Gunk 731 is an engine degreasant which has had quite a variety of uses in our house. It is specifically designed to clean the grease of mechanical items such as machinary and car engines. It comes in a 400ml spray can for just over 5 pounds.
The fact that this is in a spray aerosol can makes it very easy to use as you just simply aim and spray where ever you need it which can be in any direction even in an upwards direction which you would not be able to do if it came in a tub or spray bottle, the fact you simply spray it on also means you get to keep your hands relatively clean too. There is a brush on version of this but I have not tried it as I fear it would be rather messy.
As with any chemical you do have to be careful with this as it may irritate your skin if it comes into contact with it but has never had an adverse effect on mine but I do wash it off with in minutes and wouldnt recomend leaving it on your skin for a long time, do not get it in contact with your eyes as this will really hurt and be careful when spraying it as you dont want to breath in the fumes so ideally only use it in a well ventilated area.
As I said above it is designed to remove grease and grime from mechanical things, it works instantly so there is no messing around waiting for it to take effect like other cleaners so is a winner in my book for saving time. I had a oil leak on my car which marked the slabs on my drive way, the pressure washer on its own did little in removing the oil so I sprayed a liberal amount of this on then jetted it with water again which removed it all to my pleasure. I have used it to clean the engine on my car to be able to find out where the oil leak was coming from and to clean the engine after the leak. It has been used to clean the chain on my childrens bikes too as the lubricant on them had gone horrible.
Each of these cleaning operations has been really easy and I have been really pleased with the results, you wouldnt believe how tempted I am to give it a try on my chip pan but so far have resisted.
