so, any recommendations on a lower pH product that still works?Looking on the bright side of this ugly reality, most grouted floors installed in the last 3 years very likely have any one of the new high performance grouts installed between those pesky tiles.
Mapei Ultra Color
Tec Power Grout
Hydroment Vivid... etc
all of which clean up very easily and don't require very high pH cleaners.
Nothing even remotely official or thoroughly tested beyond Mark and i's test samples but he's finding his 10 below isn't causing any issues I found that Prochem Axiom carpet and upholstery cleaner didn't cause any issues nor did Prochem professional tile and grout cleaner but it's of a higher pH and certainly more risky.so, any recommendations on a lower pH product that still works?
Looking at the Procyon tile & grout cleaner, comparing the sds sheet to Procyon Extreme which I use as my regular carpet prespray, it looks exactly the same. Maybe I will try it on some t&g. Under 11 pH.Nothing even remotely official or thoroughly tested beyond Mark and i's test samples but he's finding his 10 below isn't causing any issues I found that Prochem Axiom carpet and upholstery cleaner didn't cause any issues nor did Prochem professional tile and grout cleaner but it's of a higher pH and certainly more risky.
If you believe it to be a 3-year or younger floor then I would play it safe with a neutral pH cleaner especially considering the high performance grout factor
One I did had adhesive still on the tiles from installation.I had one last week that cleaned up super over 99% of the floor, but the 1% that didn’t stood out like a sore thumb. I ended up having to use oven cleaner on those spots.
Have a look at this link Dan, and then ask your LOCAL supplier for a compliance statement for their product https://jacobsens.co.nz/knowledgebase/codes-standards-information/slip-standard/do any of the current tile sealers have anti slipping claims like can be found on vct sealers?
Awesome info Mike!The Porcelain Tile phenomenon (updated 5-22-2021) - Mike Pailliotet & Mark Saiger
What we know:
Porcelain tiles in all shapes, sizes and finishes are being factory treated with problematic coatings during the manufacturing process.
Tiles dating back to 2018 are of concern.
The coatings can easily scratch.
The coatings can become randomly splotchy from cleaning agents ranging from 9 to 14 pH.
Sometimes the splotchiness can be removed with a mild acidic cleaner (pH 4-5) or a neutral pH floor cleaner along with buffing with a microfiber towel or bonnet and a 175 floor machine
The splotchiness can also be permanent.
The splotchiness usually occurs in areas that were pretreated by the cleaner and allowed to dry before extracting.
It is our belief that the floor owner can damaged the coatings with normal house hold cleaning products.
The more the floor is cleaned, the easier it becomes to damage the top wear layer.
This is a global problem.
What we believe:
These coatings are most likely slip resistant treatments.
These coatings could be protective to prevent damage during shipping.
Neutral cleaning agents do not create any issues.
The splotchiness could be something the homeowner or maintenance staff is creating, and we (Professional cleaning service providers) are only revealing it as we rinse the floors.
As of May 22, 2021 we don’t have a fix or a cure but testing of a two-part system out of Italy for Porcelain restoration will hopefully find a solution to fix both scratches and the splotchiness.
What we can do:
Professional cleaning services need to document all existing damage during the inspection process and have the customer sign and acknowledge.
Test for scratching.
Use the brush ring on your Spinner tool or hard surface wand
Be certain of the floor’s age prior to estimating or cleaning.
Risks involved to be stated in writing and signed and acknowledged by the customer.
Know how to positively identify Porcelain from Ceramic.
