Never thought of carb cleaner – will try it next time! I have been using straight isopropyl alcohol in a plastic bowl to clean my razor with every charge for years – probably since 2011. The dry time is greatly increased as the percentage of water in the alcohol solution is increased. I will be updating it soon. Probably brands carried by major hardware stores you’ll be able to find out exactly what they have, but the rotating no-name or minor brand stuff in supermarkets and discount stores is really hard to nail down. It needs to be diluted with water. In fact isopropyl alcohol is a standard cleaner for electronic maintenance and widely used in many different ways. Denaturants vary wildly, with some of them being Very Bad. I also find Lectric Shave to have a very oily texture that leaves a residue on my skin — I definitely wouldn’t want that on my shaver. According to Braun’s data sheet, they use either ethanol or isopropyl with a concentration between 60% and 100% (they do not state the exact concentration). This video shows an extreme example of acetone on polycarbonate, which causes it to fog, soften, and scratch even from the plastic dropper. Citrus Limonene based solvent cleaners are quite effective followed by hot water wash off and slow oven dry. Water is at least necessary. Besides, it’ also has dye in it, which may make all your stuff blue. less than 35% petroleum base oil (non hazardous heavy paraffins) (I even used Dawn non-concentrate and distilled water. I will add that I am loving my Panasonic shaver and I particularly like the fact that the cleaning station has a dry function which the Braun does not. I would firmly advise against that — the Panasonic sachets contain a special concentrated detergent that must be mixed with water in order to get the right cleaning solution. Thanks for the response Ouvidiu! Regarding the drying aspect, the inductive heating works best in combination with a fan (some Panasonic stations use such a system). Just make sure to clean it thoroughly after every use and follow the manufacturer’s instructions. Many different organizations use isopropyl alcohol (IPA) for wiping down critical surfaces so they can achieve disinfection. That’s a very fair point and I completely agree. That may leave companies using IPA for flux removal, stencil cleaning, and industrial degreasing in a difficult supply situation. No need for mixes or lubricants. I bought the products myself to use them with my Braun cleaning stations and thought it would be useful to share my experience.

That is correct, the paint chipping on the Series 7 is a well-known problem, acknowledged by Braun, but never fixed or addressed in any manner. Failing to do so will result in the solution overflowing the container during the cleaning process and prevent the shaver from drying completely. Thank you for your comment. I’ve seen two MSDS for it, one said 99% IPA and 1% inert proprietary ingredient, which I think was a fancy way of saying the remaining water. Is it any wonder isopropyl alcohol can be found in all corners of electronic PCB assembly, rework and repair operations? These traces of oil can subsequently cause malfunctions in highly sensitive electronics. Check out this post I wrote a while back, it should help you troubleshoot the issue. Remove the cassette from the shaver and let it air dry. I also found on those units, the properties of the rollers changed making them loose the friction needed to pull paper. I will continue using isopropyl alcohol just for testing purposes and see (and report back) if there are any long term problems with it. Just a heads up that 99% alcohol doesn’t work. While ethanol isn’t a strong solvent, it is typically sufficiently powerful to clean sensitive electronics which may have accumulated light layers of corrosion or dirt. Hi Ovidiu. ;) when not in high demand times, isopropanol can be considered “cheap junk”. As mentioned above, isopropyl alcohol is also available is a different grades, or percentage of solvent to water, to fit is specific applications. The only downside is the gallon jug is expensive–you can request a small sample bottle that will probably last you a lifetime though! Cleaning station remains with the red light (empty) after refillign with my own liquid (99% Iso propyl alcohol, 1% limonene). Then there are the sloppy ones, which petroleum distillation products – this crap leaves oily residues. It’s called Cleanerist and it works really well, the price is excellent and it’s ready to be used just like the one you linked.

Just make sure to give the cartridge a good shake and remove all the water before getting to the next step. 130mg of 91% Isopropil Alcohol 30mg cold water 5mg Glycerin 5mg Williams Lectric Preshave, It works for me using three containers alternatively but after a few years the container needs to be replaced to prevent overspill of the fluid. Once the virus crisis passes, IPA will be available again. Okay I guess if you absolutely must have IPA for something. The variety of solvents you can find in hardware stores can also change a lot depending on the countries. We bought in bulk for a small manufacturing firm and so had a good grip on any issues with additives but for at home it doesn’t cost much to buy a few brands and test for effects on plastics and such.

The 500 ml/16 oz of cleaning solution will be enough to refill a cartridge 3 times. Alas, almost all of the cheap and readily available aerosols have acetone as the principle ingredient, mixed in with methanol, ethanol, and assorted ingredients that together will probably make for a bad day. You are welcome, Tomas. Is there a downside to using pure isopropyl or pure ethyl alcohol instead of mixing the two? we use 96% ethanol with e80 gasoline in 1:1 prop. I strongly suspect though this ingredient list varies hugely from region to region. I am aware of these refills, unfortunately the seller won’t ship overseas to Europe, so I haven’t had the chance to try them so far.

The two questions I have are: A) I was aiming for the 9390 or 9385 as finally I thought I can clean by simply rinsing it down with water unlike the older model which I never dared to use water to avoid rust and malfunction. Difference between SD – Alcohol 40 – B which Braun is using and casual denatured alcohol is that Braun’s one is good to use in cosmetics and can come in touch with the skin. I didn’t know there’s a Shaver Shebang alternative for Panasonic detergent (their Braun solution is quite popular). Are you sure that the alcohol concentration and quantity are right?
