Chemicals to clean Aircon? Not foam, please

[moonseeker]

Anybody can advise of product/name to clean air-con coils. I need the liquid stuff / wholesale. Foam does not penetrate deep enough. Thank you all. MS>

Toothbrush and toothpaste, I'm not kidding.

It's pretty cheap to get them professionally cleaned around ฿450 to ฿500 per unit ..complete strip down and high pressure clean I've tried cleaning them myself and never get the same results ...it pays for it's self in about 6 month because is works more efficiently (saves electricity)

If the outside unit (condenser ) is clogged with cooking grease it's very very difficult to get it clean without some chemical to help

I had a couple of " technicians" try to clean ours with toothbrush and high pressure jet not very clean.

they came back last time with a bottle of blue chemical ( stupidly didn't get the name of it maybe something alkaline) it cleaned up the aluminium fins very well, it also cleaned the paint off the kitchen cupboards so be carefull.
