s got layers upon layers of mold and lichen to get rid of. What brands/strengths of sodium hypochlorite do you recommend as I will need to see what is available in Australia. Thanks!
G'day, I only ever use 14/15% sodium hypochlorite as its the strongest commercially available here. You will want to if possible jet wash off as much of the dirt as possible. Then spray down some hypo and let it sit for around 30-45mins. You will probably then need to re spray it as its effectiveness tends to only last for around 30-60mins depending on temperature. If its hot you will want to keep it damp to stop it drying out. You should find after a 2nd hit most of the lichen will have gone. If its super bad you may need to hit it again but typically I can shift about 90-95% in 1 visit. There is no specific brand as hypo is made up of a salt like crystal which is dissolved in water to the required strength, hence why it turns back to a salt when it dries out. Research what strengths you can buy as some countries only sell 10%. This will work but it will need to be fresh and may need a couple of attempts. Cleaning first is they key to ensuring the hypo works its best. Phill
Just wondering if you could give me some advice, resanded my drive and sealed it ,unfortunately i obviously didn’t get all the excess sand off , and it’s dried rock solid in a few areas , is there any product I can use to remover the sand off the blocks ?
@@darrinperkins4842 in honesty not really as the sand will bind onto the blocks. If its a xylene based sealer you can spray the affected area with xylene chemical but that will soften the sealer and may just make a mess as your trying to remove sand. Unfortunately I fear your stuck with it for a good few years.
I have a local firm where I can collect from. Hypo at the moment has gone up because of supply issues. Not sure where you are but they cost with hypo is shipping.
As of 1/5/23 I purchased ‘Evans’ Hypochlorite, 25L tub (identical tubs to Phil’s, same colour and labelling) from an agricultural supplier, £24 inc vat. Mixed it 50/50 with cold water, it got rid of the Lechin mould spores and my block paving looked like new. Never use a pressure washer, I used a plastic planting trough £4 from Wilko’s, an 18” wide, medium bristle broom and elbow grease. Job done.
Top video mate. Got the dosatron myself and have found at 4/1 is does struggle for some black spot but for everything else ie render and roofs it does a great job
Yeah the dosatron is good even if there scale is a lil weird. It's actually 1of4 instead of the 1:4 which makes it 25%. Took me ages working out the 2 different scales lol.
Yeah I know that, it's the most common used chem to kill this. It won't have any effect on potential pointing work as it will have been diluted and neutralised by the time its done.
It's extremely bad that none of these so-called cleaning experts ever mention that many decorative slabs will be dissolved by even diluted bleach if it is left on for longer than about twenty minutes without being thoroughly rinsed off. There is only a few millimetres of sandstone laminate sitting on a concrete base and if you leave bleach on for too long you will be left with a grey cement slab. Pressure washing and use of something other than bleach would have to be carefully experimented with. Dilute bleach for twenty minutes does safely get rid of green algae though.
You really don't have a clue what you are talking about do you. Sandstone laminate? what world are you in. Firstly bleach is not an acid its an alkaline and secondly sandstone paving slabs are solid sandstone not a thin piece laid on concrete. These slabs are a good 25mm thick solid sandstone. If you have a laminate of sandstone on a concrete slab then you've been done. I've never in 10years of cleaning seen a sandstone laminated concrete slab.
Can’t say I can agree with one word Seattle wrote. I find this video fantastic and one of the best on this subject on u tube. Keep up the good work and all I can say is that guy has one huge chip on his shoulders.

Yes it's crusty and usually causes damage. Tarmac is quite easily damaged by pressure or acidic things
When you do your final view you could do with a before/after view just to remind us what it was like. Great job
