I hope this post clears things a litte!
There have been a few posts on here in recent weeks regarding alkaline cleaners. Whilst in a way some of the information is correct most of it is not. I realise for some members it must be very confusing and appear to be a "Tit for Tat thing" and to combat this I will now be introducing Colloid Cleaning Science into one of the modules on my courses in the future so that delegates can make their own minds up. The facts are:
"All Stone, Tile, Grout and Fixing materials are Alkaline."
So how statements can be made that Alkalines damage them is beyond me! Provided alkaline cleaner is used in the correct dilutions and rinsed properly, it is a safe way to clean stone, grout and tile. Clearly it is better to use a pH neutral where possible but heavy soiling often requires an alkaline product. Miracle as well as many other manufacturers make a variety of cleaners from ph neutral routine, to alkaline heavy degreases. Most are designed for safe use on any stone or tile surface. Miracle have for some time had products that clean in a way that introduces no alkaline or acid but simply makes molecules small enough to penetrate deep enough to allow mechanical cleaning. The subject is vast and I am happy to talk anyone through it who needs or wants a better understanding.
I hope this post helps people to understand a little more!
