Cleanit
Hello:yikes:
I am cleaning these tiles for a local hotel and spa, the thing is when the place was build 4 years ago, the tiles where layed first before anything else so they got alot of dirt, plasterdust, grime and you name it ground in and they where not cleaned. Since then with under floor heating and the chlorine and other chemicals in the pool, not to mention the bacteria off us all have taken its toll and formed what looks like a layer over the old dirt and has set it in.
The tiles look like ceramic or porcelain and are turning greyish black especially around the areas were the water has been settling/trapped. Only the traffic areas are mainly effected.
I have tried a really strong tile cleaner and it does not budge it:mad2:, so I tried some acid (brick acid cleaner) and that does the job but since the tiles are close to the pool I don't want to use the acid if you know what I mean, is there also a chance the acid will damage the tiles?
If anyone has knowledge on this I would really appreciate it:hurray: thanks
