Harris Hydrogen Peroxide is recognized as one of the cleanest and most versatile of all chemicals. Its strong oxidizing properties make it a powerful bleaching agent, stain remover, and multi-purpose cleaner when used as directed.


Extra Strength - 12% concentration is 4X more concentrated than standard hydrogen peroxideNo Additives - Just H2O2 and water, no additives included of any kindCountless Uses - Whiten grout, clean marble, brighten whites in laundry, treat carpet stains, and so much moreSimply Dilute and Spray - Makes 4 gallons worth of ready to use cleaning solution


To Use: 

Kitchen: For cookware: Loosen baked-on crud, sprinkle bakeware, pots, or pans with baking soda then spritz with your dilution. Let sit 1-3 hours then wipe. Clean your dishwasher: Spray diluted solution on difficult-to-clean parts and crevices – run dishwasher as normal.

Bathroom: Whiten and brighten bathroom surfaces and grout: Spray dilution and allow to site for 5-10 minutes. Wipe excess with damp sponge or cloth. For grout, spray dilution and allow to sit for 5-10 minutes, scrub with sti-bristled brush. For tubs/porcelain, spray dilution and scrub with sponge. To clean and whiten toilets: pour about 1⁄2 cup of diluted product in the toilet bowl. Scrub with a toilet brush, let sit 20 minutes then flush.

Marble: To clean and brighten your marble, make a paste by mixing 2 parts baking soda with one part diluted product. Mix to form a slurry using an old toothbrush or other stiff bristled brush. Apply directly to marble and grout, leave it for 5-10 minutes, scrub again with toothbrush or stiff bristle brush and then wipe/rinse clean with wet sponge or towel. Test in an inconspicuous area before applying.

Laundry Booster: To brighten your whites: Add diluted amount to your regular whites-only wash load to brighten dingy white clothes. Pre-clean Laundry: Dab directly onto stains (grass, blood, wine, food, etc) to attack stubborn stains. Note! Test for color-fastness first.

Carpet: Use diluted product and spray directly onto stain. Let it sit for 10-15 minutes, then remove with a sponge or cloth. Press down to absorb excess liquid. If the stain remains, you can repeat treatment.

Hard Surface Cleaning: Spray dilution on, allow to sit for 10 minutes then wipe dry. Shine mirrors and glass – simply spray dilution on and wipe for streak free cleaning.

Not all great stereo systems meet all the requirements for connectivity.
I want to go on record, the Onkyo TX-Nr7100 is an awesome choice for a stereo avr. Great connectivity, a warm sound quality, and many options for your audio sound choices. But, because it's base connectivity, as it applies to Bluetooth, I do not recommend to connecting a PC to it. Due to audio and video, data separation. The Onkyo, though an excellent stereo choice, has problems playing Youtube and other types of media, with built in audio and video playback. It defaults to the miniplayer, built into the system and is impossible to get rid of in these situations. I give this product 5 stars on quality and performance, but it was not made to connect to a computer. Stll, I recommend this AVR Stereo Receiver on its aesthetic look, sound, audio and connections and quality. Very important to keep this in mind for Computer and gaming console connection to this system.

Exceptional Home Theater Receiver with HDMI 2.1, Dirac Live & THX – Incredible Value
After researching extensively and using the TX‑NR7100 firsthand with a 5.1.4 Dolby Atmos setup, I’m thoroughly impressed by its blend of features, performance, and value. Setup & Interface The guided setup process is smooth and intuitive—Wi‑Fi setup, firmware updates, speaker configuration and HDMI mapping all work seamlessly. The on-screen menus are clean and accessible, though some deeper options may require a bit of navigation With six HDMI 2.1 inputs and two HDMI 2.1 outputs, this receiver supports 8K/60Hz and 4K/120Hz video formats, along with VRR, eARC, and ALLM. This makes it ideal for gaming consoles like PS5 and Xbox Series X—performance is solid with no reported signal dropouts on the primary HDMI ports. Audio & Sound Quality Every channel delivers up to ~100 W into 8 Ω, powering immersive content such as Dolby Atmos and DTS:X with clarity and presence. THX post-processing adds dimension and scale, especially with cinematic soundtracks. Dirac Live room correction provides musical staging, precise imaging, cleaner dialog, and deeper bass—transformative for untreated or irregular rooms. Streaming & Multi-Room Equipped with AirPlay 2, Chromecast, Bluetooth (including aptX), and Sonos/DTS Play-Fi integration, streaming is flexible and robust. Spotify, Tidal, Pandora, TuneIn, and more are all supported. It even functions as a Roon endpoint with no signal issues when streaming high-res audio over Ethernet. Build & Design The front panel features a large green display, a straightforward volume dial, and basic controls. While the remote is functional, it isn’t backlit. The control app is usable but somewhat basic, making desktop Dirac calibration a better option for fine-tuning. Pros: Cutting-edge HDMI 2.1 support for 8K/60Hz, 4K/120Hz, VRR & eARC THX Certified with immersive Atmos/DTS:X and IMAX Enhanced support Powerful and convincing Dirac Live room correction Versatile streaming ecosystem and smart assistant compatibility Excellent price-to-performance ratio compared to peers Cons: HDMI glitches possible; best addressed via firmware updates and proper setup Remote is not backlit; app UI is basic Not truly expandable to 11-channel systems; no independent sub outs or extra preamp channels Verdict: The Onkyo TX‑NR7100 strikes a remarkable balance between modern video support, superior immersive audio, and intuitive usability—all at a price point that undercuts many similarly spec’d competitors. If you want future‑proof HDMI features, strong gaming performance, Dirac‑based room tuning, and multi‑room streaming options, this AVR delivers beyond expectation. Highly recommended.

Best deal and beautiful sound
I bought this one on sale to replace my old Pioneer VSX-1120-K 7.2 ch receiver which did not support 4K video and new Atmos sound profile. I would say, it was the best deal in this category since it offered 100 watts/ch , 9.2 ch, 8k/4k supported, and nearly 50% price cut when on sale! The sound quality is amazing, especially after using Dirac live to measure and auto adjust all speakers’ sound curves, making my home theater sound in a different level. The high is very clear but not harsh while the low is soft and nice punch. I also like the Onkyo App which helps to control the receiver in many ways. I can use it together with other online music streaming services app without touching the remote controller any more, very convenient! The only a small problem it has, is that it’s BD/DVD HDMI input sometimes does not work well with Amazon fire stick. It makes the firestick restart over again and again, so I have to use the other input such as game input to work smoothly with the firestick. Update: I have had this receiver for more than a year now. I would say, I love it more and more! It not only supports 4K/8k video through HDMI, but also has so many listening sound models to choose from, and the App on smartphone is a very convenient tool. One of my favorite functions of it is the Dirac live function. I used to analyze the sound characteristics of each speaker, and fine tune the frequencies on them, making my home theater speakers up to a very high level, making every single sound frequency is in its best condition. This certainly compensates the shortcomings of certain sound frequencies in each speaker. Many times I just sat in my home theater listening to the music from Spotify without watching movie, and it was so joyful. I am changing the rate from 4 stars to five!
