Apply product at required dilution, hit it with my rotary and a stiff brush, mop up,constantly changing water in mop bucket.
What am I doing wrong ? Have been called back twice now, to 2 hard floor cleans,due to there being a haze on the surface I have cleaned, am I not rinsing enough ? I keep going until I get clean water in the bucket, obviously can't wait until the floors are dry, as I do them after doing all the carpets in the property.should I be adding a product to the mopping water ?
Or do I need a hard floor wand,so I can flood it with more clean water ?
Doing my head in, have to go back on Sat now and re mop one I did earlier this week, as there is a haze again.

All sorted, cheers Kev

Just to recap

Always pre wet the floor first we want the solution to work on the surface not sink into the tile and grout and this means the high alkaline works only on the dirt.

1.  Pre Wet
2.  Apply high alkaline diluted accordingly to contaminant.
3.  Scrub with Mono Rotary fitted with soft to medium brush and  allow to dwell.
4.  Agitate again and extract with wet vacuum
5.  Rinse with clean water or pH Neutral Cleaner and extract again

In case of really heavy contamination apply honing powder as well with step 3.

Kev

P.S. You will of course have someone come along shortly who will tell you not to use high alkaline on  tile which already has an alkaline content

[M.Acorn]

Cheers, it's only arisen,since I was told to up the mix by the facilities manager

These are the tiles,see what I mean about the carpet in close proximity,especially when the floor is on a slant, have to keep an eye on it.

  Kevin, when you have been involved in deep cleaning hard floors for over 30 years you might understand more about the negative effects of using high alkaline based harsh chemicals on any substrate, especially ones that are based on sodium hydroxide one of the most corrosive ingredients available which is also used to produce the two most hazardous cleaning chemicals used in any commercial kitchen area, those being machine dishwashing detergent and oven cleaners, Kevin i have said to you before i am the last person who should be knocking the use of harsh (sodium hydroxide ones) very harsh high alkaline based chemicals as they generate so much deep cleaning work for us, also after cleaning any surface with sodium hydroxide using water or a neutral pH cleaner will not neutralize the sodium hydroxide residues left behind, not that i would ever ever again use any product based on sodium hydroxide on one of my clients floors. and i can share all that with you without having to use any smiley faces.    regards  Tadgh

Carpets came up great.

So should I add something acidic too the rinse,to neutralise ?

Cheers Brendan,have to be top spec,results, not really able to say much about it,for security reasons.

  Hi M.D  the only thing i would add is read what it says on the sds about all the precautions you have to take when using sodium hydroxide, in a past post Kevin was boasting about his new extreme cleaner having a pH value of nearly 14, so i can only presume it is based on sodium hydroxide, if you like email me the sds to info@jskcleaning.ie and i will look at the ingredients and tell you what you need to use to neutralize the chemical residues left behind.   Tadgh

Why don't you follow Tadgh's advice and try his stuff.  I am bored with his posts and methods that anyone involved in commercial cleaning of large areas knows are not practical!   

Kevin

[M.Acorn]

Don't want to get involved in forum politics, it's not the product that is at fault, it was how I was using it that caused an issue and like I said it's only recently been an issue, since I increased the strength of the mix,on the instruction of the facilities manager,as he said the other contractor got better results than me,they want the flooring looking as good as new, regardless of how dirty and neglected it is to start with,some of the flooring I clean is very very,neglected,have tried other products and have found this has been the best,regardless of what it's made of.

  Kevin, why did you invite me into this thread in the first place, if you can stand over using sodium hydroxide on your clients surfaces fair bowls to you, i will tell you it will come back to bite you, remember Kevin i've been there and yes using high alkaline based chemicals based on sodium hydroxide did cost me and on more than one occasion, so if you don't want to take that onboard thats fine by me.

[Kev Martin]

Strange!  So how do you account for the fact that we have cleaned, restored, repaired and sealed 1000's of floors, walls, tables, statues and valuable antiques for some of the most demanding clients I have ever met in a lot of cases using high alkaline, acid, chemicals and honing powders including but not limited to:

Marble
Granite,
Porcelain
Ceramic
Basalt
Travertine
Terrazzo
Concrete
Quarry
Encaustic
Geometric
20 Plus different types of Slate
Saltillo
Brick
Travertine Filled and Unfilled
Limestone
Linoleum
Amtico
Karndean
Altro Flooring all grades
Quartz
Sandstone
Soapstone
Coade Stone
Flagstones
etc etc

and never ONCE had a call back then???

i love to see you guys in the pub drinking whisky together

  I know what Kevin would like to put in my whiskey (NaOH) and that would be one way of shutting me up for good.

but Tadgh, whisky is an alkohol, C2H5OH
so its alkaline, you would be allergic to it  so no need NaOH, unless somebody wants to be sure you will have a good headache

  Thats quite true Radek, even though i do have an aversion to whiskey, but would sink a few beers, but my aversion to sodium hydroxide is very strong but with very good reason, and as this is a forum for sharing ideas and experiences i have shared my experience of using sodium hydroxide many times on here.

[M.Acorn]

All sorted out, turns out it was this one that was an issue, all the others I have done are fine, todays job was a breeze, only needed minimal chemical as floor was pretty clean, just used my carpet wand to suck up and flush much easier and got home just as posty was taking my wet vac too the post office over the road (cheers Kevin)



And part of what I did today..

[Dave_Lee]

MD, so just what was causing the haze appearance, was it detergent residue or something else?
