    Confused Hoshizaki 1900 Ice maker....Can I use muriatic acid to clean?

    Hello everyone! New member here... I have been in the HVAC business in San Angelo Texas for 12 years. I worked at mom and pops for doing residential service and installs for 6 years and then worked at the local college doing HVAC as well. While at the college I worked on just about everything HVAC... carrier infinity's, package units, split systems, LG ulti synces, minisplits, fumehoods, ptac, walk in vaults,, etc.

    In regards to Ice machines....I have worked on nothing but Manitowoc I know it is breaking the ten commandments to use anything but nickel safe to clean it.

    I recently bought a self vending RO and Ice water machine that has a Large Hoshozaki 1900 on it. It is now time to do the second semi annual cleaning and I have heard that I can use muriatic acid a a cheaper option because to coil is pure stainless steel. Is this true? The first time I cleaned it with Nickle safe cleaner and it quite frankly sucked and I was disappointed with the results and to spend the $90 on a bottle of cleaner.

    I am just overly paranoid to use muriatic acids as I have been drilled via manotic to use nothing but Nickle safe. Please give me yalls opinion.

    If cleaning you need to clean the inside surface of the evap too and the whole evaporator is not pure stainless.

    I would say that is a hard no. I've used small amounts of lime-a-way on really bad grids before to remove scale and deposits. It took many repeat cleanings over and over using small amounts and double overkill the rinsing x3 and toss the first few batches of ice.

    Did you say RO, as in reverse osmosis? Is this what the machine uses to make ice with? If so, there shouldn't be any minerals on the plates to have to deal with.

    I'm guessing this isn't the case though, and even with hoshizaki water filters the plates tend to get nice and crusty. Why is that?

    Anyways, try some non nickel-safe cleaner on it. Also get one of these long brush thingys if you you don't already have one.

    Local Pizza place has a Hoshizaki Square Cuber. We have to wash everything 2X a year due to all the yeast in the air.

    Owner had this restaurant for 15 years and recently sold it.
    However the last month before he sold it this problem came up.
    I was there for the new owner and have my suspicions.
    No other equipment is experiencing this like sinks, dishwasher, hot water tank etc.
    Has the pre filter and expensive second filter all changed since.

    RO doesn't necessarily remove minerals. Just particulate down to a certain size. So if the minerals are "dissolved", then they'll pass right on through.

    I do a triple evac with nitro to remove non condensables.

    RO water "should" be about as mineral free as anything.

    I would never represent myself as an ice machine tech but I use a lot of muriatic acid in my swimming pool & cleaning concrete. If the OP does use the stuff just remember you never add water the acid, only add acid to water . If you don't follow that #1 rule it will hurt you.
