Well I have been wanting to try Bright All but wanted to try in my home first because I was concerned about sprayer clogging because its a powder and other concern was residue. I tried it on white Frieze and red plush pile with pet stains. I used a 2 gallon pump up sprayer and added 1 scoop to the 2 gallons the chem I used was DS-2 only because I already had it made up.
I experinced nozzle clogging right away probably because I did not give it any length of time to desolve completely. In about 10 minutes the clogging was gone. The white frieze came out looking great, popped more than usual Bright All may have brightners in it maybe John will pop in and comment. The red plush came out very impressive as well. Bottom line I suggest trying it I will continue trying on different carpet and stains as well. Some frieze carpets seem to be tough to get as clean as I expect so this may me just what the doctor ordered.
Oh yeah almost forgot the another reason I wanted to try it on deep red carpet was because I figured if it was going to leave white residue it would certainly show easy enough on deep red. I see no residue after the cleaning. Good Job, John!
