how are presto washing powders?
Don't bother. Stick to either Ariel or Surf
That is from the pov of long term use and whether it's safe for the machine. Will these powders work for cleaning clothes otherwise. Yes, to an extent. So why not use them and save money?
^This review and others speaks of a white powder residue left behind. He refers to Presto as Surf which is the generic term for washing powder.
Most likely some filler which is present in other powders too but the difference is in over eight years I've never seen such white residue left on my glass door with HUL Surf and suspect Presto won't be good for the internals of the front loader over the long term
When using cheaper brands these are the telltale signs to look out for. Does the drain pump filter appear more coated than before. Is the glass door showing residue. If it is then go back to branded.
Check this
post and look at the white residue on the drum. At the time we were wondering what it was. Scale or not.
No, it was filler from any cheap detergent that collected over a long period. I've no idea how to chemically remove such a residue once the drum and spider get coated. And after that it's a matter of time before the spider fails.
Citric acid may help with removal
^A more revealing review
The white powder is lime. Caustic lime or slaked lime. Calcium hydroxide. This powder isn't very soluble, about 1gm dissolves per half litre and will deposit itself in the internals. Even in boiling water it remains sparingly soluble.
It could even cause sensor malfunctioning as this reviewer found. No wonder other reviewers were complaining about detergent residue in the clothes even with a warm wash.
^Presto for front loader is not suitable for front loader because it foams too much
Presto is an example of a 'B grade' product and is why to always stick to branded detergent
@sauravghosh
At least in India because Amazon has outsourced Presto powder to some local supplier. In the EU there are strict standards for detergent so if you see presto reviews from EU countries they won't be so bad. Don't get misled.
