Its always good to have a new professional sharing his knowledge here. Welcome aboard! Regarding your comments about hydrofluoric acid, I know it (like many other chemicals) are used regularly without known harmful affects. But it remains that this particular acid is a highly hazardous chemical. OK you may use low concentrations, but that doesn't alter the chemical character of the product. It is used (as you have confirmed) to etch ceramic surfaces. The concentration you use (however dilute) still etches. It therefor will have the same affect if anyone is exposed to it. When it contacts the skin, it keeps penetrating until it is neutralised by calcium. This means it eats through to your bones. The fact that the act of applying the liquid onto a slippery surface (by definition) has a risk of slipping and falling means it is a highly risky business. I'm sure you use all sorts of safeguards and PPE to reduce these risks, and neutralise the acid afterwards. I have grave concerns though, about any DIY applications of HF acid. The risks are real, and there's no way of ensuring the safety of a DIY operator. This link gives a bit of a picture of how deadly HF acid can be... http://adm.monash.edu/ohse/documents/ha ... ality.html Ash. Re: Slippery ceramic floor?! 13Aug 12, 2007 1:15 am Hi Ash,
I am one of the person who uses HF and have read what the largest supplier of HF (Honeywell http://www.honeywell.com/sites/sm/chemicals/hfacid/ ) provides on their website as well as various other articles all over the world about the subject,including that 1994 report you are referring to. I also would like to point out that that person has died from a very high concentration - 70 percent - of HF. What is considered "safe" - of course using proper PPE - in Oz is less than 1 percent and this is what the DIY kit contains. While HF is a highly corrosive and dangerous chemical, it is also used stainless steel and titanium pickling, glass etching / frosting, quartz purification, feedstock for chemical derivatives, chemical milling, and rare metal processing. It also etches various - not all - hard mineral surfaces without destroying them and making them safer to walk on when wet. It requires neutralisation and proper PPE (both of which is also supplied with the retail kit) and properly trained applicators who use a bit stronger concentration also have other personal safety equipments. Just like all chemical this one also has to be treated with respect and needs some understanding how to use it, but I have found that there is a bit of over reaction about HF among some professionals. I do not want to bore anyone with statistics from the Australian Safety and Compensation Counmcil's NOSI database and reports issued abut fall to the same level - vast majority is slip and fall - it states 13 .3 percent of all injuries at the work place. It is also the second largest cause of injuriy after manual handling. If anyone is interested the report is on link http://www.ascc.gov.au/NR/rdonlyres/981 ... ts0405.pdf as well as in the NOSI database. The statistics also show about 10 times more injuries falls on the same level than chemical aget caused injures. Slips and falls cost around 3 billion annually and growing with the aging population. I do not try to frighten anyone as there is no need, especially that these incidents in the vast majority of the cases are preventable. If you - or anyone else - require any further information - statistical or otherwise - please contact me off the forum and I will reply to you directly. This subject - HF and its dangers and benefits - are not strickly related to the base forum discussion. The only reason I have responded was to it to try to put some balance into the picture regarding to chemical remedial treatments, their suitability and limitations for floor surfaces.

I dont' usually use vinegar and ammonia together in the same bucket. If I've been doing a lot of deep frying, typically I will mop with ammonia & hot water first. Then rinse. Then use vinegar and hot water. Most times it's just vinegar and hot water. I don't really use any other cleaning products around the house besides vinegar & bicarb and diluted cloudy ammonia (mainly because I'm cheap and it works!)
