I thought I'd do a quick demonstration of our new heavy duty cleaning kit, it's pretty powerful! The below picture is the front taken from a 'Deluxe' Aga range cooker during one of our re-enamelling projects but the kit works on all enamel parts including hob & lid rims. This cooker was installed in the mid-1970's and it had seen a fair bit of work! I chose white as it shows the dirt well, and hopefully the improvements that are possible with our new kit. I didn't even follow the full instructions for this demo, it was a quick and dirty shortcut!
I should point out that our standard, no chemical, cleaning kit will achieve results nearly as good as this; it will just take more elbow grease to achieve and take longer!
The picture shows the lower section of the front enamel plate including the two door latches which always attract a build up of muck, in this case a good 2mm of encrusted grease and dust!
Using a simple sponge scourer I carefully applied the cleaning paste to the enamel. I took care to get a nice thick layer over the thickest build ups. The paste is slightly abrasive but at this stage that doesn't matter we just want a nice layer of the area we want to clean as shown. Rubber gloves and eye protection are required and exposed skin should be covered. The paste though is relatively viscous and won't run/splash where it shouldn't. It has taken us a long time to find something like this!
I left the paste as shown above as wandered off to answer some e-mails. After two hours I returned to the front plate ready to rejoin the fray! I used the same sponge scourer to agitate the paste but moistened it with some warm water first. 95% of the improvement you see below was done with simple sponge scourer and paste. The final 5% was some super baked on bits around the latches mainly. These has been loosened by the paste but the sponge scourer wasn't quite tough enough to remove. They were sorted in seconds by one of our scrapers. A good wipe up and polish and... voila! This area is now perfectly clean, the black areas are chips to the enamel. Not bad at all!
